Trombone

About the trombone...

The trombone is one of the loudest, most powerful, and resonant instruments in symphony orchestras and marching bands. The trombone belongs to the brass instrument category, is very similar to the trumpet (although larger), and is not as large as a tuba.

Context and some history

The invention of the trombone dates back to the 15th century, at the hands of an association of Flemish-type instrument manufacturers of French origin (specifically located in Burgundy). Its origin stems from the challenge of perfecting the slide trumpet.

Historically, trombones have been used in aristocratic courts, in the ecclesiastical sphere, and also in the military, before reaching orchestral music for the first time thanks to Beethoven in 1808 and other modern musical genres in which it is currently included.

Characteristics and main parts of the trombone

The trombone is generally made of metal and brass, has a tube length of approximately 3 meters and is U-shaped. However, the size of the instrument will be around 1 meter and 10 centimeters in total.

Its main parts are:

• The mouthpiece

Also called the embouchure, it is the part of the instrument where the lips must be closed so that air does not escape when playing. It is considerably large and deep compared to those used by other wind instruments.

• Tuning slide

It is located closest to the musician, is U-shaped and allows for small tuning adjustments.

• The water key

Located just on the opposite side of the tuning slide arm, mentioned above, it allows the accumulated saliva in the instrument, generated by its use, to be drained. It is a small metal piece that can be opened or closed.

• The bell

Also called the pavilion, it is another essential part of trombones. It basically allows for the resonance, amplification, and emission of sound from this musical instrument.

• The main slide

A mechanism used to manually change the pressure and length of the air column, modifying the pitch of the sound.

• The support brace

These are two transverse metal pieces that provide rigidity to the instrument and allow for a better grip for the trombonist.

• Slide lock ring

Thanks to it, the metal tubes can be connected and allow for better handling when playing, as it can be adjusted to improve the musician's experience and comfort.

The sound and musical genres of the trombone

The sound produced by the trombone is powerful and capable of musically penetrating human hearing. Its sound is associated with grandeur, impressiveness, and majesty.

It was widely used in ecclesiastical music during the Baroque and Classical periods, until it became an essential part of the symphony orchestra in the 19th century. Currently, the tenor trombone and also the bass trombone (less frequently) are usually included in the orchestra.

Other musical genres where it can be found are in marching bands, in jazz music (typical of big bands), used by soloists, and in symphonic operas.

How the trombone works

It is an aerophone instrument, and as such, it generates sounds through the vibration of air through the mouthpiece. The technique of blowing and diaphragmatic breathing
