Woodwind Instruments

The woodwind instruments are one of the four families of the orchestra and the melodic heart of the concert band. What unites them is not the material (the saxophone is made of brass and still belongs to this family) but how they produce their sound: by making the air inside a tube vibrate with an edge or a reed. Here you will find which they are, how they are classified and a comparison chart, with a link to the interactive guide to each one (fingerings and real sound) so that you can see and hear the differences.

On this site every instrument of the family has its own page with an interactive fingering chart, range and real sound. This page is the overview; from here you can go to each one.

The most common woodwinds in the band and the orchestra are the piccolo, the flute, the oboe, the E♭ clarinet, the B♭ clarinet, the saxophone, the English horn (UK: cor anglais), the bass clarinet, the bassoon and the contrabassoon:

What is a woodwind instrument?

It is an aerophone (it sounds through a column of air) in which that column is set vibrating in one of two ways: by blowing against an edge (a sharp rim, like blowing across the mouth of a bottle) or by making a reed of cane vibrate. That is the whole definition, and it is the source of a classic misunderstanding:

The name “woodwind” is historical, not a description of the material. The modern flute is made of metal and the saxophone has always been made of brass, but both are woodwinds because they sound by an edge and by a reed. In the brass family, by contrast, the sound starts with the vibration of the player's lips. In short: what classifies an instrument is not what it is made of, but how its sound starts.

The three ways of producing sound

The family has three sub-groups according to the mouthpiece. It is the most useful classification, because instruments in the same group are alike in technique and tone color:

GroupHow the sound is producedInstruments
EdgeThe air strikes a sharp edgeFlute, piccolo
Single reedOne cane blade on the mouthpieceClarinet, bass clarinet, saxophone
Double reedTwo cane blades vibrating against each otherOboe, English horn, bassoon, contrabassoon

1. Edge (no reed)

The air strikes a sharp edge. This is the flute family: a clean, agile sound, and they are the only woodwinds that have no reed.

  • Flute — the agile high voice of the band.
  • Piccolo — the small flute; it sounds an octave higher and crowns the tutti.

2. Single reed

A single blade of cane vibrates against the mouthpiece. A warm, very flexible tone color; this is the largest group in the band. The clarinets form a whole family, from the E♭ clarinet to the contrabass clarinet: see the types of clarinet. The saxophones are another: the types of saxophone.

  • E♭ clarinet (in Spanish, requinto) — the small, high clarinet, the bright voice of the band.
  • B♭ clarinet — the “violin of the band”: it carries the melody and is usually the largest section.
  • Bass clarinet — the low voice of the clarinet, deep and velvety.
  • Saxophone (soprano, alto, tenor and baritone) — a whole sub-section of its own; they share the same fingering.

3. Double reed

Two tied blades of cane vibrate against each other. A nasal, unmistakable tone color, very expressive.

  • Oboe — a penetrating high voice; it gives the tuning A.
  • English horn — the alto of the oboe, lower and more melancholy. (Despite its name it is neither English nor a horn; it is an oboe pitched a fifth lower.)
  • Bassoon — the double-reed bass, warm and at times comic.
  • Contrabassoon — the lowest voice of the whole family, an octave below the bassoon.

Woodwinds in the band and in the orchestra

These instruments appear in both of the great ensembles, the symphony orchestra and the concert band, but with a very different role in each, and many sources tell only half of the story (the orchestral half):

  • In the orchestra the woodwinds are a small section of color: normally two of each instrument (2 flutes, 2 oboes, 2 clarinets, 2 bassoons), who provide solos and characteristic tone colors over the foundation of the strings. The saxophone hardly ever appears.
  • In the band the woodwinds are the melodic core. The clarinet plays the part the violin plays in the orchestra: it carries the melody and is the largest section, divided into several parts (first, second, third). The saxophones form a complete section (altos, tenors, baritone) that gives body to the inner voices, and the flutes, oboe and bassoon complete the group.

This double life matters a great deal in Spain, and especially in the Valencian Community with its hundreds of music societies, where the band is the way in for most wind players. That is why a woodwind player needs exactly what these guides bring together: fingerings, reading and transposition for each instrument.

Comparison chart of the woodwind instruments

From highest to lowest, with mouthpiece type, pitch and written range. Many of them transpose (they sound a different note from the one they read): in those cases the chart says by how much.

Pitches use scientific pitch notation (C4 is middle C; see the acoustic index). Click any instrument to see its range register by register, its fingerings and to hear its real sound. The four saxophones share the same fingering and the same written range (B♭3–F♯6) and differ only in how much they transpose; you will find them in depth in the saxophone guide. The ranges given are the usual written ranges; advanced players can go beyond them at the top.

Why do many of them transpose?

A transposing instrument sounds a different note from the one written, so that the same player can switch between instruments of different sizes without relearning the fingerings: the player reads and fingers the same way, and the tube takes care of the rest. This is why a clarinetist moves from the clarinet to the bass clarinet, or a saxophonist from the alto to the tenor, reading the same notes. The flute, oboe and bassoon are in C and do not transpose (except the piccolo and the contrabassoon, which sound an octave higher and an octave lower respectively). We explain it in depth in each guide and in the index of notes by instrument.

A little history

The woodwinds are among the oldest families: there are prehistoric bone flutes tens of thousands of years old, and reed instruments have accompanied music since Antiquity. The family as we know it took shape mainly between the Baroque, which gave the transverse flute, the oboe and the bassoon their form, and the 19th century, when Theobald Boehm revolutionized the key system of the flute (which then passed to the clarinet) and Adolphe Sax invented the saxophone around 1840. The clarinet had appeared a century earlier, around 1700, thanks to Johann Christoph Denner.

In summary

  • “Woodwind” classifies by how the sound is produced (edge or reed), not by material: that is why the saxophone, made of brass, is a woodwind.
  • Three sub-families: edge (flute, piccolo), single reed (clarinet, bass clarinet, saxophone) and double reed (oboe, English horn, bassoon, contrabassoon).
  • In the concert band they are the leading voice: the clarinet plays the “violin” role and the saxophones form a section of their own.
  • Several of them transpose; each guide has an interactive fingering chart, range and real sound.

Frequently Asked Questions

What are the woodwind instruments?
Flute, piccolo, oboe, English horn, clarinet, bass clarinet, saxophone, bassoon and contrabassoon. They are grouped by how they produce sound: edge (the flutes), single reed (clarinets and saxophones) and double reed (oboe, English horn, bassoon and contrabassoon).
Why are the saxophone and the flute woodwinds if they are made of metal?
Because “woodwind” classifies by how the sound is produced, not by material. The flute sounds by an edge and the saxophone by a single reed, like the clarinet. In the brass family, by contrast, the sound starts with the vibration of the player's lips. The name of the family is historical: originally these instruments were made of wood.
What role do woodwinds play in the band and in the orchestra?
In the orchestra they are a small section of color, normally two of each instrument, providing solos and tone colors over the strings. In the concert band they are the melodic core: the clarinet is the largest section (it plays the part of the violin) and the saxophones form a section of their own. In the Spanish band tradition, especially the Valencian one, the woodwinds are the protagonists.
What is the difference between single reed and double reed?
A single reed is one blade of cane that vibrates against the mouthpiece (clarinet, saxophone). A double reed is two tied blades that vibrate against each other, with no mouthpiece (oboe, English horn, bassoon, contrabassoon). The double reed gives a more nasal, penetrating tone color.
