I think I’ve figured out why I rarely get anything out of musicality classes: They’re not usually taught by people that truly have learned, studied and practiced music.
Understanding music and contextualizing tango music is fundamental to teach about the music itself. Unfortunately, there’s a lot of young teachers out there that are fanatic to the point that they have not (yet?) danced anything else in their life and do not know much more music besides tango. This makes their teachings lack perspective and thus, failing to reach the entire class/audience.
Next time you go to a musicality class, make sure you’re not going to a “let me show you what move/steps I do when this type of stuff comes up in music“. The good news is that it’s very easy to realize when you are at either situation.
Musicality development is inherently personal and everyone needs to go through the individual process themselves. What a teacher should be able to give you are the tools for that. Not just share the end result, ie, a step/move, with you.
