Johann Christoph Friedrich Bach (June 21, 1732--January 26, 1795), the ninth son of Johann Sebastian Bach, sometimes referred to as the "Bückeburg Bach".
Born at Leipzig, Germany, he was taught music by his father. He studied at the St. Thomas School, and some believe he studied law at the University there, but there is no record of that. In 1750 Count Wilhelm of Schaumburg-Lippe appointed Johann Christoph harpsichordist at Bückeburg, and in 1759 becoming Konzertmeister. While there, Bach collaborated with Herder.
Bach wrote keyboard sonatas, Symphonies, oratorios, liturgical choir pieces and motets, operas and songs. Because of Count Wilhelm's predilection for Italian music, Bach had to adapt his style accordingly, but he retained stylistic traits of the music of his father and of his brother, C. P. E..
He educated his nephew Wilhelm Friedrich Ernst Bach in music as his own father had, and Wilhelm Friedrich Ernst went on to become music director to Frederick William II of Prussia.
The 1911 Encyclopedia Britannica says of him "He was an industrious composer, ... whose work reflects no discredit on the family name." Professor Peter Schickele, in comparing his alter ego, the fictitious composer P. D. Q. Bach, to Johann Sebastian's other sons, said that P. D. Q.'s music has "the obscurity of Johann Christoph Friedrich."
