Abstract
Multiple channel anechoic recordings of the musical instrument parts in Mozart’s Symphony in G-Minor (First Movement) are analyzed to study how the directivity patterns of each instrument varies with time. Static directivity patterns are well-documented for many musical instruments, but studies on how their directional patterns vary with time are not as common. Changing directional patterns in time, however, have been found to impact the realism of room acoustic computer modeling simulations. Previous work at the University of Nebraska has suggested a method for studying the time variance of musical instruments across a number of simultaneously recorded channels in an anechoic chamber. The method involves time-windowing each channel and analyzing how the overall directivity index changes across time and frequency. Comparisons of results from some of the fourteen instruments included in this Mozart symphony are presented. [Work supported by a UNL Undergraduate Creative Activities and Research Experience Grant.]
