NRSC4450 - Music and the brain: the new and old science of music

In a world where humans can't seem to agree on much of anything, there is one thing that still unites us: we love music. Why should abstract sequences of sounds give us such strong emotional reactions? Why indeed should they give us any emotional reaction at all? On every continent, today and throughout history, there is not a single human culture that has ever been described that does not make music. Within cultures, music is so ubiquitous that we actually have clinical terms (amusia and musical anhedonia) to describe people who don't understand or don't enjoy music. And yet, despite this ubiquity, the evolutionary origin and purpose of music remains unknown. Not only do people everywhere make music - they do so in fundamentally similar ways. All over the world people divide rhythm into twos and threes; all over the world people divide the frequency spectrum logarithmically, in octaves; with a very few exceptions, we divide octaves into no more than 12 steps, and we use subsets of 5-7 of these tones at a time. Not only that, but many cultures seem to have independently arrived at the same sets of 5-7 notes. These are probably not coincidences. If not coincidence, then what? In this course we look for explanations to these and other questions about music by looking at something that humans all over the globe have in common: the brain. Using readings from the primary literature and classic texts, supplemented with software exercises and analysis, we will see how many of the age-old mysteries and questions of music can be either answered or in some cases amplified by a consideration of brain mechanisms. Thinking about music in the context of brain function also provides a biological and evolutionary rationale not just for why music is the way it is, but why it should exist at all. More broadly, this course is an example of what can (and cannot) be accomplished by addressing aesthetic and philosophical questions as scientific and empirical ones. Prerequisite: NRSC 1110 and prior musical instruction, any instrument.
