It can be controlled by many things, but here are at least three:
Length of the vocal cords.
Thickness of the vocal cords.
And stress on the vocal cords.
That of course, it is the human body.
If your talking about, say, a guitar amp, it's controlled by the little nob that says 'pitch' on it.

Can extraneous variables be controlled?
no the variables cant be controlled.
What does controlled mean?
Radio controlled refers to something that is controlled by remote means via radio frequency, such as radio controlled cars or planes. It is slightly different than remote controlled items which usually have a wire connection.
How do you know if something is controlled in science?
if the experement can be repeated and the same results made then the experement is controlled if not the experement is not controlled
In a research study if one variable is changed to see how it affects behavior the study is most likely a?
experiment
What are 5 things the wright brothers did?
Invented the first controlled airplane Flew the first controlled airplane Tested the first controlled airplane Created the first controlled airplane and.... the last is for another Wiki-Goer.
How pitch controlled in the human voice?
Pitch in the human voice is controlled by the tension and length of the vocal folds in the larynx. When the vocal folds are stretched tightly, the pitch produced is higher, and when they are looser and thicker, the pitch is lower. The rate and force of air passing through the vocal folds also contribute to controlling pitch.
How does sound get controlled?
Sound can be controlled by adjusting factors like volume, pitch, and tone. Volume is controlled by regulating the amplitude of sound waves, while pitch is altered by changing the frequency. Tone can be adjusted by manipulating the harmonics present in the sound wave.
What are the 3 controlled movements an airplane fly what are they?
Pitch, Roll and Yaw
When playing a trumpet how do you change the loudness and pitch?
Volume is controlled by air flow, and pitch is changed with the valves and lip configuration.
How many controls do airplanes have?
Most general aviation airplanes have pitch, yaw and bank controls. The pitch is controlled by the elevators, the yaw is controlled by the rudder pedals, and the bank is controlled by the alerons. Also there is what is called a trim tab which are intergrated in the elevator and rudder to take pressure off the control wheel or Yoke, or stick as it is called.
What has the ability to vary the pitch of the voice results from varying?
Varying the tension and length of the vocal cords can change the pitch of the voice. Tightening the vocal cords raises the pitch, while relaxing them lowers the pitch. The pitch of the voice is controlled by muscles in the larynx.
How does a drum make its pitch?
The tympanic membrane sends vibrations and waves when struck, which reflect around in the drum.I think the pitch is controlled by the tightness of the tympanic membrane.
How do your vocal cords produce different pitches?
The pitch of the sounds produced by the vocal cords is controlled by the tension and length of the vocal cords. When the tension and length increase, the pitch becomes higher, and when they decrease, the pitch becomes lower. This adjustment is made by the muscles in the larynx.
How does a drum create pitch?
It has to do with the tightness with which the head is stretched over the shell. The tighter the drum head, the higher the pitch, and vice versa. If the drum has a head on the top and bottom of the shell, the pitch is more controlled from the top head whereas resonance is more effected by the bottom head.
How sounds can be controlled?
Sounds can be controlled through factors such as volume, pitch, duration, and quality. Using tools like soundproofing materials, equalizers, and volume controls can also help manage and adjust sound levels. Additionally, sound can be controlled through techniques like sound absorption and reflection to manipulate how it travels and interacts with the environment.
How does a pilot control roll pitch and yaw?
In classic aircraft controls, the airplane's rudder controls yaw, the elevators control pitch and the ailerons control roll. The control handle controls rudders and elevators while ailerons are controlled by foot pedals.
How does a pianola change its pitchand volume?
A pianola changes pitch by varying the speed at which the paper music roll is fed through the mechanism. Faster speed increases pitch, slower speed decreases pitch. Volume is controlled by adjusting the amount of air flowing through the instrument, usually done through a foot-operated bellows pedal system.
