Chords & Intervals.

Every melody is built from intervals; every chord from stacked thirds. Hear them, learn the song that lives inside each one, see how to play it on your instrument — then train your ear on one at a time and reveal the answer when you're ready.

Train your ear — intervals

One interval, played from a random note. Name it in your head, then reveal it.

Play one, sing it back, work out what it is — then check yourself.
