Arpeggio · A7 · Guitar
The A7 arpeggio is A – C♯ – E – G — chord tones 1 3 5 ♭7. A7 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 A, C♯, E, G on the fretboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.

Common questions
A – C♯ – E – G. As chord tones: 1 3 5 ♭7. Played one after another instead of together, that is the arpeggio.
A7 is the V chord — the engine of every cadence, and every bar of a blues. Its character is tense, pulling toward its resolution.
A Mixolydian (A B C♯ D E F♯ G) — the arpeggio is the skeleton of that scale, so practise them together.
Start on the root A on the low E string at fret 5 and play E-string fret 5, E-string fret 9, A-string fret 7, D-string fret 5, D-string fret 7. Then play it descending, then in eighth notes with a metronome, then over the the V chord — the engine of every cadence.
