PHYS 1204 - Physics of Musical Sound

(crosslisted) MUSIC 1466
(PBS-AS, PHS-AS)

Spring. 3 credits. Student option grading.

Assumes no scientific background but uses high school algebra. Open to all students and suitable for non-scientists; does not serve as prerequisite for further science courses.

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. At the level of The Science of Sound by Rossing, Moore, and Wheeler.
