Train your relative pitch by harmonizing tones with cute mascots. 7 languages.
🎵 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!
