Johann Abraham Peter Schulz (31 March 1747 – 10 June 1800) was a German musician.
He is best known as the composer of the melody for Matthias Claudius's poems "Der Mond ist aufgegangen" and "Wir pflügen und wir streuen", and the Christmas carol "Ihr Kinderlein kommet".
[1] In 1768 Kirnberger recommended Schulz for the position of music teacher and accompanist to the Polish Princess Sapieha Woiwodin von Smolensk.
He served as the conductor of the French Theatre in Berlin from 1776 to 1780 and from 1780 to 1787 he was the Kapellmeister of Prince Henry in Rheinsberg.
Schulz wrote operas, stage music, oratorios, and cantatas, as well as piano pieces and folk songs; he also wrote articles on music theory for Johann Georg Sulzer's (1720–1779) Allgemeine Theorie der schönen Künste in four volumes.
