Listening to a top tier orchestra (like the best- The Chicago Symphony) is like listening to the sounds of heaven. Just incredible.
Much of the problem today is the forced feeding of new music to an audience which basically hates it. Hence, Beethoven is paired with John Cage or Schoenberg.
I was blessed as a child to have attended the Saturday Morning Concerts at Boston Symphony Hall which were aimed towards children and sometimes had amazing guest conductors who explained the music before playing it.
Leonard Bernstein was a frequent guest, and it was under his baton that I first heard the Hallelujah Chorus from Handel’s Messiah.
It was over a half century ago, and I still remember exactly how it sounded and felt.
Leonard used to throw in some atonal stuff, but it was usually his own, like the overture to “Candide” which still had discernible Melodies, Harmonies, and Rhythm, which are, IMHO, necessary in music.
