This is a purely personal note.
After listening to a Brahms Symphony, I understood what was missing from my current way of living - good music. It has been almost a year since I last listened properly to a performance of classical music. Listening to Giulini conducting a Brahms was like swimming in a cool spring on a nice bright summer afternoon.
This phenomenon suggested to me that music is not just an accessory to life. It constitute the movements which my mind makes at a level deeper than explicit self-consciousness.
I have been exposed to much junk "music" and noise. And for a quite considerable length of time. I will now buy a new set of stereo speakers and start listening seriously again to classical music.
