How does Tenor Sax make sound?
We, as saxophone players, provide a flow of air with a bamboo reed attached to the mouthpiece through the saxophone, and sound is produced by the air flow. Once the air in the saxophone is vibrating, some of the energy is radiated as sound out of the bell and any open holes. At the same time, most of the energy is lost as a sort of friction with the inner saxophone wall.
What material is it made out of?
The bodies were and are made of brass, often lacquer-coated. The keywork is made of plated steel, with interior mechanism rods of steel. Saxophones’ mouthpieces are usually made out of hard plastic compound, and lastly, the reeds are definitely made out of bamboo.
What family members does it have?
The saxophone family includes sopranino (E Flat) (F), soprano (B Flat) (C), alto (E Flat) (F), and baritone saxophones (E Flat), Bass (B Flat) (C), Contrabass (E Flat) (F). Tenor sax is considered as a medium-sized saxophone compare to the rest of its family.
