List of compositions by Guillaume de Machaut

The French composer Guillaume de Machaut was the most prolific composer of his time, with surviving works encompassing many forms, the three formes fixes rondeaux, virelais, ballades, as well as motets, lais and a single representative of the complainte, chanson royale, double hocket and mass genres. Most of his extant output is secular music, a notable exception being the renowned Messe de Nostre Dame. His oeuvre as a whole represents an unprecedented volume of surviving music for a single mediaeval composer, largely in part due to his own efforts to preserve and curate manuscripts for his music. The dominant figure of the ars nova style in late medieval music, Machaut is regarded as the most significant French composer and poet of the 14th century and often seen as the century's leading European composer.
