Sax originally designed the saxophone in two versions: a soprano saxophone and a bass saxophone. He later added more sizes in between, creating a family of saxophones that ranged from the high-pitched soprano to the low-pitched bass.
The saxophone was initially met with skepticism from the musical community, but it quickly gained popularity. It was first used in military bands, but it soon found its way into classical music, jazz, and other genres. Today, the saxophone is one of the most popular instruments in the world, and it is played by musicians of all levels.
