Sleep

I dropped of listening to L'Estro Armonico by Vivaldi. That collection includes the b minor concerto for four violins, that Bach re-worked as his concerto for four harpsichords in a minor. I'd forgotten how good these are. I remember waking up a lot during the night deep in thought, but I can't remember what I was thinking about. I got up just after six, having been awake for a long time.
