Interval Study

Two pitches, and you name the distance between them. Switch between on staff, where you read the interval, and by ear, where you only hear it — the same drill either way, which is the point: it's ear training and sight-reading in one tool rather than two that disagree about difficulty.

You also choose how the two notes arrive: ascending, descending, or together as harmony. Descending intervals are the ones most people are quietly bad at, and a harmonic second is a different experience from a melodic one.

Four levels. The first two ask for size only — thirds, fifths and octaves, then every step from a second to an octave. The last two want quality as well as size: thirds, sixths and the perfect intervals first, then every interval within an octave, tritone included. The clef is yours — treble, bass, alto or tenor.

It's free and needs no account, and it doesn't end on its own — it keeps handing you intervals until you stop. If you're signed in, answers are saved to your progress in batches of ten.
