Marianne Rônez was born in Berne, Switzerland. She began to study violin there with Ulrich Lehmann. She completed her studies at the Hochschule für Musik in Vienna with Josef Sivo. There she also met Josef Mertin, who gave her many ideas for performing early music. Since then she has done a lot of work with the baroque violin and the viola d’amore. Together with Ernst Kubitschek she founded the ensemble Affetti Musicali that has given many concerts throughout Europe and USA. As a soloist, her favorite areas of early violin playing are the music of Biber and his south German contempories, J. S. Bach and W. A. Mozart. The viola d’amore repertory includes music from the 17^th century until today, and more than one modern composer has dedicated works to her.

Marianne Rônez has done much research work on the history of violin technique. Of course, the knowledge she has gained influenced her violin playing. So she plays the German violin music of the late 17^th century with the French bow grip, with the thumb under the hairs, which gives this music a very clear and special sound. She is regularly invited to give papers at congresses about violin playing of the 17^th and 18^th centuries; many publications by Marianne Rônez exist about it. She has also published papers and given lectures about the history of the viola d’ amore.
She regularly holds master classes and workshops for violin and viola d’amore and performs with the chamber music group Affetti Musicali throughout Europe, the United States, and in Korea. She also performs as a soloist and with other groups, and has made many recordings for radio stations.
