Stéphane Moucha was born in 1968 in Most (Czech Republic). Shortly after his birth, his parents fled the country and found asylum in France, where he started his musical education at the age of 5, learning to play the violin. After completing his instrumental training, he entered the Paris Conservatoire National Supérieur de Musique, where he studied composition, harmony, counterpoint, fugue and orchestration. As a former assistant of the composer Gabriel Yared and as an orchestrator, he has worked on numerous American movies - including "The Next Best Thing" (directed by John Schlesinger), "Autumn in New York" (directed by Joan Chen) and "Possession" (directed by Neil Labute).

Independently he has composed for a variety of French television and feature films. He has also arranged songs for Charles Aznavour and Jane Birkin for recordings and stage performance.
