Catá is the rhythm played during rumba, typically on a piece of bamboo or, nowadays, on a red LP jamblock. This rhythm can be adapted to various parts of the drum set as well. I use it for cool double bass patterns and also as a hi hat pattern for a time keeping pattern when there are congueros wanting to play rumba.

Here are the two catá patterns you'll see on the QuickTime video.
