A Will-o'-the-Wisp (Medieval Latin: "foolish fire") is a ghostly light. It is seen by travellers at night, especially over swamps and marshes. Usually a Will o' the Wisp looks like a ball of light or a small flame
Some people think Will o' the Wisps are souls, spirits or spaceships. Scientists try to use natural explanations. Some say they are gas, like methane, that come up from the ground and burns. Other say they are electrical, like balls of lightning. There are many old and new stories about Will o' the Wisps around the world. Regarded as an exemplary recording, a musical fusion of jazz, classical and world music, Sketches of Spain is an album by Miles Davis, recorded between November 1959 and March 1960 in New York City. The album contained a piece called Will o' the Wisp, based on music from the Spanish composer, Manuel de Falla's ballet El Amor Brujo. El Amor Brujo (Love, the Magician), is sometimes translated as Wedded by Witchcraft. The whole work is distinctively Andalusian in character with songs in the Andalusian Spanish dialect of the Gypsies. The music contains moments of remarkable beauty and originality; as well as the Will-o'-the-Wisp, celebrated titles such as the Ritual Fire Dance, Song of Wildfire and Dance of Terror were also included in the original ballet score. Ian Ernest Gilmore Evans (1912–1988) was a Canadian-American jazz pianist, arranger, composer and bandleader. He is widely recognised as one of the greatest orchestrators in jazz, playing an important role in the development of cool jazz, modal jazz, free jazz and jazz fusion. He is best known for his acclaimed collaborations with Miles Davis, including Sketches of Spain, Porgy and Bess and Miles Ahead.
