Not a teenager. Mahler was 27 in 1888.

I thought he was 17; should have studied more math and less music in school.

Mahler (1860-1911) was 28. (My error).

The last 3 minutes is where, after a series of clever false starts in different keys, he ends up triumphantly in D Major, the tonic key, for a ride into pure affirmation. Mahler in the score states that the brass section should stand at this point. (Until recently, there was a You Tube video of Dudamel conducting the L.A. Phil with this.)

Thirty years ago I played this for a lady I was dating. She broke into tears at the end.

I found it!
