Then, out of a calmness that seemed to have all in the auditorium holding their breaths, the sweet, hymnlike opening of the final movement, carried by the string instruments, filled the hall. I was stunned: I had never before noticed how similar the melody in this movement was to “Abide with Me.” And that revelation steeped me in the deep sorrow of Mahler’s long but radiant elegy, and I felt I could also detect the intense concentration, the hundreds of private thoughts, of the people in the auditorium with me.
