The French composer Charles Koechlin is one of the most interesting composer personalities of his time. Highly regarded in professional circles and consulted as a teacher and advisor by figures such as Darius Milhaud and George Gershwin, he never held any official positions. He was an uncomfortable contemporary who, due to his drive for freedom and independence, never allowed himself to be co-opted by any movements. Koechlin was deeply convinced that the style of a composition should always be chosen according to the individual expression of the composer, as the composer always has "something to say" with their music. Therefore, his music cannot easily be categorized into a stylistic box. Nevertheless, there is at least one specific characteristic of his work: the extremely nuanced orchestration. This work is dedicated to the orchestrator Koechlin.
