Incompatibilities

In this very nerdy tango-related post, I want to point out, how some common follower’s techniques or habits can make improvisation and navigation difficult and a comfortable embrace or good connection hard to achieve. 

I know that this post might antagonise female dancers - as much as my last blog was popular amongst women. Please be assured, that I do not write to insult or criticise, but to help create more awareness about the outcome of specific tango techniques. 

I am here not speaking about beginners who are struggling with their posture and actually might not yet have a technique. This is why I will not comment on issues that are considered as "mistakes", no matter what approach you follow: bad posture, a general lack of control over tension and relaxation, not carrying the weight of your arms, hanging on your leader or pushing too hard against him/her, stepping away from your partner, not knowing the music, not actively taking spaces...
Let’s assume that a dancer with some experience has sorted out most of those issues or is as least aware of them.

I am explicitly addressing "advanced" followers. You will dance at Milongas, Encuentros and Marathons. You look super elegant and do the most complex moves with ease. You might even be a successful teacher or performer. But that does not mean that your techniques are universal or helpful in all situations or with all partners. 

Don’t get me wrong: I do not think, that followers should have to adapt to every technique of any leader. On the contrary, that is the leaders job as well. I will, e.g. not pivot when not being given the space to build up my top-to-down spiral. But I will usually find a way to make the movement happen without having to compromise my ideas. Or I will not do so, being aware that this leader might not want to dance with me again. It is my choice. But I assume, that very few followers consciously want to hurt their partners or block movements. This is why I will describe advantages and disadvantages of techniques and habits.

I am aware that how I useful I find a technique, is defined by my priorities. Let me point them out:
  • A soft embrace and deep connection
  • Organic and comfortable movements
  • Real improvisation
  • Musicality
  • Social dancing
As I have written before: for me as a social dancer, it is about how it feels from the inside and not how it looks from the outside. Elegance is a plus, but no top priority. And my priorities determine the techniques and concepts that I use and teach.

Other teachers or dancers have different priorities and will therefore use differing concepts and techniques. So when I am disappointed by someone’s technique, another leader might be perfectly happy dancing with the same person.

Before shrugging off my blog as the quirky ideas of a mediocre dancer, please remember that I have been teaching for 18 years all over Europe and the USA. Therefore: If a follower’s techniques are incompatible with mine, they might be incompatible with others as well. Not least with the ones of my teaching partner. How often do you think that Detlef is disappointed by how uncomfortable a dance was and by how little he could improvise? I still remember when he came back from a milonga in Rome, almost having cried on the dance floor, because none of the women was willing to do a shift of weight to their right foot.

In this blog, I am mainly writing from the perspective of a leader. Let me comment on that as well:
As a teacher, it was alway my standard to understand whatever we do in class from the perspective of both roles and be capable of leading it. This is why all of the following observations have been confirmed in the class context as well as on the social dance floor. In a crowded ronda, in a close embrace, I usually stick to simpler movements than in class: variations of the walk, milonguero ochos, simple turns… The more disappointing it is, when some of these very basic moves will absolutely not function.

Sure, I (like any other leader, also Detlef) make mistakes, but please be assured, that after so many years of in-detail analysis, I will always be able to tell, why a movement did not function in a given moment. So when I could not step out to the right lane, I might not have prepared this properly by turning my leg in the hip and by this opening a space. But it might also have been the follower’s doing, because she did not open her left side due to her asymmetric embrace. In this complex dance and communication, both partners contribute to the successes and failures. This post is about the follower’s part in the interaction.

My dear friend Ms Hedgehog has recently written a great blog on what it takes to be a good social dancer. She focusses on the positive aspects and I agree with everything she writes. But because of being my usual critical self, I will rather present a list of techniques and habits that can make the dance less agreeable or even limit improvisation significantly. 

The order below is coincidental.



