Physics of Musical Sound

Catalog description

This course explores the physics of musical sound. How and what do our ears hear? How does that determine the kinds of sounds we find pleasant and not so pleasant? How is sound generated by strings, pipes, and plates, and what determines the characteristics - pitch, timbre, attack, consonance, or dissonance - of that sound? How do the major families of musical instruments (string, wind, reed, brass, percussion) and specific examples (violin, guitar, piano, flute, oboe, trumpet, chimes, pipe organ) work, and how does that affect how they are played and the sounds they produce? How do we generate sound when we sing, and how does that vary in different kinds of singing? What makes for a good concert hall or listening space? These are explained using physical and mathematical concepts including vibrations, standing waves, harmonic series, beats, spectra, and logarithms, and illustrated using demonstrations, audio clips, and musical selections from a wide variety of genres. This course is a Writing In The Majors course: both science writing and physics problem-solving skills are developed through weekly assignments. Student activities include hands-on investigations of musical instruments and field trips. Students can expect to gain facility with physical and mathematical ideas having broad applicability; with music theory and psychoacoustics; and with their combined application to musical sound and how it is generated. At the level of The Science of Sound by Rossing, Moore, and Wheeler. (MUSIC-MT)
