Johann Philipp Kirnberger (also Kernberg; 24 April 1721, Saalfeld – 27 July 1783, Berlin) was a musician, composer (primarily of fugues), and music theorist. He was a student of Johann Sebastian Bach.
According to Ingeborg Allihn, Kirnberger played a significant role in the intellectual and cultural exchange between Germany and Poland in the mid-18th century (Allihn 1995, 209). 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 Lviv (then part of Poland). He spent much time collecting Polish national dances and compiled them in his treatise Die Charaktere der Taenze (Allihn 1995, 211).
Kirnberger greatly admired Johann Sebastian Bach, deeming him "the greatest of all composers." Kirnberger published Bach's Clavierübungen mit der bachischen Applicatur in the 1760s, and seeking to secure the publication of all of Bach's chorale settings, which finally appeared after Kirnberger's death; see Kirnberger chorale preludes (BWV 690–713). Many of Bach's manuscripts have been preserved in Kirnberger's library (the "Kirnberger collection").
Kirnberger is known today primarily for his theoretical work Die Kunst des reinen Satzes in der Musik (The Art of Strict Composition in Music, 1774, 1779). The well-tempered tuning systems known as "Kirnberger II" and "Kirnberger III" are associated with his name (see Kirnberger temperament), as is a rational version of equal temperament (see schisma). One of his most familiar compositions is Fuga in C-dur für Orgel ("Fanfare" Fugue), which was formerly attributed to Johann Sebastian Bach and then to his son Carl Philipp Emanuel Bach.
