I am listening to a piano music and it raised a question which I was thinking about it for a long time:
Why do pianists start with nice melodies and they ruin it afterwards?
They suddenly change the style. The audience who loved the previous style might find the new style harsh or jerk.
This description is subjective so to avoid offending professionals, I call the styles A (pleasant) and B (I cannot feel its beauty). These grouping is distinctive for we amateurs.
In this example, the music begins pleasantly from 0 to 48th second (A). Then it becomes (B). Then from 1:27 to 1:41 it becomes (A) then (B), from 2:40 to 2:56 (A) again. Then (B). Then (A) from 3:40 to 3:53. From 3:58 harsh to the end.
I know many of descriptions are subjective and I hope no one gets offended.
Why don't pianists keep the melodies playing in their best way?
