Of the many trio sonatas written during the 150-year history of this genre the set composed in 17212 by Jan Dismas Zelenka (16791745) is certainly among the most striking and unusual. Extreme both in their dimensions and their demands on performer, they unite sophisticated formal designs with exhilarating virtuosity.

These sonatas appeared in print for the first time three decades ago in the series Hortus Musicus edited by Camillo Schoenbaum , a pathbreaking publication that ushered in the current Zelenka renaissance. Since then recent discoveries and analyses of the sources have made a new edition necessary in order to create a performing version that meets scholarly standards.
