Liszt’s Eroica - How to play?

[danesi]

Hey guys, I’ve been learning a few of Liszt’s Transcendental Etudes, and I’m having quite a bit of trouble with one in particular, the Eroica. It’s not the runs I can’t do, nor the polyphonic texture. Rather, the only part I can’t play is the ‘con bravura’ octave runs. I tend to miss notes a lot even though I spend hours practicing those octaves. Can someone help me with my octave technique so that I can better my performance skills?
           Much appreciated,
                      Danesi

It's difficult to give specific advice without seeing you play. Wrong notes are usually due to inefficient technique/tension. Can you post a video?
