Harmonize: Ear Trainer & Pitch

About Harmonize: Ear Trainer & Pitch

🎵 Ear training that sticks — 15 games for intervals, chords, rhythm and playing melodies by ear. Free to start, no account needed.

Most ear trainers ask you to pick the answer from a list. Harmonize asks you to *make* the sound: slide to harmonize against a reference tone, play a melody back on a keyboard, tap a rhythm. Producing the interval yourself is what makes it stay. Train with the cute mascots Ebifurya and Kakifurya.

▼ 15 games • Double Stop — harmonize two notes: unison, octave, perfect 5th/4th, major/minor 3rds and 6ths (8 categories) • Chords — real 3–4 voice chords, unlocked as you collect stars • Moon — the reference tone fades away; harmonize from memory alone • Low Register — bass instruments, where intervals are hardest to hear • Trill — train the speed and evenness of your trill • Ear Copy — listen to a melody and play it back on the keyboard (9 categories, 129 levels) • Sight Reading — read notes on the staff and play them on the keyboard (9 categories, 180 levels, 1,020 exercises) • Rhythm — tap the offbeats with the metronome: 6 meters from march to sixteenths × 8 sound packs • Polyrhythm — two hands, two pulses at once • Mimic Drum — call and response: hear a rhythm, drum it back • Takoyaki — a memory game where the pairs match by pitch • Scales — major, minor and the church modes • Arpeggio — chord arpeggios in just intonation • Goldfish Scoop — tell the goldfish apart by their tone • Silent — no sound at all: count the seconds with your internal clock
