Modern brass instruments include trumpet, trombone, baritone, sousaphone
(tuba), and French horn. These instruments create a wide variety of tones by the
player forcing air into the instrument causing it to resonate in different ways
(at different frequencies).
There are two different types of brass instruments, valved and slide.
Valves are used to change the shape and size of the instrument (causing the
player's wind to change its path and length, causing the instrument to resonate
in different ways). Brass instruments with valves include cornet, trumpet, and
French horn. They utilize piston valves (cornet), or rotary valves (French
horn). The musician must learn which combinations of valves produce certain
tones while using their embouchure (the position and strength of their lips on
the mouthpiece of the instrument) to make tones lower or higher in pitch. Slide
brass instruments use a slide to change the length of tubing and thus the tone
of the instrument. Most common of this type of instrument is the slide trombone.
Some brass instruments need to be transposed for piano. For example, a Bb
trumpet or an Eb alto saxophone. When the written note C is played on a trumpet,
it is the same note as an Bb on a piano. It's very important for the pianist to
be aware of this in order to communicate with the trumpet player. The same holds
true for the pianist when playing with other instruments that are tuned
differently such as a French horn or alto sax.
Music for brass ensembles (four to six brass instruments) often uses the
piano as the accompanying instrument. An experienced pianist will be able to
help with the ensemble's performance by helping them rehearse the most
challenging passages. The piano, in this case, also helps fill out the
arrangement and plays a big part in creating the rhythm of the piece. And, as
mentioned above, the pianist must be aware of the different key of each brass
instrument in order to communicate effectively with the group. For example, if
the group includes a tuba, the pianist must know whether it is a Bb or Eb tuba
in order to help rehearse the musician in the most effective way possible.
Big bands (swing, dance, and jazz) contain a number of brass instrument
and most, if not all, also include a piano. The pianist helps provides the chord
structure, rhythm, and sometimes the melody of the piece. Big band music can be
quite complex, particularly when it comes to chord structure and progressions.
Quite often, the pianist is playing the same chord as the grouped brass
instruments while at the same time contributing to the rhythm and style of the
music. A piano is also very common in jazz combos and vocal groups.
Interestingly, many brass instruments are not made of brass at all. Some,
like the French horn, are made of nickel silver or other alloys of copper, tin,
and nickel. Many brass instruments are silver plated (and they produce a
distinctive sound because of this). Although it is rare, some brass instruments
are gold plated and are prized for their appearance (more so than the somewhat
unique sound they make).
