c. 1665

In Germany, Matthias Weckmann writes a set of 10 instrumental sonatas for the Hamburg Collegium Musicum. All but one of the sonatas designate trombone. All but two of the sonatas are scored for four instruments and continuo. The most common combination in the set is cornettino, violin, trombone, bassoon, and continuo. Alternates are given for many of the parts (Collver 73).
