No known evidence exists detailing the exact origin on music, but it is probable that music served many functions. Religious leaders used music to create a crowd contagion that enhanced the religious service. A good example from the European tradition, J.S. Bach received sole support writing and playing for the Christian church in Germany, allowing him to generate a large body of music. Business people soon learned that “singing” their items for sale attracted many more customers to their open air market store. What we call a commercial jingle today was one of the earliest forms of music, and the best singers and songwriters were soon hired by the wealthiest merchants to increase sales.  Musicians have a long tradition of playing for tips at public meeting houses and restaurants.  Unfortunately this sometimes resulted in the musicians being fed drinks and becoming alchoholics.
