Chord progressions in D major in inversions, on mandolin
A progression in D major loops, strummed the way the app strums it, each chord in inversions — close-position triads in root position, first and second inversion, voice-led from chord to chord — 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.

The chords of D major
D major is D E F♯ G A B C♯. The chord on each degree: D (I), Em (ii), F♯m (iii), G (IV), A (V), Bm (vi), C♯° (vii°). The loop draws from the 6 you can rest on — D, Em, F♯m, G, A, Bm — one or two chords with D in front, or four from the progressions below. Every chord is also on the nest explorer, with its shapes.
