How to practice

Start with a small answer pool. When your accuracy is stable, move to Balanced or Challenge.

Listen to two notes. First learn obvious contrasts like Minor 3rd, Major 3rd, Perfect 5th, and Octave.

Start with Major vs Minor. Use replay and compare when the color feels unclear.

Note recognition is hard. Use a small pool first. The octave changes, but the pitch class answer stays the same.

Listen for the color of the scale. Do not try to memorize every note at full speed.

5 minutes intervals, 5 minutes chords, 5 minutes notes or scales, then 5 minutes weak areas.

Use moderate volume. Ear training improves through clear, relaxed listening, not loud volume.
