Course
Description
[under construction]
General introduction to the science of sound and
its application to musical composition and performance. The course
emphasizes those areas of acoustics where scientific knowledge can enhance
musical performance and increase musical awareness. Most topics are
approached through relevant musical examples and discussions incorporate the
five basic components of musical acoustics: physics, music, physiology,
perception, and cognition. In the examination of musical instruments,
the acoustical features of instrument design are related to their function
in musical performance, incorporating live performances on a variety of
instruments.
Students are introduced to digital sound recording, processing, and analysis
and apply these skills to acoustical analysis of an instrument of their
choice. Depending on the students’ level of expertise, signal
analysis techniques can be combined with musical instrument modeling,
offering converging methods of investigation. Special emphasis is
placed on the acoustics of non-Western musical instruments. Traditional organology / instrument classification is compared and
contrasted to an alternative classification system based on acoustical
organology, introduced in the class. Additional topics include room
and architectural acoustics as well as analogue and digital sound recording
and reproduction.
