Woodwind instrument

Woodwind instruments are a specific family within the larger category of wind instruments.

They are defined by the unique way they produce sound. While many people assume they must be made of wood, this is not always true. A woodwind can be made from many different materials. These include brass, silver, gold, and platinum. Some are even made from earthen materials, such as the ocarina. The saxophone is a great example of this variety. Even though it is made of brass, it is a woodwind because it uses a reed.

The mechanism of sound production relies on moving air. Woodwinds create sound by splitting an airstream or by using reeds. In many instruments, the player blows air against a sharp edge. This action splits the air and causes an internal air column to vibrate. This vibration is what creates the musical notes we hear. This process is the fundamental way these instruments function. It distinguishes them from other types of wind instruments.

Flutes are one of the two main types of woodwinds. They are divided into open flutes and closed flutes. An open flute, like the transverse flute or panpipes, requires the player to blow across a sharp edge. This split air stream acts upon the air column inside the hollow tube. Another type is the closed flute, such as the recorder or organ pipes. In these, the player blows air into a duct. This duct acts as a channel that brings the air to a sharp edge to split it.

Reed instruments, also called reed pipes, are the second main type. These instruments focus air into a mouthpiece to make a reed vibrate. There are two subcategories: single-reed and double-reed instruments. Single-reed instruments, like the clarinet and saxophone, attach one reed to a mouthpiece using a ligature. Double-reed instruments use two small pieces of cane bound together at the base. As air is forced between these two pieces, the air column inside the instrument vibrates.

Double-reed instruments are further classified by how they are played. Exposed double-reed instruments, such as the oboe and bassoon, involve the player placing the reed directly between their lips. There are also capped double-reed instruments, like the crumhorn. In these, a cap covers the reed. The player blows through a hole in the cap to direct air to the reeds.

Bagpipes are also unique because they use two or more reeds. However, they function like capped instruments because the reeds do not touch the player's lips.

History shows us how these instruments have evolved over time. Double-reed instruments may have originated in the middle to late Neolithic period. This discovery is often attributed to observing wind blowing through a split rush. Early flutes were often made from natural tubular sections. People used grasses, reeds, bamboo, or hollowed-out tree branches. As technology changed, flutes were made of metals like tin, copper, or bronze. Modern concert flutes are often made of high-grade metal alloys containing nickel, silver, copper, or gold.

In modern music, woodwinds play essential roles in different groups. A typical orchestra includes flutes, oboes, clarinets, and bassoons. They may also use supplementary instruments like the piccolo or the contrabassoon. Concert bands use a much larger and more diverse selection. A concert band might include alto, tenor, and baritone saxophones. They may also use instruments like the bass clarinet or the cor anglais.

There are also unique instruments called free reed aerophones. These use small metal tongues arranged in rows within a frame. The air for these instruments comes from a player's breath or from bellows. Examples of this include the harmonica and the accordion. This shows the incredible diversity found within the woodwind family. From ancient bamboo tubes to modern metal saxophones, these instruments continue to shape music.
