I'm working on Lavapiés from Iberia's 3rd book and have been struggling to find a convincing way of rendering the chord highlighted in red. I have rather large hands (I can smack the Ab7 two bars before, although it doesn't sound very good) but the combination of the even spread and the jump preceding it makes it practically impossible to roll this chord without: a. hitting middle C with the index finger, b. thumbing the Gb below the top Ab, c. missing the lower Db, or d. dropping the higher Db entirely. It's not so hard in the earlier section when there's time to prepare it.
I understand this is a piece for which the best way to practice is to stop and learn something else, but I don't want to give up so soon. Does anyone have any tips for positioning the wrist/fingers to smoothly roll this which doesn't require so much preparation time? Is there any good alternative to break it up which doesn't involve dropping notes?
Looking at Díaz-Jerez' performance it seems like he uses a straight-finger approach, but there's a pause associated with it.
I have everything up to this bar and the next few phrases after it passable without undue suffering.
