Saxaphone

The saxaphone (also referred to simply as sax) is a conical-bored transposing musical instrument considered a member of the woodwind family. Saxophones are usually made of brass and are played with a single-reed mouthpiece similar to that of the clarinet. The saxophone was invented by Adolphe Sax in 1841. He wanted to create an instrument that would both be the loudest of the woodwinds and the most versatile of the brass, and would fill the then vacant middle ground between the two sections. He patented the sax in 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.

While proving very popular in its intended niche of 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.

The saxophone was developed in the 1840s by Adolphe Sax, a Belgian-born instrument-maker, flautist and clarinetist working in Paris. While still working at his father's instrument shop in Brussels, Sax began developing an instrument which had the projection of a brass instrument with the agility of a woodwind. Another priority was to create an instrument which would overblow at the octave, unlike the clarinet, which rises in pitch by a twelfth when overblown; an instrument which overblew at the octave would have identical fingering for both registers.

The saxophone consists of an approximately conical tube of thin metal, most commonly brass, 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 can be controlled by a number of buttons by the left and right fingers, while the right thumb sits under a thumb rest which helps 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. On the larger instruments, the leverage required to play the very lowest notes (which are customarily played with the left and right little fingers) is great enough that additional keywork is introduced to enable these to be played with the thumbs.

The simplest design of saxophone is a straight conical tube, and the sopranino and soprano saxophones 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 upwards, the end of the instrument is either beveled or tilted slightly forwards. 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 this is 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 mainly by double-folding this section.

Most saxophones, both past and present, are made from brass. Despite this, they are categorized as woodwind instruments rather than brass because the sound waves are produced by an oscillating reed, not the player's lips against a mouthpiece as in a brass instrument, and because different pitches are produced by opening and closing keys. Brass is used to make the body of the instrument; the pad cups; the rods that connect the pads to the keys; the keys themselves and the posts that hold the rods and keys in place. The screw pins that connect the rods to the posts, and the needle springs and leaf springs that cause the keys to return to their rest position after being released, are generally made of blued or stainless steel. Since 1920, most saxophones have 'key touches' (smooth decorative pieces placed where the fingers touch the instrument) made from either plastic or mother of pearl.

The saxophone uses a single-reed mouthpiece similar to that of the clarinet. Most saxophonists use reeds made from Arundo donax cane, but since the 20th century some have also been made of fiberglass. Fiberglass reeds are more durable, but are generally considered to produce an inferior tone. The saxophone mouthpiece is larger than that of the clarinet, has a wider inner chamber, and lacks the cork-covered tenon of a clarinet mouthpiece because the saxophone neck inserts into the mouthpiece whereas the clarinet mouthpiece piece is inserted into the barrel. The most important difference between a saxophone embouchure and a clarinet embouchure is that the saxophone mouthpiece should enter the mouth at a much lower or flatter angle than the clarinet. Mouthpieces come in a wide variety of materials, including vulcanized rubber (sometimes called rod rubber or ebonite), plastic, and metals such as bronze or surgical steel. Less common materials that have been used include wood, glass, crystal, porcelain, and even bone. According to Larry Teal, the mouthpiece material has little, if any, effect on the sound, and the physical dimensions give a mouthpiece its tone colour, however this view is controversial. Mouthpieces with a concave ("excavated") chamber are more true to Adolphe Sax's original design; these provide a softer or less piercing tone, and are favored by some saxophonists, including students of Sigurd Raschèr, for classical playing. Conversely, mouthpieces with a smaller chamber or lower clearance above the reed, called high baffle, produce a brighter sound with maximum projection and are favored by many jazz and funk players. Most skilled saxophonists settle on a mouthpiece somewhere between these extremes regardless of their primary idiom and most that play both jazz and classical music have different equipment for each.

Like clarinets, saxophones use a single reed. Saxophone reeds are proportioned slightly differently to clarinet reeds, being wider for the same length. Each size of saxophone (alto, tenor, etc.) uses a different size of reed. Reeds are commercially available in a vast array of brands, styles, and strengths. Each player experiments with reeds of different strength (hardnesses) and material to find which strength and cut suits his or her mouthpiece, embouchure tendencies and playing style.

The saxophone was originally patented as a group of 14 instruments in two families. The orchestral family consisted of instruments in the keys of C and F, and the military band family in E♭ and B♭. Each family consisted of sopranino, soprano, alto, tenor, baritone, bass and contrabass instruments, alternating in transposition. While all seven members of the military band family are still relatively common, the orchestral group was less successful; Adolphe Sax's personal rivalry with influential German composer Wilhelm Wieprecht may have been partially responsible for the complete failure of the saxophone in orchestral music. Only the orchestral tenor and soprano saxes, both pitched in C and therefore able to easily play music written for strings or voice, attained any popularity; the tenor was popularized by players such as Rudy Wiedoeft and Frankie Trumbauer, but did not secure a permanent place in either jazz or classical music. In the early 20th century, the orchestral soprano was marketed to those who wished to perform oboe parts in military band, vaudeville arrangements, or church hymnals. None have been produced since the late 1920s. The orchestral alto, produced by the American firm Conn during the period 1928–1929, is now extremely rare; most remaining examples are in the possession of serious instrument collectors. Adolphe Sax made a few F baritone prototypes, but no serious F baritones were manufactured. There are no known remaining specimens of the bass saxophone in C, the first saxophone constructed and exhibited by Sax in the early 1840s, or the sopranino in F, despite Ravel's scoring for the instrument in Bolero. The only known F alto made by Sax himself known to exist is owned by retired Canadian classical saxophonist Paul Brodie.
