Description
Imitation is the genesis of change. One basic principle of human nature is that people imitate what they see and hear. In the professional choral arena, musicians extend the high art of imitation through fine-tuning, and creative reinterpretation. Stimulated by this cycle, the color of the twenty-first-century professional choir shifted compared to that of professional choirs from the 1950s through 1970s, causing an evolution in choral sound. In a series of interviews with iconic composers and conductors of professional choirs, the subjects involved in the study conveyed comprehensive and personal accounts outlining how professional choirs have refined the standard of choral sound. The paper is organized into three sections: (1) where have we been, (2) where are we now and (3) where are we going? It explores various conductors' perceptions of how and why choirs are unique when compared to earlier generations and what they believe caused the shift in choral tone. Paired with this perspective is the role of modern composers, whose progressive compositional techniques helped shape the modern choral sound. The subjects involved in the study further theorize how current inclinations may potentially shape the future of professional choral music. Although the subjects expressed differing opinions about the quality of the twenty-first-century choral tone, many agree that there have been specific transformations since the 1970s. The shift in choral tone occurred due to developments in vocal technique, exploration of contemporary compositional extended techniques, an adherence to historically informed performance practice, imitation of vocal colors from numerous cultures, incorporation of technology and emulation of sound perceived on recordings. Additionally, choral music subtly became prominent in film scores, and innovative conductors created progressive concert programming, and developed novel approaches to entertain audiences.

Description
Human perceptual dimensions of sound are not necessarily simple representations of the actual physical dimensions that make up sensory input. In particular, research on the perception of interactions between acoustic frequency and intensity has shown that people exhibit a bias to expect the perception of pitch and loudness to change together. Researchers have proposed that this perceptual bias occurs because sound sources tend to follow a natural regularity of a correlation between changes in intensity and frequency of sound. They postulate that the auditory system has adapted to expect this naturally occurring relationship to facilitate auditory scene analysis, the tracking and parsing sources of sound as listeners analyze their auditory environments. However, this correlation has only been tested with human speech and musical sounds. The current study explores if animal sounds also exhibit the same natural correlation between intensity and frequency and tests if people exhibit a perceptual bias to assume this correlation when listening to animal calls. Our principal hypotheses are that animal sounds will tend to exhibit a positive correlation between intensity and frequency and that, when hearing such sounds change in intensity, listeners will perceive them to also change in frequency and vice versa. Our tests with 21 animal calls and 8 control stimuli along with our experiment with participants responding to these stimuli supported these hypotheses. This research provides a further example of coupling of perceptual biases with natural regularities in the auditory domain, and provides a framework for understanding perceptual biases as functional adaptations that help perceivers more accurately anticipate and utilize reliable natural patterns to enhance scene analyses in real world environments.
