Arrangement

In music, an arrangement is a musical reconceptualization of a previously composed work. It may differ from the original work by means of reharmonization, melodic paraphrasing, orchestration, or development of the formal structure. Arranging differs from orchestration in that the latter process is limited to the assignment of notes to instruments for performance by an orchestra, concert band, or other musical ensemble. Arranging "involves adding compositional techniques, such as new thematic material for introductions, transitions, or modulations, and endings.... Arranging is the art of giving an existing melody musical variety".

Classical music

Arrangements and transcriptions of classical and serious music go back to the early history of this genre. In particular, music written for the piano has frequently undergone this treatment. The suite of ten piano pieces Pictures at an Exhibition, by Modest Mussorgsky, has been arranged over twenty times, notably by Maurice Ravel.

Due to his lack of expertise in orchestration, the American composer George Gershwin had his Rhapsody in Blue orchestrated and arranged by Ferde Grofé.

Concert band

A concert band, also called wind ensemble, symphonic band, wind symphony, wind orchestra, wind band, symphonic winds, symphony band, or symphonic wind ensemble, is a performing ensemble consisting of members of the woodwind, brass, and percussion families of instruments, along with the double bass.

A concert band's repertoire includes original wind compositions, transcriptions/arrangements of orchestral compositions, light music, and popular tunes. Though the instrumentation is similar, a concert band is distinguished from the marching band in that its primary function is as a concert ensemble. The standard repertoire for the concert band does, however, contain concert marches.

History

In the 18th century, military ensembles were doing double duty as entertainment at the royal courts, either alone or combined with orchestral strings. Composers such as Mozart were writing chamber music for these groups, called Harmonie bands, which evolved to a standard instrumentation of two oboes, two clarinets, two horns, and two bassoons. In addition to original compositions, these groups also played transcriptions of opera music.
