Exploring the paranormal through musical phenomena, this encyclopedia covers a range of anomalies, from musical mediumship to locations throughout the world where music has been heard with no obvious source. Other manifestations, such as the abilities of musical savants and the anesthetic use of music during surgical procedures, are included with a focus on paraphysical aspects. Entries describe examples from earliest history up to the present--interpretation is left to the reader. Broader themes and concepts are discussed in appendices, with additional references provided for further study.