1. Projection of the free leg
This is commonly taught by teachers with the idea of "making space for the leader’s front step". With the tiniest invitation, the follower will project her free leg to an extended position using a significant amount of muscular control in this leg. 
Advantages of this technique:
  • Lazy leaders get super results. They just hint at something and the follower will terminate the whole move on her own.
  • Looks very elegant because the legs are nicely extended.
Disadvantages of this technique: 
  • The leg is not really free and lead-able. Changing the length or speed of a step, as well as re-directing or stoping the movement is much harder, because the leg is already on a trajectory towards an anticipated direction. Therefore improvisation and musicality will be limited. 
  • Often, this technique inhibits small steps altogether, because the leg will be extended into a long step on principle. This will endanger navigation on the social dance floor. It is not always the fault of the leader when a follower runs into other dancers and hurts them by stepping down with a lot of energy. 
  • Loss of connection. When dancing with a follower who uses this technique, I will only feel connected in the initial moment of the movement, but during the transfer the connection is lost because her leg moves independently from her gravity centre. I would like to feel connected on every inch of the transfer.
What we teach: We concentrate on pushing from the supporting leg and letting the free leg move with the gravity centre like a pendulum. It is relaxed and has roots in the floor. Thanks to this approach, we also never have to think where to put this leg. Agreed: It looks less elegant.


2. Closing the position as quickly as possible
This technique is often connected to the projection of the leg and has the same advantages and disadvantages. In particular traspiés (or rock-steps) are difficult to communicate because they happen in the open position and leaders often have to stop those followers with their arms in order to prevent an automatic closing.
What we teach: a closing will eventually happen by a complete transfer of axis onto the new supporting leg and coming back (up) to a straight leg.


3. Overactive rotation of the hips and automatic pivoting
A lot of teachers stress that the hips most be rotated as quickly as possible in order to allow for speedy pivots with a big angle. 
Advantages:
  • Leaders, who don’t want to dissociate get super results.
  • Pivots and ochos remain a follower’s movement and nothing in the leader’s body will distract from it. (Or this is what a famous teacher once told me.)
Disadvantages:
  • Basically the same as in 1, because improvisation and connection are inhibited. Ever tried to lead a milonguero ocho (without pivots) with such a follower? Or just change the angle of rotation in a pivot? Impossible, because she will automatically rotate her hips to a maximum. Or try rotating your upper body towards your partner to compensate for an offset of feet: she will most likely pivot a little and therefore the next step might go into a different direction than intended. Walking in crossed system is often impossible and unintended crosses happen. 
What we teach: Lazy hips. A rotation will only happen when it is communicated by an opening of space around the axis of the follower, so that she can create a spiral in her body from top to down. No opening equals no pivot.


4. Step on one line
A lot of teachers ask followers to walk on a virtual line, therefore they will position one leg behind the other when walking backwards or forwards. 
Advantages:
  • This is elegant because the position will always look closed. Leaders who change direction with almost every step, might never notice the disadvantages of this technique.
Disadvantages: 
  • Try walking front-to-front with such a follower’s technique for more than 2 steps. It feels very weird, because she will aways position her free leg directly where you want to go with your next step. You constantly have to compensate by opening your position laterally. Later have her walk on two lines and follow her free leg. That will feel completely different.
What we teach: Step on two neighboured lines.


5. Have musical automatisms
A lot of followers will automatically double the speed in a number of movements: the Ocho Cortado, the cross, the back and side step of the molinette structure… This comes from teaching steps linked to fixed rhythmical patterns and I cannot find any advantages in this approach.
Just imagine: I want to lead a turn in normal speed to slow music, starting with the back step of the follower - I invite her to pivot and - whooosh - she’s already finished the turn. ARGH!
Also the contrary is a problem: you might want to speed up for a longer time because the melody says 12341234 (think D’Arienzo), but she slows down after the second step (123_), because she is used to quick-quick-slow patterns. It will be impossible to interpret the melodic rhythm.
What we teach: Adapt the movement to the music. Don’t ever memorise a rhythmical pattern with a figure. Learn any step/figure in a default variation (normal of half speed). Then practise changing speed in every possible position.


