The Nonet in E-flat major, Op. 38, is an 1849 composition for chamber ensemble by French composer Louise Farrenc.
In line with the tradition established by Louis Spohr, it is scored for a combined string quartet and wind quintet: flute, oboe, clarinet, French horn, bassoon, violin, viola, cello, double bass. The double bass is sometimes replaced by a contrabassoon.
The manuscript, dated November 1849, is held at the Bibliothèque nationale de France.[1] Farrenc also arranged the Nonet for string quintet.[2] The work was not printed in Farrenc's lifetime.
