What is a trombone?

The trombone is an old and important member of the brass instrument family. The trombone has been around in some form since the 1500s, developed from early trombones it was originally known as a sackbut.

By far the most common type of trombone is the modern Bb tenor trombone. This instrument was first produced about 1700 and apart from bore and bell size hasn’t really changed that much since.

Nearly every trombone player begins their journey on a Bb tenor trombone. The tenor trombone can be found playing in various musical styles and ensembles including classical, jazz, rock, pop, and folk music.

How does a trombone work?

The trombone plays in concert pitch: when the trombone player plays a written C, the note that comes out is the same as a C on the piano. 

Unusually, the trombone is written in many clefs, but most players begin their journey in the bass clef, playing notes that look and sound like the notes played by the left hand on the piano. 

The only real exception to this is in British Brass Bands, where the tenor trombone plays in Bb treble clef; as long as the player plays brass band music, this isn’t a problem, but other ensembles tend to stick to concert pitch in C bass clef.

Making a buzz

All brass instruments work by the player buzzing their lips together into a mouthpiece, which in turn vibrates the air inside the instrument creating a sound. All brass instruments are basically empty tubes that you can change the length of. On any tube length, you can play a pattern of different pitches or notes by changing your buzz using your lips and the controlling air you blow through them.

You will have heard this pattern played by bugle calls; this is known as the harmonic series, sometimes called partials, and whatever length of tube you choose the pattern remains the same. With the trombone, every time you add more tubing with the slide this pattern becomes lower in pitch so by choosing a tube length and a harmonic you can play all the notes you’ll ever need…with practice!

What are the different types of trombone?

As well as the Bb tenor trombone the broader trombone family is much larger than you might at first realize, with instruments of all sizes and some specialized for specific genres.

The Trombone section

Trombones and their players are known for their gregarious nature and are usually found in sections! In most bands this will take the form of two tenors and a bass trombone and in a jazz genre big band, three tenors and a bass. Sometimes, especially when accompanying choral music, an orchestral section will have an alto, a tenor, and a bass and will spend most of the piece supporting the choir’s singers.

Of course, there are plenty of times when there is only one trombone player like in a jazz combo or rock/pop band horn section. Sometimes music theatre productions only have one trombone player and quite often this takes the form of a bass trombone player.

The Trombone Family

The B♭tenor, slide trombone is by far the most popular trombone and the one most players begin learning how to play trombone on. Like all brass instruments however, the B♭tenor trombone is part of a whole family of trombones ranging from the tiny sopranino trombone, which is a quarter the length of a B♭tenor to the big contrabass trombone which is up to twice as long as the normal B♭instrument. Some trombones use piston valves (like the B♭trumpet) and are called valve trombones and others have short, round rotary valves either instead of the hand slide or to augment the tube length options, but they all do the same job, adding tubing.

Musical Vocabulary

Music terminology for beginners

Pitch

How high or low a sound is. Usually shown as a letter: A-G and by where the written note is placed: higher or lower on the music stave or staff.

Duration

How long or short a sound is. Measured in beats and shown by the shape of a written note.

Beat

How to measure and describe the passing of time in music, the heartbeat or pulse of the music, what you tap your toe, march, or dance to. Measured in beats per minute (BPM) or expressed in an Italian term such as Presto (fast), Andante(walking pace), or Largo (slow).

Stave or Staff

The familiar horizontal lines that written music is placed on. Think of this like a ladder: the higher the note has climbed the higher the pitch it represents.

Clef

A symbol at the beginning of the music that tells us which pitch belongs on which line of the staff or stave. On trombone, we use the treble or G clef which means the second line is where the note G lives.

Bars and bar lines

Vertical lines on the staff or stave, bar lines help us organize time by dividing the horizontal format of the music into bars.

Time signatures

These numbers at the beginning of a piece of music tell us how many beats are in each bar (top number) and what type of note each beat is made from (bottom number). i.e. 44 – four crotchet beats per bar.
