There is a somewhat difficult chord near the beginning of Isaac Albinez's Austurias. I will post it in tablature form for the sake of convenience:
I can barely form this chord in 30 seconds, let alone in line with the song at the tempo it was meant to be played at.
My guitar has very little action, I'm holding strings very close to the frets with the tips of my fingers, my nails have been trimmed to the flesh, I'm using the side of my index for the barre, my thumb is held relaxed but firm at the middle of the neck (not over like Carlos Santana) and yet after a considerable amount of practice I still can't form this chord without strain or muted string.
I really can't foresee my current form improving much with additional practice so I guess I am doing something wrong.
Are there any tricks to playing this?
