The saxophone (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.
