The manufacture of saxophone is divided into parts and pipes: (1) The parts include key posts, pressure plates and keys, which need to be finely polished and painted. A standard saxophone has twenty-five sound holes, and related components, such as keys, key posts, leather pads, elastic steel needles, pressure plates, corks, etc. , are dazzling and time-consuming. (2) After repeated welding, hammering, gold plating, polishing and other processes. Every detail of the trumpet, mouthpiece, barrel and elbow of the tube body should be beautified, that is, the surface treatment should make the saxophone look as shiny as a layer of gold. It takes more than a month to make a saxophone, and the pipe model, which is very important for pitch, is an extremely important basic tool in making because of its tonic hole. A slight mistake, saxophone can't play melodious melody. Secondly, the material of the leather cushion is good enough, which is closely related to the sound hole. The most important material of the elastic steel needle is good or bad, which are all factors that affect the value of a saxophone.
