How to play C9♭5 on guitar
The most common way, the first shape above: lay your index finger flat across the four strings from the D to the high E at the 2nd fret, your middle finger on the A string at the 3rd fret, your ring finger on the G string at the 3rd fret and your little finger on the B string at the 3rd fret. Don’t play the low E string.

An easier C9♭5
The full shape is a barre chord, hard at first. This one needs no full barre and sounds much the same: your index finger on the A string at the 3rd fret, your little finger on the D string at the 4th fret, your middle finger on the G string at the 3rd fret and your ring finger on the B string at the 3rd fret. Let the high E string ring open. Don’t play the low E string.
