Clave (pronounced "clah-vay") is both a rhythm and an instrument. The "son clave" rhythm is the fundamental rhythm in salsa music and has two main variations: the "3-2 clave" shown here, and the "2-3 clave" which has the two bars in the reverse order. The choice of 2-3 or 3-2 depends on the music's melody. It may start or stop during the music but will not change from one form to the other in a single piece.
