Every brass band on the planet is built to the same blueprint: around 28 brass players plus percussion, in the same formation, like a football team where every position is loud. It’s one of music’s great level playing fields, and it means that once you know the line-up, you can watch any band from Bergen to Brisbane and know exactly who’s doing what. (In practice bands field 28-ish: an extra tuba here, a spare cornet there, and lower grade bands proudly turn up with whoever they have. The blueprint bends. More on that below.)

This is the full team sheet: every instrument in a brass band, what it sounds like, what its job is, and what kind of person ends up playing it. We’ve filmed all of them at point-blank range since 2008, so consider this insider knowledge.

The line-up at a glance

The traditional contest line-up is 28 brass plus percussion:

  • 1 Eb soprano cornet
  • 9 Bb cornets
  • 1 flugelhorn
  • 3 tenor horns
  • 2 baritones
  • 2 tenor trombones and 1 bass trombone
  • 2 euphoniums
  • 2 Eb basses and 2 Bb basses
  • 2 to 4 percussionists

That’s the ideal. On any given contest day you’ll see bands a chair or two over or under: an extra Bb bass for ballast, an eleventh cornet, a second bass trombone smuggled in. The 28-chair blueprint is the target every band builds toward, not a bouncer at the stage door.

Now let’s meet them properly, from the top of the range to the bottom.

Soprano cornet: the high-wire act

One player. One tiny Eb cornet. An entire band’s contest result resting on notes so high that dogs file complaints. The soprano sits at the end of the back-row cornets and crowns the loudest chords with the notes nobody else can reach. When a test piece ends on a blazing final chord, that gleaming edge on top is the sop.

It is widely agreed to be the most stressful chair in banding, and sop players are accordingly a special breed: part musician, part daredevil, wholly indispensable.

Bb cornets: the engine room

Nine of them, split into a front row and a back row, led by the principal cornet, who is the band’s concertmaster, star soloist and unofficial second-in-command. The principal gets the glory solos, sets the style for the whole band, and shakes the conductor’s hand on behalf of everyone else.

The cornet looks like a trumpet that’s been to finishing school: shorter, rounder, mellower. It is emphatically not a trumpet, and the difference matters enough that we wrote a whole article about it. Cornets carry most of the melody most of the time, which is why there are nine of them and why principal cornets get recognised at supermarkets by strangers. Well, in certain towns.

Flugelhorn: the velvet voice

One flugelhorn, sitting not with the cornets but with the horns, acting as the bridge between the bright top of the band and the warm middle. The flugel has the most romantic tone in the band, somewhere between a cornet and a sigh, and composers save their most heartbreaking solos for it. Flugel players know exactly how good their instrument sounds and can be forgiven their serenity.

Tenor horns: the sound you can’t place

Three tenor horns make up the true middle voice of the band, and they’re the instrument most newcomers can’t identify. Not a French horn (wrong direction, wrong shape, wrong continent of temperament), the Eb tenor horn is a neat, upright instrument with a round, gentle tone that defines the “brass band sound” more than any other section. When the band sounds like a pipe organ with a pulse, that’s the horns doing their job perfectly and invisibly.

Solo horn, the section leader, gets some of the loveliest lyrical writing in the repertoire.

Baritones: the quiet professionals

Two baritones, the least famous instruments in the band, and the section every conductor secretly relies on. The baritone is like a slimmer euphonium: lighter, more focused, less showy. Baritone players spend entire test pieces stitching the middle of the texture together, doubling everyone, rescuing everything, and receiving roughly one solo per decade, which they nail, because of course they do.

Euphoniums: the cellos of the band

Two euphoniums, and if the cornets are the band’s sopranos, the euphonium is its leading tenor. Huge, singing, generous tone, and the repertoire’s biggest lyrical moments. Composers give the euphonium the tune when they want the audience to feel something, and adjudicators give it adjectives. The principal euphonium is often the most technically dazzling player in the band, and euphonium players as a species are never allowed to forget how beautiful their instrument is, mostly because they mention it.

Trombones: the licensed rebels

Two tenor trombones and one bass trombone, the only section in the band playing with a slide instead of valves, and the only section with formal permission to be menacing. The trombones supply bite, drama and the occasional moment of pure chaos. Composers use them to signal that something serious is happening.

