Johann Friedreich Doles (b. 1715–d. 1797). 

Johann Friedrich Doles began his musical studies at age 12. In 1739, at age 24, he enrolled at Leipzig University, where he studied with J. S. Bach. Doles became the kantor of Freiburg in 1944 and was later appointed the kantor of Leipzig Thomaskirche, where he remained until 1789. He composed over 160 cantatas and more than 35 motets.  His choral works often featured an ornamented solo on a biblical text over a chorale setting in even note values. Sometimes criticized for departing from Bach’s style, Doles sought to simplify music to make it more accessible to untutored listeners—although ironically his compositions were filled with frills. He greatly enlarged the collegium musicum in Leipzig by adding a number of public performances, which allowed many more people to attend concerts.
