Georg Andreas Sorge (21 March 1703 in Mellenbach, Thuringia – 4 April 1778) was an organist, composer, and, most notably, theorist.
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 1⁄12 comma as an indivisible unit of measure.
He cited Bach as 'witness' that regular 1⁄6-comma meantone temperament was inadequate to 'modern' harmony, and he dismissed Johann Philipp Kirnberger's schemes of temperament as 'no good'.
