Unser Mund sei voll Lachens is a church cantata by a composer born in what year?
Johann Sebastian Bach Johann Sebastian Bach (31 March [O.S. 21 March] 1685 28 July 1750) was a German composer and musician of the Baroque period. He is known for instrumental compositions such as the "Brandenburg Concertos" and the "Goldberg Variations", and vocal music such as the "St Matthew Passion" and the Mass in B minor. Since the 19th-century Bach Revival he has been generally regarded as one of the greatest composers of all time.
Johann Ernst Eberlin Johann Ernst Eberlin (27 March 1702 – 19 June 1762) was a German composer and organist whose works bridge the baroque and classical eras. He was a prolific composer, chiefly of church organ and choral music. Marpurg claims he wrote as much and as rapidly as Alessandro Scarlatti and Georg Philipp Telemann, a claim also repeated by Leopold Mozart - though ultimately Eberlin did not live nearly as long as either of those two composers.
