Be prepared to exercise your eyeballs minus head movements when tackling large leaps, especially those hand-over-hand acrobatics that are intrinsic to many of Domenico Scarlatti’s sonatas.
In the first video I’ve isolated a few of these jumps from Sonata K. 113 in A Major, demonstrating what I’ve found to be the best approach.
While I’ve crashed and burned on more than one occasion, a new consciousness emerged through trial and error.
1) No bobbing head back and forth when playing crossed hands.
Use your shifty eyeballs, if necessary, to target the destination notes going back and forth over your right hand.
There are two places that stand out in this sonata. The first involves two octave, crossed-hand jumps. The Left travels back and forth over the right multiple times.
In the second instance, there are jumps of four octaves, and these can be suicide trips, unless mediated by shifty eyeballs.
2) Use an arc-like motion back and forth, but not too high, or you’ll lose contact with the keys.
3) Block out the broken chord progressions in the right hand as they move in sequence. Then unblock them before adding in the left hand.
Be calm, relaxed, and breathe deeply but not anxiously.
Finally, say a prayer..
