Rumba is probably the most popular music to come out of Cuba and has since spread to other parts of the world as the quintessential Latin music. In rumba, several instruments are used.
The claves (pronounced clah-vay) are two short hardwood sticks that are banged together, and play an interlocking rhythmic pattern with palitos, which are longer hard sticks that beat against the side of a drum.
There are usually two conga drums of two different pitches that also play in the interlocking rhythms (polyrhythms). A conga is a tall drum played with the hands while standing up.
With most rumba music there is also a vocalist singing over the intricate rhythms about any number of topics from love to neighborhood events.
