Train your ear by singing, not guessing.
There are nine interleaved games here, built for people who write and produce music. You sing bass lines back to a click, hold a harmony against another voice, and hear chords as functions. Every round gives you real notation and live pitch feedback, and the schedule adapts to keep you at the edge of your ability.
Chords & progressions
Hear harmony as function: label loops, sing bass lines, audiate from the page.
- Bass Hunter trains bass-line extraction.
- Function Feeler trains functional hearing (scale-degree labels).
- Real Song Fragment trains tonic inference + transfer to real music.
- Audiation First trains notation → inner hearing → voice.
Melody & part singing
Hold your own line: mirror melodies, sing harmonies, pads, and rounds.
- Melody Mirror trains melodic working memory + pitch matching.
- Harmony Lines trains reading + holding a harmony line against another voice.
- Interval Echo trains mental transposition by diatonic interval, by ear.
- Pad Singer trains chord-tone selection + nearest-tone voice leading.
- Round Canon trains part independence under interference.
Built on how skills actually stick
Every round is a test rather than a review. You produce the answer with your voice, get graded note by note on the staff, and retry until it lands. Games interleave, keys rove, scaffolds fade, and weak skills come back on a spaced-repetition schedule. That is the testing effect, desirable difficulties, and audiation-first teaching doing the work.
