It was good to see this thread. Since I started playing chess more here at chess.com I have wasted a lot of time, true, but inspiration has flowed more freely, and I hope some opponents will forgive my occasional slowness as I might occasionally pause to adjust some music if I have a Sibelius file open in a window.
A few years ago, in my Aria How I Love My Smartphone, I included a reference to chess.com in the lyrics. At rehearsal, a fellow composer who also had a work in the same concert, got chatting about my piece and to my delight it turned out he also played chess on this website. Of course we got a match going, unfortunately he timed out after a few weeks and we have lost touch.
There are very clear analogies between chess and music for a composer, in particular in chord progressions - you have to keep a very careful eye on horizontal, lateral and diagonal motion, according to mathematical rules, and avoid redundancy.
It was good especially to read about Schoenberg's version of chess (one of my heroes).
No mention yet of chess problem composition, so aptly named and closest of all, perhaps, to music composition.
I will likely, in due course, write something more closely connected to chess.
Also the match between Prokofiev and Ravel, and the Duchamp/Cocteauc film, both on my profile, may be of interest to some here.
Thanks for the icecream ChessPlayin Dude...
