I have to add my bit about Kung Fu and music as well.
I've been playing drums for about 12 years...
After studying Kung Fu, my stamina for playing has increased drastically. Just like soft and hard stikes in Kung Fu, you have soft and hard strikes in percussion.
The composition of songs is virtually identical (in theory) to that of forms. Simply put, playing a song from start to finish is a sequence of movements - that must be mastered in order for the song to come out right.
Each member of the band working together would be comparable to a four-man matching set (if such a thing exists). Must be in complete unison.
I've found the two arts to be alike in so many ways. And the way they compliment each other is amazing.

Then, while playing the drum during Lion Dance, I get to combine both...

Good thread.

Peace.
