The first step: Whenever you attempt a jump, glance at the note you want to hit, keep it in your mind for a split second, look away, and make the jump.
Agreed. I played Liszt Spanish Rhapsody (not super well ) for auditions, and the climax section in D major where it alternates between blind jumps and interlocking octaves gave me lots of trouble.
FWIW, not to try to steal thunder from ranjit's extremely good set of observations, but that was my first thing on piano, just junkyard ragtime and whatever: yes, I did learn the scales properly at a bit later age, but making wide leaps is, for a number of kinds of music, even more natural than running scales.
Say I need to jump with the LH from a low Ab to a C natural two octave and a third higher. I start at the low Ab and then jump to then Ab an octave up, then back down, then up to the Bb a ninth up, then back down, bouncing up and down until I've reached the target C natural and even gone a bit above it.
Just a thought -- Isn't this pretty much exactly what la campanella does for the RH?
Initially, start out with some soft LH arpeggios, then build up to that left hand pattern, and bam, you've got yourself an arrangement people will dig! Nowadays, whenever I see a few left hand jumps, I breathe a sigh of relief! I'm always tempted to do the ones in the Chopin waltzes in octaves, and an octave below where they were intended, just for the heck of it.
Maybe so. As soon as I climb Everest, swim the English Channel, and run the length of the trans-Siberian railway, I'll have a look at tackling La Campanella.
