How to play C♯13♭9 on guitar
The most common way, the first shape above: lay your index finger flat across the three strings from the D to the B at the 3rd fret, your middle finger on the A string at the 4th fret, your ring finger on the G string at the 4th fret and your little finger on the high E string at the 6th fret. Don’t play the low E string.

An easier C♯13♭9
The full shape is a barre chord, hard at first. This one needs no full barre and sounds much the same: your little finger on the A string at the 4th fret, your ring finger on the G string at the 3rd fret and your index finger on the high E string at the 1st fret. Let the D and B strings ring open. Don’t play the low E string.
