(Interesting that there's also a question on trills in Op. 101. These come up in this sonata too, and I've found the tips really helpful).
I'm learning Beethoven's sonata for piano and cello Op. 102 no. 1 in C major for a masterclass (at the moment alone without the cellist). I know that my technique is lacking for this sonata, but I received it as an assignment, and I'm struggling with some places and need urgent help or tips on how to practice or approach them, if possible.
1. Octaves in fast dotted rhythm in the left hand (bar 2,
tempo about 144-160 to a quarter note, originally "allegro vivace" with no metronome indication by Beethoven). I haven't played lots of music with octaves and have a big technical hole there, especially with the left hand, and I'm not always sure when they should be played from the wrist, the arm, or otherwise (here, for example).
Most of the tension accumulates in my middle fingers, which I know is not good. I try to bend them inward to counter the tendency to stretch and tense, but this also hinders movement.
2. Tremelo broken chords (left hand)
: Should one aim for a movement that "brushes" the keys or slides on them? I practice the 16ths in different rhythms, but they are so uncomfortable and completely fall apart when I add the right hand I can't see how I can get this passage even close to tempo in two weeks:(
This recording is on the slightly slower side, but I chose it because it has the score (couldn't manage to insert pictures).
Any help would be much appreciated!
