History
This magnificent instrument was invented by Adolphe Sax from Belgium. Akin to his father, Charles Joseph Sax, he was an instrument maker. The saxhorn, his first successful creation, was made public some time after he transferred to France. Adolphe Sax completed several developments to the bass clarinet prior to focusing on the saxophone.
The saxophone was created around 1846. Sax's primary key work was very basic which made wide intervals quite hard to finger. To make playing less difficult, many developers and instrument makers added alternate fingerings and more keys. One of the most substantial advancements in its key work was that both tone holes can be controlled by the left thumb using one octave key. This configuration is now common to all modern saxophones.
