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.
Adolphe Sax
After leaving the Royal Conservatory of Brussels, Sax began to experiment with new instrument designs, while his parents continued to make conventional instruments to bring in money. Adolphe's first important invention was an improvement of the bass clarinet design, which he patented at the age of 24. Sax relocated permanently to Paris in 1842 and began working on a new set of instruments. Hector Berlioz was so enamoured of them that he arranged in February 1844 for one of his pieces to be played entirely on Sax's new instruments. These were valved bugles, and although he had not invented the instrument itself, his examples were much more successful than those of his rivals and became known as saxhorns. They came in seven different sizes, and paved the way for the creation of the flugelhorn. Today, saxhorns are sometimes used in concert bands, marching bands and, orchestras. The saxhorn also laid the groundwork for the modern euphonium.
