Can you play what you hear?

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.           

Each audio track begins with the tonic chord followed by a 2-bar count in. There are 3 patterns for playback. Each pattern (repeated twice) is followed by empty measures during which time you should repeat that exact pitch and rhythm that you hear.
