Background

Saxophone was invented by Belgian Adeft saxophone in 1840. The addov is a sharp instrument maker, and is good at playing black pipes and flute. He originally conceived of designing a bass instrument for orchestras that is more flexible than the opera fide number and can accommodate outdoor performance. He combines the mouthpiece of a bass clarinet with the body of an opercule and modifies it, naming by himself the new instrument, saxophone.

French composer biotez once written: "saxophone is mainly characterized by wonderful change of tone, deep and quiet, emotional feeling, and soft and worried, as if the echo in the echo, no other musical instrument can make the wonderful sound at the time when silence is silent.

However, the connection of the various components of the traditional saxophone is fixed by the tip screws, which is simple, but the threaded connection is not beautiful enough, which is not a defect for the saxophone which is known as aesthetic sense; in addition, as the saxophone works on the principle of continuous vibration and sound production, the tip screw can be loosened; in addition, the pretightening force among all bolts needs to be continuously adjusted during saxophone production, and the balance is achieved as much as possible, because for a tip musician, little change of click can influence the exhibition effect.
