So I’m a musical retard but I think I figured it out. Musicality is simply understanding the relationship between different notes in tango music.

There are really only 2 kinds of notes. I’ll call them “heavy” and “light”. And the organization of different tango music genres, typically organize the heavy beats of a certain way.

• Tango (steady walking beat): 1…2…3…4
• Waltz (swaying beat): 123.123.123
• Milonga (kinda fast and choppy): 1…341…341
• (warning: these are not how musicians would explain the beat placements but I explain it this way for non-musically trained listeners)

The light beats are basically all the lighter beats played between the heavy beats. They vary between different orchestras and different songs (which open doors for your musicality). The skill of your musicality refers to your ability to “notice” (and perhaps dance) the light beats while still following the heavy beats. Without this skill, it would appear as though you were dancing the same way to every since song (since the heavy notes are generally the same in all songs).
