When tuba valves are pressed, the air column is shortened, resulting in lower notes. group of answer choices true false

False

Explanation:

Tuba is the largest instrument in this family and that is why it should be played on the legs The sound is produced thanks to the vibration of the lips on the mouthpiece. To make different notes it is necessary to operate the piston valves or the cylinders it has (fingers from 3 to 6) with your fingers and change the air pressure (blow faster and with more pressure to produce higher notes). The sound comes out of the bell. Tubas, like all wind-metal instruments, have an accessory called a mute, which is placed inside the hood in order to reduce the volume and achieve other sound effects.
