Piano with chord voicings for songwriters

Updated November 10, 2026. How we check these numbers

Quick answer: open the Piano tab, tap one of your song’s chords at the top, pick a voicing, and play the lit keys. Tap Play along to hear the band while you play.

Your chords, lit up

The chords at the top come from the progression on the Jam tab, so the piano always matches the song you’re writing. Tap one and its notes light up amber on the keys, with the chord name and notes in the readout.

Voicings a hand can reach

Six voicings, all kept within one hand: root position, both inversions, add9, the seventh that fits the chord, and sus2. Inversions are the easiest way to move between chords smoothly; add9 and sus2 give the shimmer you hear on a lot of modern ballads.

Built for fingers, not a mouse

Keys are wide and tall, the keyboard follows the chord you pick, and arrows move it up or down an octave. Turn on sustain for a softer, ringing sound.

Frequently asked questions

Are the keys big enough to play?

Each white key is about 48 points wide, roughly double a typical phone keyboard, so three fingers fit on a chord. The keyboard glides to whichever chord you pick.

Which voicings are there?

Root position, first inversion, second inversion, add9, seventh (major, dominant or minor to fit the chord) and sus2. Each fits under one hand.
