Progressions

The progressions pianists play most, in all twelve keys.

72 pages: the jazz ii–V–I in major and minor with shell and rootless voicings, and the four pop progressions with voicings that barely move. Spelled the way the key spells them, and every chord links to its own page in the chord library.

Play it. See every name.

The free chord finder names whatever you play — on a MIDI keyboard, with the mouse or on your computer keys — with the same engine as Cadenza.

Or let the app follow you.

Cadenza names every chord you play, live, with the degree over each key — and writes what you played as sheet music. The core is free forever, on Mac and Windows.
