Composer, organist, teacher and Austrian theoretician. From the age of 7 he/she was Chorister in Klosterneuburg (Vienna), his hometown. He/She studied at Melk between 1749 and 1754 and later in his native Vienna. After serving as an organist in several churches, was named Assistant to Leopold Hofmann in St. Stephen's Cathedral in Vienna, happening in 1793 as "kapellmeister", where he/she served until his death in 1809. Remembered universally as the teacher of Beethoven (who taught counterpoint from 1794 to 1795, was admired by Mozart and Haydn as the first organist of his day.) I knew perfectly before their time music, which decisively influenced his own ecclesiastical compositions, which include thirty-five masses. He/She was also prolific in his orchestral works and Chamber, which include symphonies, string quartets and sonatas. In his works for keyboard, there are numerous leaks, one of which was attributed for a long time to J. Sebastian Bach. Best known for his theoretical writings as for his compositions, he/she was the author of important texts on composition (1790) and under encryption (1791) that even came to be translated into French and English.
