The saxophone was invented by Adolphe Sax, who wanted to create an instrument that combined the projection of a brass instrument with the agility of a woodwind. Although it is made of brass, it is classified as a woodwind because it uses a single reed to produce sound. Adolphe Sax originally intended it for use in symphony orchestras, but classical composers were slow to adopt it. Instead, it became a staple of military bands and, later, the defining voice of Jazz. There are eight members of the saxophone family, but the most common are the Soprano, Alto, Tenor, and Baritone.
