Johann Georg Albrechtsberger (3 February 1736 – 7 March 1809) was an Austrian composer, organist, and music theorist, widely regarded as one of the leading figures in counterpoint and composition theory during the Classical period. He was a prolific composer of church music, orchestral works, and keyboard pieces, though he is best remembered for his influence as a teacher.
Albrechtsberger was a mentor to several important composers, most notably Ludwig van Beethoven, whom he instructed in counterpoint and fugue. His theoretical writings and pedagogical methods had a lasting impact on 19th-century composition, and his treatises on harmony and counterpoint remain highly regarded. He was also a friend of Haydn and Mozart.
In addition to his teaching contributions, Albrechtsberger held several prestigious positions, including Kapellmeister of St. Stephen's Cathedral in Vienna. He was a composer though his works are little performed today. Biography
Albrechtsberger was born at Klosterneuburg, near Vienna. He originally studied music at Melk Abbey and philosophy at a Benedictine seminary in Vienna, and became one of the most learned and skillful contrapuntists of his age. Albrechtsberger's earliest classmates included Michael Haydn and Franz Joseph Aumann. After being employed as organist at Raab, Hungary in 1755 and Maria Taferl, Austria in 1757, he was appointed Thurnermeister back at Melk Abbey. In 1772 he was appointed organist to the court of Vienna, and in 1792 Kapellmeister of St. Stephen's Cathedral, Vienna.
His fame as a theorist attracted to him in the Austrian capital a large number of pupils, some of whom afterwards became eminent musicians. Among these were Johann Nepomuk Hummel, Ignaz Moscheles, Josef Weigl, Ludwig-Wilhelm Tepper de Ferguson, Antonio Casimir Cartellieri, Ludwig van Beethoven, Anton Reicha and Franz Xaver Wolfgang Mozart.
