Chord & FretC7(#5) 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 C7(#5) voicing the bass is E and the shape sits at fret 1, 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.
