Everything up until now seems to be rather malinformed guesswork. But I might be wrong.
Well, I have studied the score extensively, and have even entered movements of it into my computer to hear what it sounds like. So I have a pretty good idea as to what it's like.
dnosaurtales, some time, I might make a thread dedicated to my computer's recordings of the OC. Then you can hear what it's like.
In the meantime, you should check out Sorabji's other music, all of which is available on Amazon.com. Here is what I recommend:
In the Hothouse -
You don't even need to buy a CD to listen to this. Go here -
https://www.sorabji.com/sound/piano/hothouse.ram. This is typical of Sorabji's slower, dreamier music.
Fantasie Espagnole -
I suggest you listen to this before anything else by Sorabji. It is almost like Debussy/Ravel, yet it also gives one a faint idea of what Sorabji's general style is. The themes are catchy, something that isn't really true of his later works.
Le Jardin Parfume -
This is arguably one of the beautiful pieces I've ever heard. Every time I listen to it, I feel like I'm in another world. I can't even describe the beauty of this piece, so I'll leave it to you. I doubt you'll be disappointed. Also it's based on the erotic text
The Perfumed Garden, which is, by itself, an interesting read.
Gulistan -
Another nocturne. Beauty melodies throughout.
Sonata #1 -
A beautiful piece, but it takes a bit of getting used to. It's a lot like late Scriabin.
After you've listened to these, then you can move on to:
Toccata #1 -
Very beautiful, not a typical toccata. It has the same atmosphere as certain movements of the OC.
Sonata #4 -
Over two hours long, but incredibly beautiful. I suggest you listen to this last, however, because you might not like it if you aren't aquainted with Sorabji's style.
