Haven't been sleeping much, still. In lieu of more writing and paper sorting, I've also been listening to Bach, notably Glenn Gould's recordings of the Goldberg Variations. I mention this because I have only just remembered Johann Nikolaus Forkel's biography of Bach, specifically his claim that Bach composed the Variations at the request of the insomniac Count Hermann Karl von Keyserlingk. The Count had the young virtuoso Johann Goldberg in his employ and, according to Forkel, he kept Goldberg awake throughout the night playing the harpsichord. Finally, the Count asked Bach to compose a piece of music for Goldberg (who was himself a student of Bach), something to lull him to sleep or, at the very least, enliven his sleepless nights. Thus, the Goldberg Variations.
The story is almost certainly apocryphal, but it's interesting nonetheless (or perhaps because of). I myself cannot vouch for the soporific quality of the Variations since I have been listening to them for several days now and the earliest I have been to bed since then is one in the morning and then I can't sleep for more than four or five hours.
