Today, performing musicians face many challenges that require them to push the limits of what is possible both mentally and physically. They are expected to reach ever-higher levels of technical proficiency; what seemed virtuosic or even impossible a few decades before soon becomes standard. One must know an increasingly wide repertory and practice and perform in an expanding world in which travel can be a constant drain on time, energy, and concentration. Under these conditions the pursuit of perfection can become a hindrance for many artists who, in the process, lose the joy of performing and the ability to do their best under such difficult circumstances; they can also become more prone to injury. A growing body of evidence from physicians, physical therapists, and other medical experts, as well as the testimony of musicians, indicates that Yoga has been used successfully in the prevention and treatment of injury, and to remedy psychological problems such as performance anxiety and lack of concentration. This paper identifies specific injuries encountered by performing string musicians, and reports on successes in treatment of these injuries with Yoga as recorded in medical sources, reported by Yoga therapists, and documented by musicians themselves. In each case, this evidence is followed by my own suggestions for beneficial Yoga poses and practices drawn from personal experience and from interviews with Yoga teachers. Following the discussions of physical injuries, I include a chapter documenting the effectiveness of Yoga in treating psychological challenges such as performance anxiety. I close with a summary of my findings, offering Yoga as a valid and successful avenue for musicians dealing with these problems.
