Flip-a-rhythm is a collection of 144 rhythms in two books: just turn over book 1 to find book 2. Each four-bar rhythm can be combined with any of 36 alternatives, giving over 5000 possible combinations in the two books! Book 2 contains more difficult 3/4 time rhythms. Always keep a regular rhythm (count, beat or sway). Play rhythm duets, add a tone to make a tune, or count out loud while beating a line with each hand.