6. Have movement automatisms
The result of traditional step learning is that followers (and leaders) will develop very strong preferences for certain movements and are often incapable of dancing variations. 
I mentioned above how Detlef often does not succeed in inviting followers to do a simple shift of weight to the right foot because they block the movement. No problems changing to the left.
Sorry, but I cannot think of any advantage in creating these strong habits, so I am just going to point out some of the typical habits:
  • Dancing a cross only on the usual side and expecting to be "forced" into a cross with the right left in front of the left leg instead of just reacting to the same leading mechanism on the other side.
  • Being used to stepping forward with the left food in the "8-count-basic", but blocking any front-to-front forward movement with the right foot. Walking forward with the right leg on the outer lane in an ocho cortado might still work, but stepping forward into the space of the leader just will not function. Trying to prepare this step forward, I had followers change leg, turn their hips or even fall onto me, because they rather do a volcada than stepping forward with their right leg. Ask Detlef to tell you his story of that very tall and heavy follower doing a volcada instead of a front step. His back was hurting for days!
  • Cross or uncross automatically. Do you know, how many variations there might be around the traditional cross - apart from doing it on the other side as mentioned above? And did you know that you might prevent a leader to walk on the outside lane for a longer period, because you cross automatically after 2 steps? Are you expecting him to "block" the crossing?
  • Automatically projecting your leg into a back step after a pivot because you expect an ocho to happen. What if the leader takes the pivot back?
  • Automatically rotating the hip to a neutral position after a back or front step in a turned movement, because you expect a side step to happen. This result of lifelong molinette practise will prevent any variation in turns.
The list is endless. Unfortunately, these automatisms prevent everything that goes away from the traditional patterns as well as any real improvisation without fixed patterns, based on freely linking the smallest elements.
Sure, if you dance with a leader who repeats patterns without actually communicating them, it helps to know them in order to make the dance work. But do you really want to be so unflexibel?
What we teach: Be prepared for any movement in any given moment. Also: Relax the free leg and let it fall towards the floor with its own weight, so that your body is also physically prepared to react naturally to unusual and/or subtle movements. 
A note: Yes, dancing with leaders who really improvise can be challenging and might feel stressful. Even I sometimes enjoy dancing with someone more predictable, in particular when I am tired. But I would not always want to dance that way.
A second note: Dancing with very creative leaders requires much more focus on the communication, so there won’t be much capacity left for decorations. You either have to ask more actively for the time/space to decorate or skip decorations altogether. Which is what I do. And you won’t see a lot of followers who are dancing with Detlef do a lot of firuletes either.
A third note: Yes, even Detlef has these automatisms because he learned tango based on steps before we started teaching and breaking up these patterns. In the first years, we also taught more figures but nowadays, we seldom teach steps anymore. And if we do so, we will vary them in manifold ways to prevent automatisms. This is why some of our students dance much more freely than we do. 


7. Push with the head
I don’t think that any teacher consciously instructs followers to drop their head or to push their forehead against the leaders right cheek or forehead. But a lot of advanced dancers do so because of misunderstood cuddling or the wish to imitate the aesthetics of famous dancers. 
Advantages:
  • Looks feminine?
Disadvantages: 
  • Starts hurting after a while because of increased tension of neck-muscles. 
  • Leaders move their head into a left-bent position to get out of the way. (I once watched Detlef tilt his head more and more to the side because of the follower invading his space with her head. He looked really stupid.)
  • Inhibits movements to the so-called closed side. (See 7.)
  • Often has a negative effect on stability of axis, even without the pushing.
What we teach: Hold the head upright and in line with your spine. Search for head contact only if it is anatomically possible.


