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