Biber and Vejvanovský already knew each other from their education at the Jesuit College in Troppau, Silesia, and both musicians came to the episcopal court in Kroměříž.

While Biber did not return from a business trip without permission after only a short time and made a career as a violinist in Salzburg, Vejvanovský remained in Kroměříž for the rest of his life and worked there as a Kapellmeister. The fruitful collaboration between the two musicians led to a series of chamber music works in which the trumpet is used on an equal footing with the violin.

These works show that Vejvanovský must have been an outstanding trumpeter, for in his time the only instrument available was the natural trumpet, in which the player had to produce all the notes with his lips alone. In these pieces, the trumpet sometimes plays in keys in which not all the notes are contained in the trumpet's natural tone row.

Jean-François Madeuf is one of the very few trumpeters today who have mastered playing on the natural trumpet (without auxiliary holes) and presents this special repertoire from Kroměříž/Salzburg on this instrument for the first time.
