Yes, a very interesting composer. I hope to cover his music in a future video.

There's definitely a thread connecting those two.

@@NickBacchetto scriabin is their mediator

I procured mine from Durand many years ago. It may be worth writing to them.

Thanks! My score is published by Éditions Henry Lemoine as "Nicolas Obouhow: Oevres pour piano".

Yes, he was ahead of his time. As far as pieces inspired by stars, there's Takemitsu's Orion, Crumb's Makrokosmos, Xenakis' Pleiades, Cage's Atlas Eclipticalis and Stockhausen's Sirius, off the top of my head. Some of the pieces map constellations onto some musical parameters (pitch, time, dynamics) and others are more generally evocative of the vastness of space. Good luck!

@@NickBacchetto Thank you for your recommendations, I took a while to reply because I wanted to check them properly and I was a bit busy. Takemitsu's piece sounds really interesting and I like the overall mood it portrays, although I have no idea how I could map that into the possibilities a piano can offer (yes, I should have said for what instrument I was going to compose the piece). Crumb's piece has a lot of interesting techniques but the style I want to use will be way different, although I can still use some ideas from that piece (also I understood Crumb was mainly portraying the name and cultural context of the constellations instead of the stars themselves and I want to do the opposite). Xenakis piece was interesting too but I'm not sure I understood it, anyways bell-like sounds seem to be common in music related to the cosmos (the piano harmonics in Crumb's piece for example). Cage's piece reminded me of NASA's sonification of Hubbel's Deep Space image, and I will be using a similar idea too to depict the Orion constellation. Stockhausen's piece offered me a bunch of ideas, usually I get more inspiration from him than from any other late 20th century composer; I think the pulsation gestures will come handy to represent the pulsar Betelgeuse will leave behind or the luminosity fluctuations of the stars. Also right now I noticed you followed me, thank you for the support and interest!
