Dr. Don Greene introduces the Performance Skills Inventory (PSI), an 84-question assessment that identifies the critical factors that keeps musicians from preforming up to their potential under pressure . Is it performance anxiety? Confidence issues? Tentative playing? Inability to focus? Difficulty recovering from mistakes? Dr. Greene developed the PSI over the course of 15 years, based on his expertise in sport psychology and his work with performing artists at The Juilliard School, New World Symphony, and with professional musicians. The PSI generates a profile of one's performance strengths and weaknesses. It is accompanied by a workbook: 11 Strategies for Audition & Performance Success.
