Whether referred to as mermaid, usalka, mami wata, or by some other name, and whether considered an imaginary being or merely a person with extraordinary abilities, the siren is the remarkable creature that has inspired music and its representations from ancient Greece to present-day Africa and Latin America. This book, co-edited by a historical musicologist and an ethnomusicologist, brings together leading scholars and some talented newcomers in classics, music, media studies, literature, and cultural studies to consider the siren and her multifaceted relationships to music across human time and geography.