8. Push with the right arm and/or asymmetrical embrace
A high tension in the right arm of the follower is very often taught in combination with a stable v-frame. Often followers are told to give resistance so that force (or at least tension) can be applied to communicate pivots. In the v-embrace, the other side is often closed and the two shoulders will usually be much nearer than the ones on the so-called open side. I know that v-hold does not necessarily imply a pushing arm, but the problems created are comparable.
The positive effects of this technique:
  • I am not sure, but one obviously does not need dissociation. A follower can remain more passive and let herself be pushed or pulled into pivots. The strong frame might also increase stability when doing automatic pivots with a spiral starting below (see above). It is certainly easier than doing pivots actively by creating a spiral from top-to-down. 
The negative effects of the technique:
  • Any pushing or tension in the arms just feels less comfortable and starts hurting after a while. Even Detlef (who works out on a regular basis) can sometimes barely stand the pain a fragile follower causes with her strong right arm. You don’t believe me? Ask him.
  • With a right rigid arm, the follower pushes herself into an asymmetrical position. So even if a v-shape is not intended, an open and closed side are created. You can see that with many "milonguero" dancers who are starting out with a parallel chest-to-chest position, but then open to a v-hold in ochos or turns.
  • A general v-hold or pushing arm results in movements feeling uncomfortable or even being impossible into one direction. Try to walk on the right outside lane in parallel system with a follower who pushes with her right arm or brings her left shoulder so much forward that she cannot dissociate to the left anymore. You won’t succeed. Most likely it won’t even be possible to walk straight without her pulling you to the right side, because she not only opens her right side but also turns her hips with her as a result. This makes navigation really hard. And please examine your back-ocho technique: there will often a nice opening for an organic pivot on the follower’s right leg, but the pivot on her left leg is initiated by the leader pulling her with his right arm.  Or she will pivot automatically. I find it illogical to use different techniques on the two sides.
  • In general v-shape will also affect all musicality as it inhibits free change of speed and step length on both sides. (This is a huge topic!)
What we teach: Have soft arms. We want to embrace, not to have a stable "frame". We connect and exchange information in the centre. The leader opens spaces that the follower takes actively. We are therefore searching for a parallel position of the upper bodies and want to be free to execute all movements comfortably to both sides.
Note: When dancing with a leader who uses either active pushing/pulling with the arms or at least relies on the stable frame for building up a tension for a pivot, I will not compromise my priorities and start pushing, but rather find other ways to make the movement work: Either create a counter-spiral in the body or not pivot and reach the end position by doing a milonguero-ocho. My arms remain soft.


9. Dropping, lifting or swinging the hips
Sometimes this comes from the wish to look sexy and might result in a slight difficulty of taking steps back speedily. But very often such a hip movement comes from consciously or inadvertently wanting to pull the free leg to the axis in the end phase of movements. In dynamic steps the phenomenon might not occur, because the initial push is enough to transport the axis fully to the new leg, but try a very slow transport of axis in a back step of the follower. In the last moment it might feel, as if the follower is breaking away and her axis gets wobbly.
What we teach: The hips remain calm and parallel to the floor. The transfer of axis is done by the former supporting leg that pushes until the axis is above the new leg in particular in slow motion.


10. Be overactive
A lot of advanced followers seem to think, that they constantly have to do something in order to dance interestingly or musically. They will decorate, insert double steps, change weight without invitation, move, move, move. They never stand still. Being calm equals being boring. Right?
This is very handy for leaders who do not have a clear leading technique or who are un-inspired, but I think that constant activity makes it impossible to build up a more intimate connection. Sure, feel free to fill spaces, to add to the dance, to give input to the leader. But please: don’t move all the time. Can we not just stand for a second. Slow down? Enjoy the embrace? Just listen to this tiny piano fill? Just honour the end of the phrase? Does tango have to be so nervous?
When I dance with a guy who expects me to act all the time without inviting me properly, I might do so. For a short while. But then I usually get bored, because of the lack of interaction and communication. So I might just stand and embrace. You’d be surprised at what can happen then! 


So. This is it. Sorry to be a know-it-all. 

I am aware, that every dancer will make her personal choices. I always assure our students, that our techniques are just options amongst many. But I am strongly doubting that everyone actually makes conscious choices. I so wish that advanced dancers were more aware of their techniques and possible outcomes. Not only for the sake of the leaders, but for your own comfort and clarity. So that you can make better informed choices!


P.S.
Some might think, that they now understand our entire technical concepts. Nothing I can do about it, apart from saying: buy our Book + DVD Caminar Abrazados and you'll how much more there is to it. Or visit one of our classes. You might be surprised. And no, I am not ashamed of self-advertising. ;-)

ABC of Tango Events - No More Porridge!


