Johann Philipp Kirnberger (24 April 1721, Saalfeld – 27 July 1783, Berlin) was a musician, composer and music theorist. He was a student of Johann Sebastian Bach. Between 1741 and 1751 Kirnberger lived and worked in Poland for powerful magnates including Lubomirski, Poninski, and Rzewuski before ending up at the Benedictine Cloister in Lvov (then part of Poland).
He became a violinist at the court of Frederick II of Prussia in 1751. He was the music director to the Prussian Princess Anna Amalia from 1758 until his death. Kirnberger greatly admired J.S. Bach, and sought to secure the publication of all of Bach's chorale settings, which finally appeared after Kirnberger's death. Many of Bach's manuscripts have been preserved in Kirnberger's library (the "Kirnberger collection").
Temperament: Werkmeister-III - Kirnberger won't be angry, will he?
