Arpeggio · C7 · Guitar
The C7 arpeggio is C – E – G – B♭ — chord tones 1 3 5 ♭7. C7 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 C, E, G, B♭ on the fretboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.
