How this interval trainer works
Press play, hear two notes, and name the distance between them — a third, a fifth, a seventh. Ten questions per round, instant feedback after every answer, and a difficulty ladder that starts with wide, easy-to-hear contrasts and narrows as you improve. No account, no install; it runs in the page you're reading.
Why this one trains you differently
Most interval drills play two notes in a vacuum. That teaches you a fact about a sound. But an isolated interval is a fact — a note in a key is music. Here every question lives inside a musical context, so the skill you build is the one you actually use when you transcribe a melody or find a harmony by ear: hearing what an interval means where it sits, not just how wide it is.
What to do when you plateau
Interval naming usually stalls when the sound is recognized but not yet felt in a key. That's the cue to switch to the scale degree trainer — same sounds, asked the way music actually asks them. The intervals lesson explains the connection, and the full drill ladder runs from "up or down?" to tapping back whole phrases.
