Hi all, I'm working on a birthday gift for my fiancé and need some help. I want to make a music box with a specific tune from his favorite game, and bought the Kikkerland 15-note kit. I have experience reading/writing music, but realized after the fact that the song has some parts that walk down chromatically for three notes, and I can't figure out if it's possible to make them work! Is there a way to fake/transcribe enough to get around the "no black keys on the piano" format of a 15-note, or should I upgrade to a 30 and try it there? Thank you!!
