Colette Mourey is a guitarist, professor of music, a researcher in musicology and a French composer, born in 1954. She studied musicology at the Sorbonne under the direction of Edith Weber and passed the aggregation. First a classical guitarist, the student of the Uruguayan guitarist Oscar Caceres. She is also a pianist. As a teacher, she teaches the writing, aesthetics and didactics of music at the University of Franche-Comté and at the Higher School of Teaching and Education. For her researches, she started work on the atonal music of her teacher Julien Falk, to develop a new musical system called "hypertonality". It is based on spiral scales (in amplitudes greater than the octave), radically transforming the techniques of atonal counterpoint. This allows the reintroduction of "natural sounding" in a contemporary language, which helps to bring contemporary music to the "general public". She is the author of numerous books on musicology and education. She has won several First International Prizes (“Music and Earth”, 2012), three Grand Prizes, from the IBLA Foundation (2012, 2013 and 2014) and Fondazione Adkins Chiti: Donne in Musica Selections for “Abacus”, “Quintetto La Maestria” and “3 Variations sur l’Hymne Européen”.
