The Emperor’s Music was composed for the brass section of the Brooklyn Symphony Orchestra. It is an antiphonal piece comprised of four groups:

I. trumpet, horn, trombone;
II. trumpet, horn, trombone;
III. trumpet, horn, bass trombone; and
IV. trumpet, horn, tuba.

The four groups should be spread across the stage as far apart as possible. This two-minute excerpt occurs a couple of minutes into the piece.
