Description

Clarinet barrel in crystal glass {CLARINET BARREL MADE OF CRYSTAL GLASS}

   The present invention relates to a barrel of a clarinet, and more particularly to a clarinet wherein the material of the barrel is crystal glass.

   Barrels that form part of a conventional clarinet are known to determine about 70% of the tones produced by the clarinet. The material of these barrels is mainly African cedar. Although metal materials are used but are rarely used in clarinet masterpieces, the wooden barrels used above should be used to play clarinet songs of good quality.

   However, the barrel made of wood is easily deformed during drying during the manufacturing process, and the saliva of the player is continuously adsorbed during long-term use, causing severe changes in physical properties, and at the same time, impeding the communication of the wind, and thus could not produce an accurate tone.

   In addition, because the wood material absorbs moisture well, it is easy to be deteriorated and difficult to clean and manage.
