Regardless of whether you understand whats going on (or even how this video of a DVD tries to show you how to perform good percussion solos) - just listening to the solos are great! For those who dance On1 - , listen very carefully to the music here (because the clave and rhythm is isolated for you to hear). This is really what we (On2) dancers use in the music to dance to. You might say it sounds like cha-cha - well....you are correct, but you dance Cha-Cha On2, and the same instrumental fundamentals of clave apply to Salsa/Mambo. That's why, people who dance salsa on2 can easily dance cha-cha correctly (and vice-versa) because all you are doing is replacing the pause with a cha-cha-cha step. There is no cha-cha On1 - it doesn't make sense because the cha-cha-cha happens on 4-and-5 and 8-and-1 in the music (just listen to it) - meaning your break happens on 2-3 and 6-7... just like in.... Salsa on2 :-).
