Few things are as fascinating as listening without a score to a classical masterwork and imagining the notation, especially the note values. This morning it was a question of a single measure out of hundreds in a "simple" 2/4 piece by Mozart. The rhythms of this measure were so atypical, yet so utterly innocent (on the surface of things) that they defied proper execution and they left me sure that I understood the error, though I did not. In other words, I could not second guess the master at his most diabolical.

No wonder musicians do not tire of his work.
