Overview
The Gnossiennes are several piano compositions by the French composer Erik Satie in the late 19th century. The works are for the most part in free time (lacking time signatures or bar divisions) and highly experimental with form, rhythm and chordal structure. The form as well as the term was invented by Satie.
Etymology
The etymology of the word gnossienne is contentious, but the word existed in French literature before Satie's usage, and is in the 1865 Larousse Dictionary, referring to the ritual labyrinth dance created by Theseus to celebrate his victory over the Minotaur, first described in the "Hymn to Delos" by Callimachus.
Another explanation is that the word appears to derive from gnosis. Satie was involved in gnostic sects and movements at the time that he began to compose the Gnossiennes.
