FRET BOXES

Notice that these shapes are almost identical to standard open C, A, G, E and D shapes. And remember all the hard work you put into avoiding accidentally muting strings with the undersides of your fingers? Well, now you can relax a bit, as for chords like C5 and A5 you’ll deliberately let your fingers choke the high E string. For G5, the underside of your second finger should mute the fifth string en route to fretting the low E.
