The trombone is an orchestral brass aerophone with a tenor or bass range.


The trombone is a medium-size cylindrical brass aerophone with a fairly low range . It is a mainstay of the brass section of orchestras, marching bands, and jazz bands. The feature that sets the trombone apart from other common Western instruments is its slide.

A bass trombone

This bass trombone has valves and extra tubing to help it get the lowest notes, as well as the moveable slide (out in front of the bell) common to all trombones.

The instrument

Like other orchestral brass , the trombone has a mouthpiece , a main body of tubing, and a bell. The basically cylindrical shape of the trombone's tubing (as opposed to the more conical baritones and tubas) gives the trombone a clear, direct, brassy sound that is very popular in jazz and band music.

The instrument changes pitch using a moveable section of tubing called the slide . As the slide moves out, the instrument gets longer, and the sound gets lower. You might be tempted to think this means that there is one note available for any possible position of the trombone's slide, but this is not the case. Most possible placements of a trombone slide give pitches that sound wrong or out of tune, because they fall in between the notes of the chromatic scale . These in-between notes are only used when the trombone plays a glissando , sliding between the notes on purpose. There are seven slide positions that do give scale notes. Having the slide all the way in is position 1; having the slide all the way out is position 7. The other positions are spread out in between, with several inches between one position and the next.

But of course, the trombone can get more than seven notes. Like the brass instruments that only have a few valves (trumpet and horn, for example), the trombone can use changes in the player's embouchure to get many different notes from a different harmonic series at each position.

The trombone can play many different notes in each slide position; the figure shows only the lowest six notes possible for first and seventh positions. Each position gives the player a different harmonic series of possible notes to play.

Seven positions, each a half step apart, will cover a tritone (about half an octave). This is plenty everywhere in the trombone's range, except at the very bottom, in between the fundamental and the second harmonic, which are a whole octave apart. So some trombones - especially bass trombones - have an extra length of tubing opened by a valve (called the plug or trigger ) that allows them to play the rest of that lowest octave. (If you want or need to understand this paragraph, and don't, please see Harmonic Series .)

Before valved brass were common, trombones were widely available in a variety of sizes (see below ), but most of these are now rare. The soprano trombone, for example, plays in the same range as the modern trumpet , which has replaced it in most ensembles. Also rare are the sopranino trombone, which is even smaller and higher than the soprano, and the piccolo , the highest of all. The instrument that is now commonly called "the trombone" is the tenor trombone , which sounds one octave lower than the soprano/trumpet range . The trombone section of most orchestras and bands will also have at least one bass trombone , which has a deeper sound, a slightly lower range than the tenor, and a fuller, more focussed sound on low notes. The alto , which is smaller and higher than the tenor, but not as high as the soprano, and the contrabass , which sounds even lower than bass, are now rarely played.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
