Chord & FretC7(b9) 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(b9) voicing the bass is C and the shape runs from fret 2 to 3, ringing 1 open string. Plugged into an amp, each chord sustains for as long as you hold it, and the tone — clean or driven — shapes the whole sound.
