1647—Vienna, Austria
In his motet, Cantate gentes, Giovanni Valentini calls for 7-part choir, along with an instrumental ensemble of 3 cornetti, violetta, viola, 2 trombones, and organ. The ensemble plays an introductory sonata and interludes between the 4 verses of the motet. Valentini indicates optional substitutions for 3 of the parts: “Piffaro o Cornetto tertio,” “Alto Trombone o Violetta primo,” and “Viola o Trombone secondo” (Saunders, The Hapsburg Court of Ferdinand II).
