Rachfan,
I worked at memorization the last one-two hours before hitting the rec button. Not so easy to memorize, but not extremely difficult either.
I'm very happy you find them communicative, as that's one of the things I really try to do.
Birba, very flattering, thanks! I'm starting to 'discover' Schnittke's piano music, not least by these studies of my own, and I begin to think there's greatness in the writing, which of course helps the performer a lot.
Nikolas,
First, this is how I recorded:
Separate video camera; separate condenser microphones going into a DAT machine. Sound and image was put together in windows movie maker. It's exactly as it was performed, the location is a church wich accounts for the reverberation. One Bösendorfer (2) and one Steinway (3&5). No editing, no sound effects. If it's bad it's not the recording, it's me!:)
In the Grave, the range is typically mp-mf-f-ff. ff's are usually followed by mf or mp. So, I try to achieve that rather than going to more extremes.
For example, at 00:33 a bar starts with a chord deep in the bass, marked f and cresc, ends with a comma-sign. Next bar starts at 00:37, marked mf. Out of respect for the score, and sensing that there' a structure here, I deliberately aimed for a more mf-ish sound there, rather than p or pp. The same approach in all the pieces, at all points. I must make sense of it, of course, and that's where you might not agree.
Cheers!
