Le Miroir de Musique is an ensemble specialising in the music of the late middle ages and Renaissance, from the golden age of the troubadours to the humanist movements of the 16th century. The ensemble is based in Basel and brings together the most prolific of early music performers, many of whom are graduates of the Schola Cantorum Basiliensis.

The image of a 'Mirror of Music' is borrowed from Jacques de Liège’s treatise (Speculum Musicae), and reflects their goal of painting a vivid picture of medieval and Renaissance music, in a spirit of fidelity to the original sources.

This project was first conceived for the Festtage Alter Musik in Basel in 2013, at the suggestion of Peter Reidemeister. The programme was developed in close collaboration between the five musicians and the musicologist Martin Kirnbauer.
