1st mvt is awesome
I once took my parents to hear the Fifth (Matthias Bamert and the Cleveland Orchestra). Thinking my mother would like the mellow Adagietto best, I asked her, after the symphony had ended, "Wasn't the slow movement beautiful?" She turned to me and said, "I liked the funeral march better." I was totally shocked! Way to go, Mom!
That said, I have to admit the Scherzo is my favorite part. That is the very heart of the symphony (the Adagietto is a mere interlude really, especially when played the way Mahler probably intended...polished off in eight minutes). But my very favorite
bit of the Fifth is the appearance of the great chorale theme near the end of the second movement and its triumphant return near the end of the Finale. Done properly, it definitely provides an emotional tingle.
