Lambert Massart Lambert Massart Joseph Lambert Massart (19 July 1811 – 13 February 1892) was a Belgian violinist who has been credited with the origination of the systematic vibrato. He compiled "The Art of Working at Kreutzer's Etudes," a supplement that contains 412 fingerings and bowings taken from his time studying with Rodolphe Kreutzer. He was an excellent String quartet player who gave many delightful chamber concerts, having also played Beethoven's "Kreutzer Sonata" in A minor with Franz Liszt on 23 May 1843. Massart was born in Liège, and was taught music first by his father Joseph Marie and later by his
Joseph Kreutzer that he is still being performed and recorded today. Joseph Kreutzer Joseph Kreutzer (11 November 1790 – 16 June 1840) was a German composer, conductor, guitarist, and violinist. Kreutzer was born in Aachen, the son of a local music teacher. He lived in Düsseldorf from about 1805, where he established himself among the leading musicians of the city. He is known to have been a violin teacher to Norbert Burgmüller and probably concert master at the local theatre for a time. He died in Düsseldorf. His compositions consisted mostly of chamber music and instructive pieces for bowed strings and guitar.
