Ritual trance has always been closely associated with music—but why, and how? Gilbert Rouget offers and extended analysis of music and trance, concluding that no universal law can explain the relations between music and trance; they vary greatly and depend on the system of meaning of their cultural context.

Rouget rigorously examines a worldwide corpus of data from ethnographic literature, but he also draws on the Bible, his own fieldwork in West Africa, and the writings of Plato, Ghazzali, and Rousseau. To organize this immense store of information, he develops a typology of trance based on symbolism and external manifestations. He outlines the fundamental distinctions between trance and ecstasy, shamanism and spirit possession, and communal and emotional trance. Music is analyzed in terms of performers, practices, instruments, and associations with dance. Each kind of trance draws strength from music in different ways at different points in a ritual, Rouget concludes. In possession trance, music induces the adept to identify himself with his deity and allows him to express this identification through dance.

Forcefully rejecting pseudo-science and reductionism, Rouget demystifies the so-called theory of the neurophysiological effects of drumming on trance. He concludes that music's physiological and emotional effects are inseparable from patterns of collective representations and behavior, and that music and trance are linked in as many ways as there are cultural structures.

In 2005, Tony Perman attended a ceremony alongside the living and the dead. His visit to a Zimbabwe farm brought him into contact with the madhlozi, outsider spirits that Ndau people rely upon for guidance, protection, and their collective prosperity.

Perman's encounters with the spirits, the mediums who bring them back, and the accompanying rituals form the heart of his ethnographic account of how the Ndau experience ceremonial musicking. As Perman witnessed other ceremonies, he discovered that music and dancing shape the emotional lives of Ndau individuals by inviting them to experience life's milestones or cope with its misfortunes as a group. Signs of the Spirit explores the historical, spiritual, and social roots of ceremonial action and details how that action influences the Ndau's collective approach to their future. The result is a vivid ethnomusicological journey that delves into the immediacy of musical experience and the forces that transform ceremonial performance into emotions and community.

A Well-Tempered Mind investigates the intriguing connection between music education and brain development in children. Peter Perret and Janet Fox use the details of an innovative music education program for elementary school students to explore this fascinating relationship. A Well-Tempered Mind describes how the students of Bolton Elementary in Winston-Salem, North Carolina, and a local quintet worked together and then explains the ongoing research that focuses on how music engages the brain’s cognitive capabilities, from memory and language to emotional processing. Music, A Well-Tempered Mind reveals, is a universal language that expands young minds in essential ways. 

“The authors put flesh on the feeling shared by all music teachers that the experience of music enhances thought and learning in unexpected directions, well beyond the simple act of enjoying the sound. … It’s exciting and necessary reading for all who are battling to ensure the place of music in the school curriculum."—Times Educational Supplement
