Quick Notes:

1. You will need to use an external speaker via bluetooth or headphone jack. The volume will need to be slightly high in order to get a proper interval comparison.
2. I strongly urge you to use a metronome. Set your metronome between ♩= 84 to 104
3. Press the play button at the top of the exercise. Doing so will start the drone.
4. Ignore the blue tracker. It is not synced with the exercise… yet. When the blue tracker reaches the end, the drone will stop.
5. Stop the metronome if there is a specific interval you want to work on.
