big Medtner fan here. honestly one of my top and absolute favorites , I've read up a lot on and about him ,not sure I understand and certainly don't agree w calling him a Russian Brahms.....so many things wrong w that description. but I always seek to understand, please where ever did you hear or read this about him? I'd love to pull the source or book etc and read it
Brahms music isn't exactly well written for piano, very orchestral type writing, and awkward as heck at times
but w Medtner there isn't a single piece of music or excerpt of something od this that feel strange or odd to play at the piano, it feels like he put down was done either when at the piano, or after he'd worked it out at the piano, or done away from the piano but with the instrument particularly in mind at least ,also we can pretty much follow an evolution of ideas and development from Beethoven to Schumann then to Brahms
I have trouble finding and drawing a strong lineage in composition and musical style for Medtner
maybe Tchikovsky to Arrensky and Taneyev and then to Rachmaninoff in terms of a Russian analogue to Brahms and German side , albeit much more piano friendly and still harkening back to Bach
thanks for any info you can provide on origin of that statement as I haven't ever come across it
