Chord & FretC7(b13) on electric guitar
On the electric guitar a chord needs only a few clear notes — the amp sustains them and fills the space, so you mute the strings you are not playing and let the tone carry the rest. In this position the bass is E and the shape runs from fret 1 to 2, ringing 2 open strings. Plugged into an amp, each chord sustains for as long as you hold it, and the tone — clean or driven — shapes the whole sound.
Notes on C: C – E – G – Bb – AbFormula: 1 – 3 – 5 – b7 – b13In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
Where to use it: A dark resolution, especially to a minor chord.
