[wwcuswwy] De Bruijn chords

Identify a collection of chords and play the de Bruijn sequence of all, say, 3-chord sequences of them, perhaps arpeggiated like Prelude in C.  Perhaps I ii iii IV V vi V7 and inversions.  This should be easy.

The minor key version simply substitutes III7 for V7.

De Bruijn sequences are cyclic, so the song can loop forever.
