Modifications of the Mind incorporates improvisation into a fixed compositional structure. The 6 parts (after the post-produced intro) are performed in real-time based on loosely organized instructions and durations. It is performed on electric valve trombone, a valve trombone outfitted with buttons and sensors to provide control over a computer program developed with MAX/MSP which alters the trombone,s sound in unique and surprising ways.
Modifications of the Mind represents the Yoga Ashtanga outlined by the ancient sage Patanjali. These practices from the Yoga Sutras have become the basis for many branches of modern Yogic philosophy and can be seen as a guidebook for living a peaceful and contented life.
