Tired of stuffy ear training tools? Paging Dr. Bossa!

Dr. Bossa plays minor seventh chords in a random order. This allows an improviser to play along to a backing track that's constantly shifting, forcing them to train their ear to follow Dr. Bossa's mystical harmonic path.

Users can view the name of the chord if need be, but Dr. Bossa's method at its strongest when the "HIDE CHORD" button has been depressed. This will force the user to use their ear to follow the chord, allowing them to develop their harmonic response time.

So grab your axe, press that "START/STOP", button and jam out—doctor's orders!
