The saxophone (also referred to as the sax) is a conical-bore transposing musical instrument that is a member of the woodwind family. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet. The saxophone was invented by the Belgian Adolphe Sax in 1841. He wanted to create an instrument that would both be the most powerful and vocal of the woodwinds and the most adaptive of the brass, which would fill the then vacant middle ground between the two sections. He patented the sax on June 28, 1846 in two groups of seven instruments each. Each series consisted of instruments of various sizes in alternating transposition. The series pitched in B♭ and E♭, designed for military bands, has proved extremely popular and most saxophones encountered today are from this series. A few saxophones remain from the less popular orchestral series pitched in C and F. These instruments never gained a foothold in the orchestral world. Although the C-melody was quite popular in the late 20's and early 30's as a parlor instrument it never gained a legitimate standing. Instruments keyed in F are rare.

While proving very popular in military band music, the saxophone is most commonly associated with popular music, big band music, blues, early rock and roll, ska and particularly jazz. There is also a substantial repertoire of concert music in the classical idiom for the members of the saxophone family. Saxophone players are called saxophonists.

Description

he saxophone consists of an approximately conical tube of thin metal, most commonly brass and sometimes plated with silver, gold, and nickel, flared at the tip to form a bell. At intervals along the tube are between 20 and 23 tone holes of varying size, including two very small 'speaker' holes to assist the playing of the upper register. These holes are covered by keys (also known as pad cups), containing soft leather pads, which are closed to produce an airtight seal; at rest some of the holes stand open and others are closed. The keys are controlled by buttons pressed by the fingers, while the right thumb sits under a thumb rest to help keep the saxophone balanced. The fingering for the saxophone is a combination of that of the oboe with the Boehm system, and is very similar to the flute or the upper register of the clarinet. Instruments that play to low A have a left thumb key for that note. The simplest design of saxophone is a straight conical tube, and the sopranino and sopranosaxophones are usually of this straight design. However, as the lower-pitched instruments would be unacceptably long if straight,for ergonomic reasons, the larger instruments usually incorporate a U-bend at, or slightly above, the third-lowest tone hole. As this would cause the bell of the instrument to point almost directly upward, the end of the instrument is either beveled or tilted slightly forward.

This U-shape has become an iconic feature of the saxophone family, to the extent that soprano and even sopranino saxes are sometimes made in the curved style, even though not strictly necessary. By contrast, tenors and even baritones have occasionally been made in the straight style. Most commonly, however, the alto and tenor saxophones incorporate a curved 'crook' above the highest tone hole but below the top speaker hole, tilting the mouthpiece through 90 degrees; the baritone, bass and contrabass extend the length of the bore by triple-folding this section.

Uses

The saxophone first gained popularity in the niche it was designed for: the military band. Although the instrument was studiously ignored in Germany, French and Belgian military bands took full advantage of the instrument that Sax had designed specifically for them. Most French and Belgian military bands incorporate at least a quartet of saxophones comprising at least the E♭ baritone, B♭tenor, E♭ alto and B♭ soprano. These four instruments have proved the most popular of all of Sax's creations, with the E♭ contrabass and B♭ bass usually considered impractically large and the E♭sopranino insufficiently powerful. British military bands tend to include at minimum two saxophonists on the alto and tenor.

The saxophone has more recently found a niche in both concert band and big band music, which often calls for the E♭ baritone, B♭ tenor and E♭ alto. The B♭ soprano is also occasionally utilised, in which case it will normally be played by the first alto saxophonist. The bass saxophone in B♭ is called for in band music (especially music by Percy Grainger) and big band orchestrations, especially music performed by the Stan Kenton "Mellophonium Orchestra". In the 1920s the bass saxophone was used often in classic jazz recordings, since at that time it was easier to record than a tuba or double bass. It is also used in the original score (and movie) of Leonard Bernstein'sWest Side Story. The saxophone has been more recently introduced into the symphony orchestra, where it has found increased popularity. In one or other size, the instrument has been found a useful accompaniment to genres as wide-ranging as opera, choral music and chamber pieces. Many musical scores include parts for the saxophone, usually either doubling another woodwind or brass instrument. In this way the sax serves as a middle point between woodwinds and brass, helping to blend the two sections
