At bar / measure #5 of Bach' Premier Prelude (Prelude and Fugue in C major, BWV 846), there is that awful chord which starts with:-
C on the fifth string, third fret
E on the fourth string, at the second fret
A on the third at the second fret
E on the second string at the fifth fret
A on the first string at the fifth fret
I've noticed some players play it by barring the second and first strings at the fifth with the pinkie, others use the third finger on the second string, fourth finger on the first string.
You can, of course, finger it elsewhere, but that doesn't really help much. At the seventh fret it's easy, but it doesn't sound right to me.
I'm sure that there must be many guitarists here who have mastered it. I would love to hear how you did so, and also any tips, techniques for developing the hand for the stretch, or just ways to make it easier.