Tango defies all kinds of standardisations. It is a highly individualised tradition based upon the personal views, styles and philosophies of thousands of people all over the world. This is what makes tango so complete and interesting. I certainly don‘t aim to downsize its diversity or the inventiveness of organisers in creating new forms of get-togethers. It can nevertheless make sense to define certain forms of events or more accurately: to describe some commonly agreed-upon categories of events.

Why is that?

When I started dancing tango, there were just a few local milongas. Once in a while the local teachers would invite an external (usually argentine) teacher couple and maybe even a tango-orchestra. And then you’d dress up and call the event a festival, because it was more than a normal milonga. Expectancies were not very well-defined and life was easy. Everyone ate porridge.

Nowadays, there are many different forms of events that have developed based on the philosophies of sub-groups and organisers in the tango community. Sure, there are still those who dance no matter where to no matter what music in no matter what style. When you start out, that might even be normal. But the majority of more experienced dancers will develop personal preferences. Some like dancing to the “old” tango orchestras, some prefer non-tango-music, some love live bands… Most dancers will choose evens quite consciously and spend a lot of time, money and energy to fulfil their quite accurately defined and  sometimes exaggerated expectations, like someone who visits a restaurant:
You know, when I order a Diet Coca Cola, I don’t want to be served a Pepsi Max, because I really don’t like the taste of it. When I order my steak medium, I don’t want it raw. When I order Paella, I don’t want to eat Risotto. And a Pizza is no Flammkuchen. These dishes might be related, but they are not the same. 

In order to prevent their customers from being disappointed and themselves from having to listen to complaints, I think that organisers better describe their events as honestly and detailed as possible in advance. This is where labels come in handy. If everyone agrees upon what a marathon is, an organiser can use this single term to describe his or her event very accurately. If an event will not fit into a commonly agreed-upon category it will of course need a more detailed description.

Unfortunately, a praxis of (intended or uninformed) mis-labelling has spread in the tango community and customers are confused. 

An example: Two years ago, local organisers promoted an international Festival-Marathon-Encuentro. From what I can tell, they have neither been to an encuentro, nor to a marathon. As for the internationality: all milongas in my home region will host dancers from France, Germany and Luxemburg because of our city’s situation in a triangle of three countries. Does this make an event with less that 200 mostly regional dancers an “international festival”?

Another case from last year: A couple of organisers who are specialised in big festivals and personally dance in a rather expansive manner visited their first encuentro milonguero. After that, they decided to organise one as well. Because of their lack of connections in the milonguero community, it was mostly visited by their regular festival- and milonga-customers, who are no milongueros. Do you think that this was a genuine encuentro? I just know, that the single participant who had traveled from afar because she had believed in the publicity was very disappointed. 

The same is happening in lots of places: organisers who want to make money or are just too lazy to describe their events properly, use popular and often quite wrong labels to attract customers.

Sure, there is no law against it and one can expect customers to inform themselves properly. And yes, experienced organisers can cater to different tastes, if they take their jobs seriously or ask for help from experts. But sorry, the above-described behaviour is just unsound business practise. 

I firmly believe that it is not enough to label an event in a certain manner and then stick to some general features in order to make it work. To deliver quality, you have to believe in what you are doing and share the philosophy of your desired customers. That is what makes tango events authentic, personal and good. I know the features of a marathon and I could surely organise one without making any major mistakes, but: I only have very few connections in the marathon scene and there are some aspects of marathons, that I don’t agree with. How could I deliver a great experience for everyone else? You have to know something intimately to create it and you should love what you sell.

In this I agree with many other organisers and business-people in general. Just recently, I visited an encuentro-marathon mixer in Barcelona and discussed the subject with friends. They are anchored in the marathon scene, but have started visiting encuentros. And they are observing the same phenomenon: organisers announcing events as “marathons” without being able or wanting to deliver what they promise. Because of this, Dany de Kay has recently published a brief “terminology of tango events”, to be found here.

