Good but limited, especially for price
The exercises are in half steps only as apposed to diatonic or linear harmony, which if you know anything about singing and ear training, is only a small piece of the puzzle. Id like to see: diatonic arpeggios, maybe some songs with the pitch bubbles for more accuracy, and most importantly vocal harmony practice. You could play two notes and score the student on one of them. All in all its still a great tool!-mike
