I've been sent details of a workshop called 'Unintentional Music: Releasing Creativity and Transforming Stage Fright'. It comes out of Process Work, which was developed by Arnold Mindell, who trained as a Jungian but was dissatisfied with psychotherapy's lack of interest in the physical body. Though I'm not a fan of the packaging of his most recent books, his earlier ones are interesting, exploring the link between physical symptoms and dreams.
Here is some of the blurb (contact me by email if you want the full details):
Whenever we create, just like in other areas of our lives, some things happen that do not go along with our intentions. The unintentional aspects of the music we make - the unwanted note, the cracked voice, the strange croaking sound we try to avoid, the rhythmic problem we cannot erase even after hours of practice - contain more wisdom than we think.
They are intimations of parts of ourselves, and of our music, that lie beyond our awareness. Exploring the unintentional with curiosity and love can help us tap into the wellsprings of our deepest creativity and make our music, and ultimately our lives, more authentic, meaningful, and original.
The guy running this workshop is not Arnold Mindell, but an experienced Process Worker who seems to specialise in creativity and performance. You can see his book here. I'm going.
