In fact, one of the pieces I played I had "figured out" just that morning: A Brahms Intermezzo (Op. 118, No. 2 ), a work that had puzzled me for years.
After I played it one of the listeners said it was like listening to Brahms talking to himself and, in the most Brahmsian manner, not even knowing what he was saying. This is the sort of reaction I most treasure.
