The amount of time it may take for this "chaotic slide show" to settle down and produce consistent movements in my hands may be quite large, unless I consciously decide to make the slide show look the same every time, simplifying the physical problem of using sight to aid in execution.
I find you can look at left or right hands but rarely both. That you can look at the treble or bass clef but rarely both (though I've heard others claim otherwise).
Does anyone ever discuss whether or not it may be important when and how one's eyes move as you play a piece? Looking at your hands while playing definitely aids in correct execution....
I've played Chopin Etude Op25 No12. I play with music to familiarize myself with the layout. Like anyone else who's played it, you'll memorize the pattern and forget the structure. I write in the keys that this piece goes through and play from there. By the time you play it fluently, Op25/12 memorizes itself and you didn't even have to lift a finger.
for some reason I suddenly became very consciously aware of my eye movements at a certain fast(er) part, and the thought jumped to the front of my mind of "where am I normally looking right now?!?" The sudden awareness of my eye movements, and being completely at a loss as to what to do with them, actually distracted me so much that I started messing up relatively badly. D:playing for someone.
But as far as the eye movements being coordinated with the music exactly and done consistently every time, I'm not sure that's a good idea.
Yeah, I'd have to agree. The more different ways you can afford to operate without breaking down, the better. I think it's important to at least have some kind of a safety net. It's fine to normally operate in a certain way, but I don't think anyone ought to be overly dependent on a fixed scheme.
The question would have to be though- did the eye movements necessarily cause you to mess up? Or did your eyes start flashing around everywhere because of a level of uncertainty?
Yes. I often have my students purposefully look in different places while playing a section, and that seems to make it more secure. For example:"Play it while you look only at your RH""Play it while you look only at your LH""Play it with eyes closed""Play only the RH, but look at your LH"etc.
