Abstract
During the past 3 years, the author has participated in a program to review and redesign the entire bowed string line of a major manufacturer, using new materials and manufacturing techniques in addition to traditional designs and methods. Computer programs have been created, both for design and for control of quality. In testing hundreds of strings, some anomalies have been seen, including persistent whirl modes and variation of frequency and damping with amplitude. Attempts have been made to ascertain whether such conditions may affect musical performance. The action of rosin has been studied, and temperature at the bow-string interface measured with a calibrated infrared video camera. The greatest difficulty has been correlating opinions of musicians with actual measurements, a problem that is not unexpected in musical acoustics.
