I can do it! I've lectured on Haydn's 'Lark' Quartet, taken a seminar, and ditto for Mozart's 'Dissonance'. I work on the principle that if you do something challenging often enough, it becomes commonplace.
In about five weeks' time, I'm giving a lecture on late 19th/early 20th century Scottish music. But I'm allowing myself a few nights off before I start preparing for it. I have plenty of non-academic books crying out to be read, so I might as well indulge myself.
