Chord progressions in D♭ major, on mandolin
A progression in D♭ major (C♯ major) loops, strummed the way the app strums it, each chord's shape lit on the mandolin as it sounds and the whole key drawn under it. Play over it; N draws a new loop. Nothing listens here, in the browser or in the app — there, Explore suggests what to play over the loop, and leads on to the games that do.