At the time of publishing, I had already written the biggest part of this article. But when Dany published his list, I stopped working on it. I have now decided to post my “ABC of Tango Events” nevertheless, as it may offer insights from another perspective and because my blog is read by another clientele. The more we spread the idea of correct labelling, the more we can help organisers and customers to agree upon what the want from each other.

In order for you to understand the basis of my terminology, I will first define three general terms.


1. Los Codigos Milongueros
… are a set of behavioural guidelines recommended by organisers of what often is called “traditional” tango events. 
A short note: Let us not forget, that some of these codigos might the result of a very recent development. As far as I can tell, mirada & cabeceo e.g. might not have been used in the “época d’óro” - at least not everywhere. Men just walked up to their partners and asked them - or their mothers - for a dance. And how could the music be arranged in “tandas” when only one orchestra played live music at a milonga. Actually I believe the “codigos milongueros” to be a modern set of guidelines, that developed to cope with the inevitable chaos and misunderstandings that came with the tango-renaissance in the 80s and 90s.
However long they exist, this is what they boil down to:
- Preservation of the embrace throughout the dance.
- Respect for the ronda and other dancers: leaders cabeceo to enter the ronda, abstinence of movements that take up too much space or might disturb other dancers, constant movement counter-clockwise in one’s lane on the dance-floor.
- Respect for the personal space of everyone and equal activity of followers and leaders in the process of invitation: use of mirada and cabeceo.
- Promote of frequent exchange of partners, so that no-one is left out: clear dance-floor after one tanda, so that everyone can choose another partner.

2. Milonguero, Milonguera, Tango Milonguero
A milonguero or milonguera is a person who dances tango on a regular basis with a high level of commitment and will act upon the "codigos milongueros“. 
Some people relate the term “milonguero“ to a certain style of dancing, often limited to a small repertoire of typical steps and an "apilado“ (leaning) embrace. In my opinion, the term should not be narrowed in this way. General opinion agrees, that milongueros can have different and individual styles, varying from very traditional to highly modern. These styles are often influenced by the space available at their regular milongas. The milongueros of the packed milongas in the centre of Buenos Aires have obviously developed a style with small, rhythmic moves in contrast to their colleagues in the outer barrios, who’ve got huge dance-halls to move in. Even the embrace can range from a slightly open v-hold to a very closed chest-to-chest contact. In general one can say, that a milonguero dances tango de salón.
There are recent opinions who challenge the codigos-based definition by stating, that a milonguero does not necessarily agree with the "codigos milongueros“. In their opinion, the term “milonguero” would just describe a dedicated tango dancer. I don’t find this generalisation helpful. Most tango dancers are dedicated to the tango culture and there is a term to describe them: they are tangueros. To be a milonguero or milonguera implies a shared philosophy, a commitment to a set of values that helps define the community and its expectations.

3. Tango de Salón
For many years, this term has been signifying tango as it is danced in the milongas, the salons. It distinguishes social tango from the choreographed stage tango, the tango escenario. As social tango is always danced in a ronda with other couples, it makes sense to forgo movements, that would endanger the other dancers on the floor, such as high voleos, certain forms of ganchos or volcadas, sentadas, jumps, huge colgadas and the like. As the ronda requires the couple to adapt to the movement to the other dancers, it does not allow for pre-set figures or choreographies. Improvisation is of the utmost importance. 
Since the turn of the century, there has been the tendency to limit the term “tango de salon“ to a certain style: Tango Villa Urquiza. This was done in order to distinguish this more elaborate style from the supposedly very restricted “estilo milonguero“. But as I don’t believe that there is one “estilo milonguero”, I don’t see the necessity of constricting “tango de salon“ to such a narrow meaning either. I will go on using it as a generic term. When asked what he was dancing the late Tete Rusconi - a famous milonguero - would answer “tango de salón” I keep it as simple.

Let me now describe the different forms of tango events, as I know them. There are of course events, that have mixed features, but - as stated above - these traits will usually then be mentioned in the event’s description. For example: Our “Festivalito con Amigos” started out as a festivalito, a small festival. Later is was more clearly specified as a festivalito milonguero, but nowadays it is a pure encuentro milonguero, that preserved only one feature from its festivalito-days: short demo by a couple of our friends. 

