The Structure of the Saxophone
Learn the names of the parts
Four large sections
The saxophone consists of four fundamental parts: the neck, the body, the U-shaped bow, and the round, flared bell. Along the length of the instrument, there are 25 tone holes.
Saxophone components
A staggering 600 parts!
Though there are 25 tone holes, a person has far fewer fingers, so keys and levers are provided to enable the player to close distant holes simultaneously with others.
The round tone-hole covers are called pads. The largest pad on an alto saxophone is five centimeters in diameter. Of course, this large pad covers an equally large tone hole.

The pads are made from circles of felt covered with sheep leather.
Because a number of parts work together for a single function, a single saxophone comprises about 600 parts.
