Ear Training · Free Tool
You already hear the difference. Naming it instantly is what separates transcribing a part in ten minutes from losing an afternoon to it.
Two tests, one game. Train your ears on intervals — 2nds through the octave, ascending, descending or harmonic — and chord qualities — major, minor, diminished, augmented and 7ths. Earn XP, level up your rank, keep a daily streak. Warm Rhodes-style synthesis, in your browser.
space play, and after an answer it deals the next set of notes — a miss costs one extra press that replays what it actually was, so you never move on without hearing it · R root · N skip · 1–9 pick answer · H reveal. Adaptive widens the set after 2 right in a row and narrows after a miss. Tip: sing the two notes back — it's the fastest way to lock a harmonic interval.
Ears this good usually end up writing for games and film — where half the soundtrack isn't notes. Twelve hand-picked sounds from DreadScape: creature vocals, impacts, drones, stingers and UI. Same masters as the paid pack, no watermarks, free for commercial use.

Intervals. A chord is a stack of intervals, so the interval test builds the thing the chord test then asks you to hear several of at once. If chord quality feels like guessing, drop back to intervals for a week and it usually stops being guesswork.
Ascending plays the lower note then the higher one; descending plays them the other way round; harmonic plays both together. They are genuinely different skills — most people find descending intervals hardest — so the trainer scores them separately and Mixed rotates between all three.
It plays the bottom note of the pair on its own. An interval is a distance between two notes, not a sound of its own, so naming one means knowing where you are measuring from — the Root button is that fixed point. Play it, hum it back, then play the question and listen to how far the other note sits from it. In a descending interval, that bottom note is the one you hear second. Leaning on it is not cheating: judging a note against a root you already know is how people actually work things out by ear. Once it starts feeling easy, set Key context to Cadence — the trainer then plays a short chord sequence first, so the question sits inside a key instead of floating on its own.
