How to play C13♯9 on guitar
The most common way, the first shape above: your ring finger on the low E string at the 8th fret, your middle finger on the A string at the 7th fret, your middle finger on the D string at the 7th fret, your little finger on the G string at the 8th fret, your little finger on the B string at the 8th fret and your index finger on the high E string at the 6th fret.
From the low E string 8 7 7 8 8 6 (x: not played, 0: open)
An easier C13♯9
The full shape is a barre chord, hard at first. This one needs no full barre and sounds much the same: your ring finger on the low E string at the 3rd fret, your index finger on the D string at the 1st fret, your little finger on the G string at the 3rd fret and your middle finger on the B string at the 1st fret. Let the A and high E strings ring open.
