Chords, progressions, piano, and ukulele

Hear and see every chord in your song on guitar, ukulele, or piano, explore the chords in your key, and try classic progressions or generate new ones.

The Songcraft team · Oct 24, 2026

Songcraft recognizes the chords in your song, shows you how to play them on guitar, ukulele, or piano, and plays them back so you can hear the progression. The Chords tool lays out every chord in your key, and Progressions has classic progressions and standards to try, plus an idea generator for something new. All of this is free, and saving progressions and custom tunings are part of Pro.

See and hear a chord

Hover over any chord in your song (or tap it on a phone) to see its chart. Click the chart to hear it. For guitar and ukulele, the arrows step through other shapes for the same chord, and the lock uses the shape you picked everywhere in the song.

Songcraft reads chords however you write them, so C-7, Cm7, and CΔ7 all work, along with slash chords and extensions.

Progressions follow your song's key, and you can switch keys from the menu at the top.

Change the key or transpose
