Georg Andreas Sorge
Georg Andreas Sorge (21 March 1703 in Mellenbach, Thuringia – 4 April 1778) was an organist, composer, and, most notably, theorist. His references to Johann Sebastian Bach show that they were friends, and he composed three fugues for organ on the name BACH ( BWV Anh. 107, 108 and 110). He joined Lorenz Christoph Mizler's Corresponding Society of Musical Sciences in 1747, just a month after Bach himself. Sorge's writings on thorough-bass and harmony are very competent, and his theoretical grasp of unequal temperaments excelled even that of J. G. Neidhardt (though still taking comma as an indivisible unit of measure. He cited Bach as 'witness' that regular -comma meantone temperament was inadequate to 'modern' harmony, and he dismissed Johann Philipp Kirnberger's schemes of temperament as 'no good'.Boyd, Malcolm.

Meantone Temperament
Meantone temperaments are musical temperaments; that is, a variety of Musical tuning#Tuning systems, tuning systems constructed, similarly to Pythagorean tuning, as a sequence of equal fifths, both rising and descending, scaled to remain within the same octave. But rather than using perfect fifths, consisting of frequency ratios of value 3:2, these are ''tempered'' by a suitable factor that narrows them to ratios that are slightly less than 3:2, in order to bring the major or minor thirds closer to Just intonation, the just intonation ratio of 5:4 or 6:5 , respectively. Among temperaments constructed as a sequence of fifths, a regular temperament is one in which all the fifths are chosen to be of the same size. Twelve-tone equal temperament () is obtained by making all semitones the same size, with each equal to one-twelfth of an octave; i.e. with ratios . Relative to Pythagorean tuning, it narrows the perfect fifths by about 2 cents (music), cents or of a Pythagorean co ...

Schübler Chorales
' ( 'six chorales of diverse kinds, to be played on an organ with two manuals and pedal'), commonly known as the ''Schübler Chorales'' (), BWV 645–650, is a set of chorale preludes composed by Johann Sebastian Bach. Johann Georg Schübler, after whom the collection came to be named, published it in 1747 or before August 1748, in Zella St. Blasii. At least five preludes of the compilation are transcribed from movements in Bach's church cantatas, mostly chorale cantatas he had composed around two decades earlier. The fact that Bach had gone to the trouble and expense of securing the services of a master engraver to produce a collection of note-for-note transcriptions of this kind indicates that he did not regard the ''Schübler Chorales'' as a minor piece of hack-work, but as a significant public statement. These six chorales provide an approachable version of the music of the cantatas through the more marketable medium of keyboard transcriptions. Virtually all ...

Kirnberger Temperament
The Kirnberger temperaments are three irregular Musical temperament, temperaments developed in the second half of the 18th century by Johann Kirnberger. Kirnberger was a student of Johann Sebastian Bach who greatly admired his teacher; he was one of Bach's principal proponents. Kirnberger's tuning systems, or ''well temperaments'' are a way to artificially splice together two arcs on the "natural" spiral of fifths to turn it into an "unnatural" circle. In Kirnberger's and his teacher Johann Sebastian Bach, Bach's time, keyboard musicians were experimenting with different unobtrusive ways to alter the spacing of notes around the spiral of fifths to close it into a circle, so that every note needed for every key signature, key was at hand, even if some rarely used key signatures might be very dissonant, but tolerable. The first Kirnberger temperament, Kirnberger I, had similarities to Pythagorean tuning, which stressed the importance of perfect fifths all throughout the ci ...

Johann Philipp Kirnberger
Johann Philipp Kirnberger (also ''Kernberg''; 24 April 1721, Saalfeld – 27 July 1783, Berlin) was a musician, composer (primarily of fugues) and music theorist. He studied the organ with Johann Peter Kellner and Heinrich Nicolaus Gerber, and starting in 1738 he studied with the violinist Meil in Sondershausen, but most significant is the time he spent from 1739 until 1741 (with breaks) studying performance and composition with Johann Sebastian Bach."Johann Philipp Kirnberger (Composer, Music Theorist, Violin, Copyist, Bach's Pupil)"
Bach Cantatas website
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
