This is your Suzuki M-37C Plus on screen: 37 keys, F3 to F6, low end at the mouthpiece. Type a chord progression, pick a scale, or run a drill, and the keys to press light up. Tap any key to hear the real instrument.

Explore

Type a progression (Am F C G, or Roman numerals like I V vi IV in the current key) or a melody (C D E C) and press Set, or tap the chord chips, or hit Random. Then Play steps through it in time: each chord's keys light with fingering numbers, and the next chord ghosts in one beat early so your hand can move.

Chords

A chord finder: any chord symbol, with inversions and octave placement, and every place it fits on the keyboard.

Drill

Short practice rounds toward the goals below: find notes, play chords, play a progression in time, play back a melody. Answer on screen, on the computer keyboard, or by playing the melodica into the microphone.

Options

Labels fade from every key, to C and F landmarks, to none. Names switches note names to scale degrees. View rotates the keyboard the way it looks in your hands (automatic on a phone in portrait). Pick a Register to zoom in on one part of the keyboard, which makes the keys big enough to tap on a phone. Air is breath: it darkens and softens the sound like blowing less.
