Henri-Gustave Casadesus was a French musician and composer. He came from the Casadesus family of musicians and was the uncle of the pianist Robert Casadesus.
Well-known works: Viola Concerto in D major after Carl Philipp Emanuel Bach. Henri, on the other hand, is the author of a viola concerto in D major attributed to Carl Philipp Emanuel Bach. This concerto appeared in a Russian edition in 1911, supposedly "transcribed.... for small orchestra by Maximilian Steinberg," and was subsequently performed by conductors such as Darius Milhaud and Sergei Kusevitsky and recorded by Eugene Ormandy.
Concertos in the style of Handel, Boccherini and Johann Christian Bach: Henri Casadesus is also considered the author of a concertante symphony for viola d'amore, double bass and orchestra, as well as two viola concertos in the style of George Frideric Handel (in B minor), Johann Christian Bach (in C minor) and of a violin concerto in the style of Luigi Boccherini (in D major)[4]. He composed several operettas (Le Rosier, Sans tambour, ni trompette, La petite-fille de madame Angot, Cotillon III) and film scores (Le gardian, Les mystères de Paris, Paris-New York). He also wrote a method for learning the viola d'amore and 24 etudes (1931) for this instrument.
