Abstract: To observe the influence of air and lip-pressure variations on reed motion, a blowing chamber containing an artificial-embouchure device was constructed into which a clarinet was inserted and sealed at the barrel joint. A DC light source was directed through the bell end of the clarinet into a photo transistor mounted near the mouthpiece. Light fluctuations produced by the reed's movement were converted to voltages and directed to an analog-to-digital converter unit interfaced with an Apple lie computer. In air-pressure experiments, lip pressure was held constant while air pressure was varied. In lip-pressure experiments, air pressure was held constant while lip pressure was varied. Intensities were measured on a sound-level meter and air-pressure was monitored via a U-tube water manometer connected to the chamber; thus, the reed's vibrational patterns were observed at specific air pressures, lip pressures, and itensities.
