I hit you with baroque. It is intended to thrill. It belongs to a specific period. It refers to the ornate and heavily ornamented music of the said period ( from approximately 1600 to 1750). Perhaps the most easily identified is the compositions of Pachelbel, Handel, Vivaldi and Henry Purcell.
Abstracted Context: It's like you watch Madonna on stage and then have to listen to her recorded audio without the drama on stage.
Your criticism is not new. In fact that is what dogged the composers of baroque for a long time. The term itself was negative for some time.
Ravel and Debussy were masters of Impressionist music. Let me give you one of the best known compositions of Maurice Ravel:
Bolero. As you can notice, there are few if any sound aids. There is therefore need to multiply the instruments so the person sitting at the very end on the cheaper tickets can hear it. The idea of the composer is to to fill up the chamber with music - even at crescendo. Ravel, like Wagner believed in multiple instruments and truly delivered a concert with all those instruments playing in turns and ending together in one big effort!
First, let me say that I do not have problems with "classical music" in general---just with that type of noisy big-band racket. If, for some strange reason, I were minded to listen to "classical music", I'd probably consider musical things---on solo piano, piano+violin, piano+violin+cello, or at worst, one of those four-fiddler things---by the likes of Ravel, Satie, Debussy, etc.
I don't know what you mean by "abstracted from its context"; so that doesn't help me at all in understanding that mish-mash you hit us with. I can also think of numerous horrible pieces that are not meant to be "part" of anything (visual or otherwise); so that argument too doesn't help me.
