How it works: Add a Bordun (pitched drone on barred instruments) and one or more Percussion ostinati. Click a percussion cell to cycle empty → hit → rest. For the bordun, pick a pitch (or a do+so chord) from each cell, or drop in a preset. Each part can be a different number of bars — shorter parts loop under the longest. Turn on Lyrics to type words under any part. Export the whole score, or each part on its own for flashcards.
