Ear training, play by ear, intervals, chords and rhythm — 15 games in one app.
Warm up your ears before singing, band, orchestra, choir, guitar or piano practice.
Harmonize teaches distance between notes by making you rebuild what you just heard. Your mic picks up your voice or instrument and shows how far off you are, in cents. No music theory needed: a friendly shrimp plays the example, and you copy it.
■ Build the interval
- Double Stop — add a second note on top of a reference: octave, perfect fifth, major third and more
- Chords — take one role inside a three-note chord and hold your part
- Moon — a slow, low-gravity version of Double Stop for advanced ears
- Low Register — the real bass range, so low that a phone speaker cannot reproduce the fundamental; you read the pitch from its overtones
- Trill — hold one finger down and press/lift with another. 6 fingerings x 36 exercises
■ Read the score
- Sight Reading — read the notes on the staff and answer on the two-row keyboard. The white keys are labeled with their note names, so you can count lines and spaces even if sheet music is new to you. 9 categories, 180 levels, 1,020 exercises
■ Rhythm
- Rhythm — tap along with the scrolling score
- Polyrhythm — two different pulses at once, one per hand
- Mimic Taiko — call and response on Japanese drums. Hear a pattern, play it back
- Silence — no sound at all. Measure time with your internal clock
■ Listen and remember
- Play by Ear — reproduce the melody you heard on the keyboard. 9 categories, 129 levels, 516 phrases
- Scales — trace a scale one note at a time
- Arpeggios — hear a broken chord and follow it
- Memory — a sound version of concentration: find the two takoyaki that ring alike
- Goldfish Scooping — memorize each swimming fish by its note, then scoop them in the order given
