Just some idle thoughts on the practice of music appreciation based on personal experience. I’ve searched briefly, and there is a lot of scholarly work on this subject, but I have not read it. Perhaps in the future I will read about it and learn that I was wrong.
Fast and slow hedonic curves
In music, there is the concept of the hedonic curve. At first, when you listen to a piece of music, you may not get it. But as you hear more of it, your appreciation may grow and grow. But eventually, the novelty may wear off, and you want to move on to something else.
My anecdotal theory is that different people experience the hedonic curve on different timescales. Some people may go through the hedonic curve very quickly, while others go through it very slowly. If you go through the hedonic curve very quickly, you may frequently seek new things, and eventually learn to love an eclectic list of genres. If you go through the hedonic curve very slowly, you may be the kind of person who mostly sticks to one genre, and finds a handful of things to listen on repeat.
