I sure feel almost the same thing about liking of music. I used to like serious and complicated music in my young days. However, I am inclined to love more of the simpler and lively music nowadays. A few days ago, when going to sleep, I accidentally chose the Nr 5 string quartet by Beethoven, OP18-5, which was composed in his late twenties. Honestly speaking, I have looked down or thought little of those works composed at the same time with the opus number starting with 18.
What a lively, vivid and beautiful music it was! Of course, not like the later string quartets, it was taken the form of the precedent great composers like Haydn. It still sounds vivid and full of joy of music, I should say, or of life. Except for the dramatic OP18-4, I have paid too little attention to the other 5 string quartets of OP18. Emergence of such early string quartets of Beethoven as an absolute attractor to me may be because of the same psychological dynamics, that is, the attraction of young, lively and energetic things being lost by such an old man as me. Just listen to this lyrical and lively music. OP18-3 D major.
