Adolphe Sax
Antoine-Joseph Sax was born on 6 November 1814, in Dinant, in what is now Belgium, to Charles-Joseph Sax and his wife. While his given name was Antoine-Joseph, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made several changes to the design of the French horn. Adolphe began to make his own instruments at an early age, entering two of his flutes and a clarinet into a competition at the age of 15. He subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels.
Baritone saxophone
The baritone saxophone was created in 1846 by the Belgian instrument maker Adolphe Sax as one of a family of 14 instruments created to be a tonal link between the woodwinds and brasses, which Sax believed to be lacking. The family was divided into two groups of seven saxophones each from the soprano to the contrabass. The family consisting of saxophones ranged in the keys of B and E were more successful because of their popularity in military bands. The bari sax, pitched in E, is the fifth member of this family.
