Start with the idea

Two hands. Two jobs.

01 · LEFT HAND

Choose what to play

Raise a gesture to choose a place in the key. Think of each shape as a sound button, not a music theory test.

02 · RIGHT HAND

Start and shape the sound

The right hand is required. It starts the left-hand chord, chooses its voicing and octave, and controls volume and filter.

03 · BOTH HANDS

Match the chart

In Guide mode, match both target shapes while the beat and chord chart move through the song.

Left hand · What to play

Copy the exact finger combination.

TipStart with one finger. Once you hear the change, try two, then three.

Right hand · How it sounds

Give the chord a character.

1 finger
2 fingers
3 fingers
4 fingers

From simple to rich

One non-thumb finger is the root-position chord, two is first inversion, three is a seventh chord, and four is dominant or diminished seventh. Extending the thumb lowers the result by one octave. Move higher for louder, lower for softer, and tilt inward for more filter or outward for less.

The right hand is required: the left hand chooses the chord, and the right hand starts and shapes its sound.

Practice a whole song

Follow the score. Keep your freedom.

Guide mode keeps the complete lyric line visible, highlights its current scored segment, draws the exact left-hand target and uses any clear right-hand shape to open the sound.
