“The saxophone is a member of the woodwind family. It was developed in 1846 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. 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. While proving very popular in military band music, the saxophone is most commonly associated with jazz and classical music. There is substantial repertoire of concert music in the classical idiom for the members of the saxophone family. Saxophone players are called saxophonists.
Another priority was to invent 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.
Sax’s patent expired in 1866; thereafter numerous saxophonists and instrument manufacturers implemented their own improvements to the design and keywork. The first substantial modification was by a French manufacturer who extended the bell slightly and added an extra key to extend the range downwards by one semitone to B♭. It is suspected that Sax himself may have attempted this modification. This extension was adopted into almost all modern designs.”
