Chord & FretC7(#9) 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 sits at fret 1, ringing 3 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 – D#Formula: 1 – 3 – 5 – b7 – #9In 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: Blues, rock and soul with an intense sound.
