Arpeggio · B♭7 · Piano
The B♭7 arpeggio is B♭ – D – F – A♭ — chord tones 1 3 5 ♭7. B♭7 is the V chord — the engine of every cadence, and every bar of a blues; its sound is tense, pulling toward its resolution. Below, every B♭, D, F, A♭ on the two-octave keyboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.
