Peter, an improviser from Austin, TX, has been taking detailed notes about his improv workshops (there’s an entry for each if it spans multiple days). for a total of 36 sets of notes. The workshops include teachers like Johnstone, Besser, Dassie, Three For All, and all 16 days of his iO summer intensive(!).
It’s a great resource and a good way to learn when you’re taking a workshop. I’m honestly surprised that I only rarely see Level 3/4/5 students taking notes. It’s good to be present but a scribbled note here and there can help cement an idea in the mind plus makes it easier to re-visit.
