The saxophone (also referred to simply as sax) is a conical-bored transposing musical instrument which is 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.
