Always among the most innovative of composers, Arnold Schoenberg wrote several works that deliberately blur the distinction between chamber orchestra and chamber ensemble.
1) I. Ouverture
2) II. Tanzschritte
3) III. Thema Mit Variationen
4) IV. Gigue
5) Chamber Symphony No. 1 Op. 9 (Arr. A. Webern for Flute Clarinet Violin Cello Piano)