The bass trombone deserves its own sentence: one player, seismic sound, and a fan club in every live chat we’ve ever hosted. When the bass trombone stands up in a solo spot, our comment section becomes a scene.

The basses: the foundation

Four tubas, two in Eb and two in Bb, known in banding simply as “the basses”. They are the floor the entire band stands on, the heartbeat and the earthquake. A great bass section doesn’t just underpin the sound, it moves air you can feel through your shoes, which is why we treat audio quality as a sacred duty. Bass players are, by long tradition, the most sociable people in any band. The instrument teaches patience and teamwork; the bar afterwards teaches everything else.

Percussion: the everything section

Two to four percussionists covering timpani, drum kit, glockenspiel, xylophone, vibraphone, cymbals, and in modern test pieces, frankly, whatever the composer dreamed up: wind machines, anvils, whip cracks, thunder sheets. Modern contest percussion parts are genuinely virtuosic, and percussionists cover more ground in one piece (often literally, at a jog) than anyone else on stage.

How it all fits together

Bands sit in a horseshoe around the conductor: cornets on the left, trombones at the back right, horns and flugel in the middle, euphoniums and baritones on the right, basses across the back, percussion behind everything with room to sprint. The layout is nearly identical band to band, which is why regular viewers of our streams can find their favourite chair in any hall in the world within seconds.

The magic is in the blend. Almost every instrument above is conical bore, meaning the tubing widens gradually along its length, producing that warm, rounded, blended sound no other ensemble has. It’s also why there are no trumpets and no French horns: their brighter, edgier voices would poke out of the texture like a seagull at a choir practice. The full comparison with concert bands and orchestras explains what those ensembles do instead.

Spotting the sections on a stream

A quick field guide for your first viewing. The shiny row of small instruments facing the camera: cornets, with the principal nearest the conductor. The one player angled slightly apart at the end of that row with an even smaller instrument: the soprano, currently ageing. The upright bells in the centre: tenor horns, with the flugel tucked beside them. The bigger upright bells to the right: baritones and euphoniums, in ascending order of self-confidence. Slides at the back: trombones, plotting. The wall of enormous brass across the rear: the basses. And the people moving at speed behind everyone, playing six instruments in four bars: percussion.

Once you can read the stage, contest viewing gets dramatically better, because you’ll see a solo coming before you hear it. Our camera operators do exactly this all day, which is why our closeups arrive right on cue.

Which one should you learn?

The genuinely correct answer: whichever one your local band needs, because they’ll likely hand you the instrument for free and teach you. But as a guide: cornet if you want the tunes, euphonium if you want the beautiful tunes, tenor horn if you want to be the sound of the band, trombone if you have opinions, bass if you want friends for life, and soprano if you enjoy adrenaline and have a very understanding family. There’s a home for everyone. That’s rather the point of banding.

Frequently asked questions

What instruments are in a brass band? The traditional line-up is 28 brass players: 1 soprano cornet, 9 Bb cornets, 1 flugelhorn, 3 tenor horns, 2 baritones, 2 tenor trombones, 1 bass trombone, 2 euphoniums, 2 Eb basses and 2 Bb basses, plus 2 to 4 percussionists. Real-world bands often run a player or two over or under.

Why are there no trumpets or French horns in a brass band? Brass bands use conical-bore instruments (cornets, horns, euphoniums, tubas) whose warm tones blend into one unified sound. Trumpets and French horns are brighter and more penetrating, designed to stand out in an orchestra rather than blend in a band.

What is the hardest instrument in a brass band? By reputation, the Eb soprano cornet: one player, exposed high parts, and nowhere to hide. Principal cornet and principal euphonium chairs carry similar pressure with more solos.

What is the difference between a baritone and a euphonium? Both read the same clef and cover a similar range, but the euphonium has wider tubing and a bigger, rounder sound, while the baritone is slimmer and lighter in tone. Euphoniums get the famous solos; baritones hold the band together.

What is the biggest instrument in a brass band? The Bb bass (contrabass tuba), the largest and lowest instrument in the band. A brass band carries two of them, plus two slightly smaller Eb basses.
