音乐生物学:我们喜欢听什么和为什么

Music as Biology: What We Like to Hear and Why

The course will explore the tone combinations that humans consider consonant or dissonant, the scales we use, and the emotions music elicits, all of which provide a rich set of data for exploring music and auditory aesthetics in a biological framework.

课程概况

The course will explore the tone combinations that humans consider consonant or dissonant, the scales we use, and the emotions music elicits, all of which provide a rich set of data for exploring music and auditory aesthetics in a biological framework. Analyses of speech and musical databases are consistent with the idea that the chromatic scale (the set of tones used by humans to create music), consonance and dissonance, worldwide preferences for a few dozen scales from the billions that are possible, and the emotions elicited by music in different cultures all stem from the relative similarity of musical tonalities and the characteristics of voiced (tonal) speech. Like the phenomenology of visual perception, these aspects of auditory perception appear to have arisen from the need to contend with sensory stimuli that are inherently unable to specify their physical sources, leading to the evolution of a common strategy to deal with this fundamental challenge.

课程大纲

周1 Course Introduction
Introduction to Music as Biology

Sound Signals, Sound Stimuli, and the Human Auditory System
An overview of the organization of the human auditory system, and how sound signals are transformed into sound stimuli.

周2 The Perception of Sound Stimuli
An introduction to the sound qualities we perceive, and how and why these qualities differ from the information in sound signals.

周3 Vocalization and Vocal Tones
A discussion of the nature of vocal sound signals, their biological importance and their role in understanding music.

周4 Defining Music and Exploring Why We Like It
The tonal phenomena that need to be explained in any theory of music, and different approaches that have been take to provide answers.

周5 Musical Scales
Why a small number of basic scales are used in music worldwide, and how a biological framework explains this and related puzzles.

周6 Music, Emotion, and Cultural Differences
How emotion is conveyed by vocal similarity in music across cultures, and how the speech of a culture and its music are related. A summing up
of the major points in the course follows.

Additional Resources
Additional demonstrations and commentaries by Ruby Froom on some of the musical issues considered in the course, as well as a glossary of
terms and bibliography for references.
