High Quality Content by WIKIPEDIA articles! 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 to the great age of those two composers.
