It can also be quite a waste of time, if you take the written fingerings as given, take your time to learn it and then when you try to speed up the piece you cannot or the fingerings just don't work when the piece is put together.
So what is a good strategy? Of course I try to make the fingering as easy an comfortable as possible. And with easy parts there may be several easy ways to do it so I pretty much pick the first that comes to mind.
But in the difficult parts you will have difficult fingering. I see two main reasons for it being difficult:1. The sequence of movements or muscles involved are unusual and requires your brain to adapt to it - So you practice! 2. The movements are akward, physically impossible at high speed. Now #1 would obviously be regarded as the correct fingering and #2 the wrong. So how do you tell the difference before starting practice?
Maybe you will develop a "repertoire" of general movements that you know works for you?
Unfortunatly (for me) he focuses on making the fingering possible for people with small hands and I have rather long fingers so I find the "small hands" tricks rather distracting. E.g. in an arpeggio I always prefer to use as many fingers as possible before moving/crossing over.
I seen "Henle Verlag" mentioned a lot for their good fingerings, do you have experience with those? Are the fingerings completely written out? I guess it would hurt to get some ideas.
You should just try it at correct tempo already in the beginning (even if you mostly do slow practice). Also when working on small segments, you should every now and then try to play the whole thing through to see if it works.
Now I will only change if its painful or awkward at tempo. it's not such a big a deal.
Well you must of got somewhere, being able to figure out which ones didn't fit? You should probably post the specific sections you have issues for someone to help.
negatory, mine are small, for my size too (I cant play the rach 2 opening bars, either hand, but that doesn't say a lot hah - can only reach about a 9th if not playing keys between comfortably). In saying that my teachers are smaller than mine, but somehow - better stretch & flexibility.
You're a guy right? Try struggling to play an octave
