Benny Goodman developed an interest in classical muisc and recoded the Mozart Clarinet Concerto and Clarinet Quintet. He also commissioned Bela Bartok to write "Contrasts", for clarinet, violin and piano which he premièred with the composer and the violinist Joseph Szigeti. However, this question doesn't really make sense. It is important to read over things after you have written to check that they express clearly what you mean. Names of people and places, etc. should begin with a capital letter.
