Can you play what you hear?

Choose an audio track for playback. Each track begins with the tonic chord and a 2-bar count-in. There are 3 patterns on each track. Each pattern plays, followed by empty measures during which you echo (play back) the exact pitch and rhythm you hear. The pattern is then repeated.

1. You will hear only the tonic (I), subdominant (IV), or dominant (V) triads of the key.
2. Playback the series of triads that you hear.
3. Click an audio track to begin. 
4. The audio tracks are in 4/4 time.
