Georg Philipp Telemann
Telemann wrote instrumental music in Eisenach. He wrote concertos, overtures, and chamber music. Telemann also wrote church cantatas. After Telemann left Eisenach, Telemann still wrote music for Eisenach. He sent a cantata cycle every two years to Eisenach. A cantata cycle is a collection of cantatas. The cantatas are meant to be performed in a church year. When Duke John William died in 1719, Telemann stopped sending cantatas.