So here finally goes my: 

ABC of Tango Events


Encuentro Milonguero
Definition: A meeting of milongueros. In Italy, these events might be called raduno", in France "rencontre“ or ”rendez-vous“. The term suggests a rather intimate setting in which people can socialise easily as opposed to the more anonymous festival atmosphere. (There can of course also be encuentros of non-milongueros, but in the last years, this terms was mostly used in the milonguero context.)
Duration: 3-5 days
Milongas/Dancing: Separate milongas, usually one in the afternoon and another one in the evening. The last Milonga is often called “despedida” (farewell party) and will usually take place on Sunday afternoon to allow the participants to return to their home towns on the same day.
Demos: Usually none
Music: traditional tango music in tandas and with cortinas presented by experienced DJs, often with international reputation, no live music
Classes: None
Booking: Several months in advance
Balance of gender or dance-roles: Yes
Separate seating of men, women and couples: Contrary to uninformed belief, only 50% of the encuentros use this set-up. Please enquire with the organisers or check here.
Participants: Aims to attract experienced dancers from all over Europe or the world, but might also have a smaller catchment area, depending on the connections of the organisers.
Number of participants: Approx. 80 - 300. (Recommendation: stay below 200 to preserve the spirit of an intimate encounter.)
Behavioural codes: The „codigos milongueros“ are promoted.
Typical examples: Abrazos (UK), Les Cigales (France), Yo Soy Milonguero (Italy)

Festival
Definition: Festivals are important events with a comprehensive programme, often hosted at spectacular or big venues. The term "international“ might be added to suggest its significance. 
Duration: 3 days or more, some festivals last up to a week
Milongas/Dancing: Separate Milongas, at least one per evening, usually a formal ball on Saturday
Demos: Shows by the teaching couples and guests of honour
Music: Tango music presented by experienced DJs, often of international reputation, often one or more orchestras.
Classes: Numerous classes by the teacher couples, additionally there might be private classes, lectures, discussions, art presentations. (Recommendation: please call your event a festival, if you plan on inviting more than 2 teachers couples of a certain recognition. Inviting the local teachers to do a beginners class alongside the Argentine guests does not turn your workshop weekend into a festival.) 
Booking: Classes and or festival passes are usually booked in advance, milongas/balls might sometimes be payed over the counter.
Balance of gender or dance-roles: No
Separate seating of men, women and couples: No
Participants: Dancers of all levels and styles, sometimes additional spectators, who come for the shows and concerts. 
Number of participants: A lot. (Please do not call your event a festival, if you expect much less than 200 dancers. Large festivals might host up to 2000 participants, in the past even more. If your events is much smaller in scale, why not call it Festivalito?)
Behavioural codes: Often none, which is why experienced dancers often shun festivals. But it does not have to be that way. Why not encourage the use of the „codigos milongueros“ to prevent the chaos, that often comes from an in-homogenous mixture of participants? At least those codigos that refer to the behaviour on the dance-floor would help a lot and might stop the decline of festivals in the customer’s favour.
Typical examples: Tangomanía (Netherlands), Ostertango (Switzerland), Tarbes en Tango (France)

Festivalito Milonguero
Definition: Basically the term describes a small festival - less participants, less teachers, a downsized programme. But when specified by the expression “milonguero“ it is usually an encuentro milonguero with some classes and a demo. This is what I am referring to in this description.
Duration: Usually 3 days
Milongas/Dancing: Separate milongas, at least one per day, sometimes additional afternoon Milongas
Demos: Usually a short improvised demo of close-embrace by the teaching couples or guests of honour
Music: Traditional tango music in tandas and with cortinas presented by experienced DJs, no live music.
Classes: A few classes by 1-2 teacher couples, additionally private classes or privatandas (privates of the duration of one tanda), sometimes practicas
Booking: Usually several months in advance, classes might be booked later
Balance of gender or dance-roles: Mostly. I strongly recommend to stick to this feature, as the general audience expects this feature to come with the label.
Separate seating of men, women and couples: Usually not.
Participants: Aims to attract experienced dancers, in particular those who want to develop their skills and knowledge, but might also be open to less experienced dancers in order to integrate them into the community. A festivalito can nevertheless can be composed of a very international, highly-skilled crowd, depending on the “pull“ of the organisers, DJs and teachers.
Number of participants: 80 - 200
Behavioural codes: The "codigos milongueros“ are promoted and expected.
Typical examples: Festivalito Rural (2010-15 in Slovenia), Embrace Norway (Norway), Pequeña (Germany)

