Brass band is a musical genre which employs brass and percussion instruments. It differs from a marching band in that a brass band does not have woodwind instruments, such as saxophones, oboes, flutes, fifes and bassoons.

While brass bands and drum and bugle corps are both musical genres which are defined by the use of instruments classed as brass and percussion, the two genres differ as follows. A brass band:

-- may or may not have an honor guard -- a drum and bugle corps must have an honor guard;
-- may or may not observe patriotic or historically military traditions and values as a drum and bugle corps must (this is due to the often strictly civilian nature of band instruments as opposed to the purely military history of drums and bugles as signalling weapons);
-- is focused first on instrumentation and the playing of instruments, not (always) first being a fraternal group, as drum and bugle corps are;
-- plays band instruments in a variety of keys - drum and bugle corps use single key brass instruments throughout their hornline;
-- may or may not play outdoors or march - while a few drum and bugle corps may be organized as a "concert" or non-marching group, they still only perform with marching outdoor instrumentation; and
-- identifies with and honors band people and band history, while drum and bugle corps identify with and honor drum and bugle corps history, all other outside musical genres being optional and less vital than one's own genre.

Some categories of brass bands, such as traditional British brass bands, observe strictly regulated rules regarding size and type of instrumentation.
The brass band marched from the parade route into the center of the park, and performed a wonderful summer concert for the community.

Reggie: I clowned that bitch...after the Cleveland Steamer she ate my ass and then followed it up with a Rusty Trombone!

Terence: That's some shit...sounds to me like a Cleveland Brass Band son.

The rare occurrence where two males engaged in docking are simultaneously being stimulated via the art of tromboning
At the orgy, Pete and John were trying out a new docking technique and two random blokes started tromboning them at the same time! That's a real NASA Brass Band event!
