Hi wolfi,
I listened to your rendition of this prelude twice and believe you turned in a very creditable performance. It's well played--bravo! Also the Schimmel sounded very good and the minidisk method you used recorded the sound with great fidelity. If you were to spend a bit more time on the piece, you would probably polish just a few details, like evening out the ritardandos that reverse themselves into accelerandos to get the pacing of those more calibrated. In the sixth to the last measure, the ritenuto there is only for three beats, as you play it, but I'd still try to make more of it, even if it meant extending it a bit, in order to make the entrance of that rich left hand arpeggio on the down beat of the following measure more dramatic and colorful. I really like how you've layered the sonorities between foreground and background at all times, and featured the plaintive melody, despite the thick competing accompaniments. Overall, I believe you've captured the essence and spirit of the prelude with artistry. Congratulations!
Like I've said before, with the amount of concentration you put into composing, it amazes me how you can find time to also fit in standard repertoire, particularly learning new, complex pieces like this prelude. A man for all seasons!
Although I play many of the Rachmaninoff preludes, I've not done No. 12. The one I do have my sights on next in Op. 32 is No. 13 in D flat. The piece starts off... well, on the stodgy side, but toward the last section, it evolves into incredible chromaticism of ravishing beauty. The thing that really surprises me is that few pianists bother to explore or play it! I sometimes would swear that the young pianists these days truly believe that Rachmaninoff wrote only three preludes: Op. 3, No. 2 in C#m, Op. 23, No. 5 in Gm, and Op. 32, No. 12 in G#m. I'm sure you'd agree that so much music of great merit in these volumes is sadly overlooked.
