Harmonize: Ear Training

🎵 Harmonize is a fun ear-training game where you sharpen your relative pitch together with the cute mascots Ebifurya and Kakifurya. Against a reference tone, slide your finger to “harmonize” musical intervals — unison, octave, perfect fifth/fourth, major/minor thirds and sixths — and match them exactly. The closer to 0 cents, the higher your score. Collect three stars to move on to the next stage! ▼ Simple to play • Listen carefully to the model tone • Slide up and down to match the pitch • Tap GO to be judged — see how many cents off you were and your stars ▼ Modes • Double Stop: harmonize two notes (8 categories) • Chords: real 3–4 voice chords (unlock by collecting stars) • Moon: a memory mode where the model tone fades away — harmonize from memory alone • Rhythm: tap the offbeats along with the metronome. 6 meters from march to sixteenth notes × 8 sound packs incl. drums. Replay your rhythm and compare it with the example on the result screen • One-Shot Challenge: 5 weekly questions, the model plays only once — compete on the online weekly leaderboard • Tutorial: guided practice, perfect for beginners ▼ Thoughtful features • 14 instrument tones (piano, organ, violin, trumpet, shakuhachi, flute and more) • Adjustable A reference (440–446 Hz) • Note-name notation: English / German / Japanese / Italian • Toggle background animation and guide bubbles • Per-voice volume and vibrato • Rhythm timing calibration — accurate judgement even with Bluetooth earphones • Optional "Remove Ads" in-app purchase ▼ 7 languages English, 日本語, Français, Deutsch, Español, 简体中文, 한국어 — switch anytime in Settings.
