I find this a fascinating subject, one that has interested me for many years!
Why is it that you simply stop listening to certain music (I limit myself to “classical” or “art” music here) while you never tire of listening to a handful of select composers?
To the last category, in my case, belong only Beethoven, Debussy and Ravel, I have loved their works from the beginning and the appreciation was always a constant factor.
I see that certain people have the same issue with Chopin and Mozart as I had.
I loved Chopin in my formative years as a teenager, but later, when studying music professionally in my early 20s, I even despised him at a certain point! Instead, I started to discover and focus on Liszt. It seems that there’s a sort of conflict between the two in terms of appreciation…only now, in my early 50s, I can enjoy and value them both at the same time.
For a long time I thought of Zart as a superficial, “pretty-pretty” lightweight composer, but that was before I discovered his operas and some of his symphonies and chamber music. On a whole, I never like to play him on da 88 but when I do, I try to imagine other instruments or a vocal approach.
The great Russian romantics (Tchai, Rach, Scrib) I mainly enjoyed in my 20s and 30s, but in the last 10 years or so I hardly listen to them anymore. Instead I developed a taste for Medtner and Prokofiev, mainly.
Then there are composers that only came in the form of a craze, like Mahler, Varese or a handful of other more modern composers. I used to be addicted to Mahler Symphonies, for about a year I didn’t listen to anything else…now I can’t really stand his music anymore, instead I focus more on antipode Sibelius.
Then there are composers that I’ve only learned to appreciate in recent years, like Grieg, Brahms and Fauré - they now belong to my favourites.
A separate case is Bach…as a youngster I hated his music - but gradually in my 20s I started to appreciate him but only by means of Busoni and other Romantic transcriptions. Gradually that changed too and now I prefer him in pure unadorned form - which means I also like to listen to HIP performers.
