This drum sounds lovely! Clear, soothing tones. Each tongue has a numbered sticker that is meaningless to me. Included are strips of equally meaningless numbered stickers. 1,2,3, three with a dot above it, 4,5,6,7, seven with a dot beneath it, etc.Why not musical notes? I'm using a tuner app to figure out what the tones are so we can tap out songs. Each tongue is adjustable for tuning, which is nice.That said, it sounds beautiful even when you tap randomly. The mallets are nice and bouncy, and you even get 4 little finger pads to play it that way. The metal has a nice hammered finish and is a good thickness, not flimsy.This is a nice, mid-sized and mid-priced tonal drum. Good value for what I paid. It doesn't feel "cheap", and none of the notes buzz or rattle.
