Simon Sechter (11 October 1788 – 10 September 1867) was an Austrian music theorist, teacher, organist, conductor and composer. He may have been the most prolific composer who ever lived, outdoing even Georg Philipp Telemann in the quantity of his output.[citation needed]
Carl Christian Müller (1831–1914) compiled and adapted Sechter's Die richtige Folge der Grundharmonien as The Correct Order of Fundamental Harmonies: A Treatise on Fundamental Basses, and their Inversions and Substitutes (Wm. A. Pond, 1871; G. Schirmer, 1898).
Sechter was born in Friedberg (Frymburk), Bohemia, then part of the Austrian Empire, and moved to Vienna in 1804, succeeding Jan Václav Voříšek as court organist there in 1824. In 1810 he began teaching piano and voice at an academy for blind students. In 1828 the ailing Franz Schubert had one counterpoint lesson with him. In 1851 Sechter was appointed professor of composition at the Vienna Conservatory. He died in poverty. He was succeeded at the Conservatory by Anton Bruckner, a former student whose teaching methods were based on Sechter's. (Hide extended text)...(Read all) Source : Wikipedia
