PolyNome is used by the world's top musicians including Peter Erskine, Virgil Donati, Chris Coleman, Vinnie Colaiuta, Dave Weckl, Dennis Chambers and Will Lee.

“PolyNome is great for teaching, practicing and rehearsing. The rhythmic and the subdivision possibilities are endless. Plus, this is the only metronome I’ve used that you can actually LEARN from. Simply brilliant.”

Peter Erskine (Steely Dan, Weather Report, Kate Bush)
