I don't see this as a musical instrument anymore then one could consider a metronome an instrument. This is a tool that you can use to experiment with and practice and you don't necessarily need a whole big band to back you while your practicing. This would be extremely useful for things like learning improvisation where its very helpful to have a beat as well as some sort of chordal support.
