Joseph Schalk (24 March 1857 – 7 November 1900) was an Austrian conductor, musicologist and pianist.
He was a prominent figure in Viennese musical life of the late nineteenth-century, a vocal advocate for the music of Wagner, Bruckner and Wolf: in this capacity he was opposed to the more conservative supporters of Brahms who were led by the critic Eduard Hanslick.
[4] Schalk was involved in the preparation of several of Bruckner's scores for their first publication or performance: these include the Third[5] and Eighth[6] symphonies, along with the Mass in F Minor.
[7] Schalk wrote a series of articles under the collective title Das Gesetz der Tonalität (the law of tonality) which laid down his theory of harmony, based on his teaching from Bruckner.
Upon Bruckner's death, Schalk was named administrator of his library of music scores.