Marathon
Definition: Non-stop dancing over a longer period, typically in a more informal setting.
Duration: Usually 3 days. There seem to be other formats as well. A 12-hour Milonga might also be called a marathon, but I am not sure, if marathon folk would find that appropriate. Dany de Kay’s terminology speaks of 3 days.
Milongas/Dancing: The milongas blend into each other, usually interrupted by short breaks in the morning hours or during the shared meals.
Demos: None
Music: Usually traditional tango music presented in tandas and with cortinas by experienced DJs, but some Marathons may be also open to non-tango music or modern tango recordings. Please check with the organisers. No live music.
Classes: None
Booking: Usually several months in advance
Balance of gender or dance-roles: Yes
Separate seating of men, women and couples: No
Participants: Depends on the connections of the organisers, but aims to attract an international crowd of experienced dancers. 
Number of participants: Approx. 80 - 300. (From what I can tell.)
Behavioural codes: Depends on the organisers and participants. At some marathons mirada & cabeceo are encouraged as well as the clearance of the dance-floor during the cortinas, but at other events, people seem to dance several tandas with the same partner. Depending on the experience of the dancers, the ronda will certainly be civilised, but some more higher-risk movements are to be expected.
Typical examples: La Tosca (Italy), High Noon (Germany), Bergen Tango Marathon (Norway)

Milonga
Definition: A single tango event during the afternoon or evening. Can be a recurring or a one-time-only event.
Duration: Approximately 3-5 hours
Milongas/Dancing: Single event
Demos: Usually none - except in many Buenos Aires Milongas, where demos can be seen on a regular basis.
Music: Depending on the taste of the organisers, please check with them.
Classes: Usually none. In the USA, pre-milonga classes are popular.
Booking: Usually not required
Balance of gender or dance-roles: Usually not
Separate seating of men, women and couples: Usually not. There are a few Milongas in Buenos Aires, Italy and France that use that special set-up, but they are definitely exceptions.
Participants: Depends on the connections of the organisers 
Number of participants: 2 - 200 or even more
Behavioural codes: Depends on the organisers and participants. More and more organisers encourage the “codigos milongueros”, at least those related to the behaviour on the dance-floor.
Typical examples: Any milonga in your home community

Milonga Weekend
Definition: A series of connected or un-connected milongas on one weekend. Either by one organiser or by several. A recent variation is for a bunch of friends to “band together” and visit several local milongas. Can be recurring or a one-time-only.
Duration: 2-3 days
Milongas/Dancing: Separate Milongas
Demos, Music, Classes, Booking, Separate Seating, Number of Participants: See “Milonga”
Participants: Depends on the connections of the organisers, but because of the higher concentration of milongas on one weekend, dancers from afar are more likely to visit.
Typical example: Tangosommer Wiesbaden

Workshop Weekend
Definition: A special event, created around the visit of a teacher couple or workshops by local teachers.
Duration: Usually 2-3 days
Milongas/Dancing: Separate evening milongas, at least one per weekend, usually no afternoon milongas, as the classes will take place at this time of the day.

Participants: Mostly local and regional dancers of all levels
Number of participants: Depends on the local community and the "pull“ of the teachers

So, that’s it for the moment. I hope this list will help organisers and consumers to communicate and plan better.  

I might add more info later upon noticing that I have forgotten important features or entire forms of events. Do not hesitate to contact me with reasonable suggestions.
