The art of drumming is one of the oldest forms of music and music communication. The idea of using drums for rituals and celebrations goes back to early recorded history, across a range of cultures. The playing of these instruments would have included call and response with distinct rhythmic phrases from cultures such as Africa, Latin America, and Indian. In western music some of the rhythms heard in other cultures can be identified as polyrhythms. The book introduces rhythmic concepts that can be used by drummers or any musician to expand his or her rhythmic repertoire for improvisation or composition. It combines concepts taught to the author by Alan Dawson with South Indian Konnakol syllables. It is a comprehensive study of polyrhythms that allows drummers to delve deeply into modern rhythmic concepts.
