“Music, martial arts and dance have the same underlying roots: rhythm, movement, timing, the manipulation of volume or intensity, expression, and hopefully, exploration, improvisation, and creativity. Music uses all of the above with sound, dance with physical manifestations, and martial arts with physical manifestations against an opponent. Played with others, music requires coordination, adaptation, and flexibility relative to others. So do dance and martial arts.”
