First prize winner of national and international composition competitions, Christopher Muscat's works have been performed all over Europe as well as in Africa, China and the United States in such prestigious venues as the Berliner Philharmoniker, the Shanghai Oriental Arts Centre and the Grand Hall of the Tchaikovsky Conservatoire in Moscow.

Muscat's wide-ranging interests as a conductor vary from sacred to contemporary music and he has conducted and recorded numerous world premieres by contemporary composers. Through his pioneering work, he is largely credited with having revived interest in Gregorian Chant in Malta (both in liturgical and concert settings) as well as in one of Malta's finest romantic composers, Paolino Vassallo.

Muscat is the Music Director of the Jubilate Deo Choir, Maestro di Cappella of the Metropolitan Cathedral and Music Director of Fondazzjoni Paulus. For many years he has taught sacred music at the Archbishop's Seminary and at the University of Malta.

Muscat occupied the posts of Artistic Director and Chairman of the Malta International Choir Festival between 2011 and 2017. He is a member of the World Choir Council and is regularly invited to judge international vocal, instrumental and composition competitions.
