I'm learning this amazing piece of music from Nikolai Kapustin ... although I already play it well (kind of, at least most of it), I'm still unsure about some parts... so I decided I should ask someone.
In the video, this part plays cca around 3:30 ...
The problematic thing is the 8vb ... the -1 octave shift. I don't know whether the shift applies for the left hand only or for both hands since the right hand is playing in the bass key too.
I can't see which keys Mr Kapustin plays and the sounds are too blended...
My guess is that the keys the 8vb applies to are played like a build up from bottom to the accord played in fortissimo...so it goes like:
- Left hand: A0 + A1
- Right hand: A1 (+ left hand crossing the right hand for C#2)
- Right hand: A2
- Left hand: C#2
- Left hand: F#3
- Fortissimo accord
But I have always thought that 8vb for one hand applies for that hand only. With that logic, it would be played like this.
- Left hand: A0 + A1
- Right hand: A2 (+ left hand almost crossing the right hand)
- Right hand: A3
- Left hand: C#2
- Left hand: F#3
- Fortissimo accord
Which is right? To me, the first one sounds more right (8vb applies to right hand too) but this particular composition already confused me so many times until I understood its tonal relations...
(I just realized I probably numbered the keys wrong, in the picture A0 = most bottom key on claviature)
