Chords & Intervals.

Every melody is built from intervals; every chord from stacked thirds. Hear them, learn the song that lives inside each one, and see how to play it on your instrument. Everything is named and playable: move between sounds until the colour becomes familiar.

a musician's way to learn them

Choose two neighbouring rows and alternate them. Sing the upper note before pressing melodic, then listen to both together as harmony. The name, sound, song and fingering remain on screen together so the ear builds a useful connection instead of chasing a mark.
