The Sidonia-Ensemble was founded in 2012 in Bonn, Germany, and specialises in music of the Renaissance and the early baroque periods. Directed by Kerry Jago and Dorothea Jakob, early music instrumental and vocal specialists from all over Europe meet regularly in varying combinations to work together on a wide-ranging repertoire focusing mainly on the 16th and 17th centuries.

The ensemble is named after Sidonia Schein (née Hösel), the wife of the German baroque composer Johann Hermann Schein. Sidonia married the musical director of St. Thomas Church Leipzig, a predecessor of Bach in the position, in 1616, but died seven years later aged just 31 during the birth of their fifth child.
