Introduction and Allegro (Ravel)

Introduction and Allegro for Harp, Flute, Clarinet and String Quartet () was written by Maurice Ravel in 1905. It premiered on 22 February 1907 in Paris.
Background.
To showcase its new chromatic harp, the Pleyel company commissioned Claude Debussy in 1904 to write his "Danse sacrée et danse profane" for harp and orchestra. The Érard company responded by commissioning Maurice Ravel to write a piece to display the expressive range of its double-action pedal harp. Ravel completed his "Introduction and Allegro" for a septet of harp, flute, clarinet and string quartet in June 1905, dedicating it to Albert Blondel, director of Maison Érard. He wrote it at breakneck speed, as he had to complete it before embarking on a boating holiday with friends.
Ravel omitted the "Introduction and Allegro" from the catalogue of his works, made no mention of it in his autobiography, and referred to it in only two of his letters. Nevertheless, it was often performed at his concerts and it was the very first of the small number of his own works that Ravel recorded (1923; Gwendolen Mason, harp; Robert Murchie, flute; Haydn P. Draper, clarinet.)
In 1906 Ravel wrote a version for two pianos. In a letter to Désiré-Émile Inghelbrecht on 26 February 1911, Ravel sanctioned the work being arranged for larger forces.
Description.
It is written in the key of G-flat major and it is the first piece to explore and exploit the full resources of the solo instrument. It is sometimes described as a miniature concerto, but it is more usually classified as a genuine chamber music work.
The "Introduction" and the "Allegro" are played without a break. The Introduction, "Très lent", takes only 26 bars. The Allegro in a modified sonata form begins with the solo harp expanding the material presented before. The woodwinds expose a second theme, accompanied by pizzicato. After a fortississimo climax in the development, a harp cadenza leads to a "straightforward" recapitulation and a close "without extensive fireworks or bombast of any kind". The work takes about 11 minutes to perform.
