Chord & FretC7(b9) 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(b9) voicing the bass is C and the shape runs from fret 2 to 3, ringing 1 open string. Its hollow wooden body gives every chord a warm, natural ring that blooms and fades on its own.
