Arpeggio · D°7 · Piano
The D°7 arpeggio is D – F – A♭ – B — chord tones 1 ♭3 ♭5 ?. D°7 is passing chords between diatonic chords, and as a 7♭9 without its root; its sound is symmetrical, restless. Below, every D, F, A♭, B on the two-octave keyboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.
