As the title suggests, this piece comprises a set of variations on an original chorale, which is presented in the opening bars. The chorale uses the dark middle and lower sections of the band and is extended with minor variations until a pause leads to the first real variation, marked Vivo, in the form of a moto perpetuo. The second variation is a beautiful andante introduced by a solo clarinet. Following a full band climax, the final variation opens with quiet, nervous energy until its main theme is introduced. The chorale makes a brief appearance until the main theme reappears. This leads to a triumphant final augmented statement of the chorale theme, decorated by the florid clarinet theme in the upper woodwinds. A dazzling concert work. |
