From 1524 until his death he lived at Magdeburg, where he occupied the post of teacher or cantor in the Protestant school. The senator and music-printer Georg Rhau, of Wittenberg, was a close friend of Agricola, whose theoretical works, providing valuable material concerning the change from the old to the new system of notation, he published.
^Four other Agricolas (Alexander, died 1506; Johann, flor. 1600; Wolfgang Christoph, flor. 1630; and George Ludwig, 1643–1676) are known as composers between the end of the 15th century and the middle of the 17th.
In the 18th century Charles Burney, in the course of his tour in Germany (1772), was much impressed by Johann Friedrich Agricola (1720–1774), court composer and director of the royal chapel to Frederick the Great (Chisholm 1911).
