Are you a kind of person who just can't stop tapping your fingers on the furniture trying to reproduce a favorite melody? This seems to be annoying...
Why not create electronic gloves which will create the music while you are tapping on the dining table for example? Each finger on the glove will be mapped to a different note with different musical instrument tones for you to choose from. There could be also a couple of distinct background rhythms and pre-recorded songs.
