In A Misalliance, Blanche's dull ascetic suitor is represented by his predilection for the Brandenburg Concertos. Lewis Percy has more Romantic tastes: he listens to Mahler 6 at one point, and sobs at Manon.
Mrs May, in Visitors, longs for the noble sound of Schumann or Brahms, and I think it is Zoe in The Bay of Angels who also listens to Schumann. And in one of the early 90s novels, Brief Lives or A Closed Eye, characters attend a performance of Swan Lake.
Brookner's musical choices, then, are somewhat conventional, and her comments a little bland, in contrast to the sophistication of her references to the visual arts.
(A postscript - or perhaps a coda: Because of Anita Brookner I got interested in her almost namesake Anton Bruckner, and I fondly remember hearing Bruckner's Eighth under Dohnanyi at the Theatre du Chatelet one long-ago Parisian evening. It was a very Brooknerian experience, for me at least.)
