The volume for intermediate players in the Ad libitum series offers duos from the Renaissance to the Late Romantic Period, which can be performed in a varied ensemble of instruments. The publication also contains works by less well-known composers, including two pieces by Bertalotti which were originally written for solfege yet are valuable as concert pieces and can be well played, as well as a composition by Jacques-Christophe Naudot and one by Carl Friedrich Weidemann.
