Chord & FretC7(#9) on guitar
On the guitar, six strings give the chord room to breathe — some positions use them all, others ask you to mute the lowest ones. In this position the bass is E and the shape sits at fret 1, ringing 3 open strings. Its hollow wooden body gives every chord a warm, natural ring that blooms and fades on its own.
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.
