Ear Training L3 - The Moons

The Moons is a drone-based ear training app for exploring and internalizing chords and chord progressions. It presents the seven diatonic chords as an interactive moons diagram where you can tap individual chords in a key and hear them against a sustained vocal drone. To see how your ear training is coming along, the app includes a fun and challenging test mode.

How it works:
Chords Mode: Start the drone, then tap spheres of the moons to hear chords. Use the arrow selector to shift to the closest inversion either up or down. In male choir mode, the radio buttons above sound melody tones. In female choir mode, the same buttons trigger a bass tone below.

Chords Test Mode: Start drone, choose levels, then begin. Listen to the chord played, click the corresponding moon to select, then press the checkmark to commit. Once you’ve committed, or when the timer runs out, you’ll receive feedback as to the accuracy of your selection.

3 levels in Chord Test Mode:
1) Root position chords
2) 1st Inversions
3) 2nd inversions
(test individually or in combination)

Progressions Mode: Start the drone. Select a chord then press “Add” to add it to the progression. Repeat up to four times. Press play to hear the progression. The slider below the progression speeds up or slows down the tempo. Activate “Loop” to loop the progression.

Chord Progressions Test Mode: Start drone, choose levels, then begin. Listen to the chord progression played, click a series of 3 corresponding moons, first selecting then commiting each of the chords. Once you’ve commited, or when the timer runs out, you’ll receive feedback as to the accuracy of your selections.

4 levels in Chord Progression Mode:
1) Simple Cadences
2) Deceptive Cadences
3) Unresolved Progressions
