摘要

Cellists are interested in ways to produce the largest sound possible in order to meet modern acoustic challenges. This research examined cellists' lower body posture, how lower posture affected the manner in which the cello was held, and ultimately, what effect this had on the instrument's sound. Lower posture is significant because it affects sound production.;This research analyzed cello treatises, images of prominent cellists, and conducted sound lab tests. The treatise and image research investigated how foot placement, endpin length, angle, and tilt of the cello affected the amount of leg contact with the instrument. The sound lab research used a bowing apparatus and audio software to measure the effect of leg contact on sound production.;The results of this study showed that lower posture affected the amount of contact made between the player and cello. The sound lab tests revealed that less leg contact led to larger amplitudes produced by the cello. This research also discovered that the contact from each leg uniquely affected certain frequencies. Research on lower posture's effect on sound may benefit performing cellists, pedagogues, luthiers, and researchers.
