this is one of my favourite pieces of all time and now want to work on it.
but the problem is that if it would be too hard (especially the presto section) for me (just passed grade 8)???
Oh yes. Way, way, way, way, way, way, way, way, way, way, way, way, way, way, way too hard.
Ridiculously too hard.
Hard in a way you can not even begin to dream about.
At a similar stage in my development, I would merely have regarded such sentiments as those I express above as challenging me to do it anyway.
Assuming you do the same, then here are three tips:
- Pretend 'presto' means 'andante' for now.
- Learn it for now, then leave it when you give up the struggle to master it. Believe me, you will give up the struggle, but:
- Return to it once a year every year and relearn it. Eventually, you will get somewhere.
Have fun. I did. Still do, and the piece rewards me afresh every time I play it.
