Drum beats are as varied as cuisine or the dialects of a language and are literally too numerous to count. At a tribal/cultural level, beats tend to be associated with the regions they originate from, and since beats and dance are so closely related, each beat will have its own sub-set of associated dances as well. Africa and India in particular both have rich histories of rhythmic music-making which are distinct from other traditions, but within themselves can boast hundreds of sub-genres.
