Collegium Musicum

The Collegium Musicum was one of several types of musical societies that arose in German and German-Swiss cities and towns during the Reformation and thrived into the mid-18th century.

Generally, while societies such as the (chorale) cultivated vocal music for church performance and the convivium musicum discussed musical philosophy over a banquet, the collegia musica performed both vocal and instrumental music for pleasure; they focused on instrumental music as it rose in stature during the Baroque era. Though closed amateur societies in concept, collegia frequently included professionals to fill out the music and admitted non-members to performances. Moreover, they often provided music for church, state, and academic occasions and gained the patronage of leading citizens. From the 1660s, their functions largely constituted the beginnings of public concert life in Germany. Provided by Wikipedia
