The third and final concert of the season with the Diotima Quartet brings this year’s residency to a close with Beethoven’s Opus 132, one of the composer’s most majestic and moving works. Everything about this work is imposing: its five-movement structure, the no fewer than 264 bars of the introductory section, its arch-like structure, and the palpable sense, in every movement, of the composer’s illness. Beethoven at the height of his artistry as a chamber musician.
