A rather unique piano trio The repertoire for piano trios is plentiful and varied. Composers such as Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig van Beethoven preferred to write for piano, violin, and cello. The repertoire for the combination of piano and two saxophones is rather limited in comparison. This is mainly to do with the fact that the instrument was first developed around 1840 by Antoine Joseph Sax, who opened a workshop in Paris in 1842 and built saxophones in seven different sizes. His patron, Hector Berlioz, was one of the first to incorporate the instrument into his orchestral compositions, and Jules Massenet used it prominently in his opera Werther in 1892, but the saxophone became more popular in French military music and, of course, in jazz, where it has been used as a solo instrument since around 1920.
