Chord & FretC7(#5) 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 C7(#5) voicing the bass is E and the shape sits at fret 1, ringing 2 open strings. Its hollow wooden body gives every chord a warm, natural ring that blooms and fades on its own.
