The brass section usually includes trumpets or cornets; French horns, alto horns, or mellophones; tenor trombones; baritone horns or euphoniums; and tubas or sousaphones. E♭ soprano cornets are sometimes used to supplement or replace the high woodwinds, while the mellophone often is used in place of the French horn. Some especially large bands use flugelhorns and bass trombones. Specially designed versions of the lower brass have been created for use while marching. These are typically wrapped in such a way that allows the bell to face toward the audience at all times. Bands may also modify their instrumentation to remove slide trombones completely and replace them with another instrument, such as a valved trombone or marching baritone horn.
