makes it move faster meaning a more high pitched sound
The sound is produced by the vibration of the string.
The vibration is changed by either reducing the length of the string (holding it down on a fret) or changing the tension of the string.
Moving your finger along the string will alter the length and the pitch of the sound produced.
Varying the length of a string changes its vibration frequency. A shorter string vibrates at a higher frequency while a longer string vibrates at a lower frequency. This relationship is described by the formula: frequency is inversely proportional to the length of the string.
There are some complex physics behind string vibrations. Essentially, the looser the string, the less nodes, or points where the sound waves go from crest to trough. This of course affects the frequency, or rate at which the string vibrates. So when the string is tightened, more nodes are created, and the frequency increases, increasing the pitch.
You can change the vibration speed of a string or rubber band by adjusting the tension in the material or by changing its mass. Increasing tension or reducing mass typically increases the vibration speed, while decreasing tension or increasing mass typically decreases the vibration speed.
The longer the string - the slower the vibration (and lower the note produced). If you shorten the string - it vibrates faster, producing a higher-pitched note,
A violin produces sound by the vibration of the bow on the string, or the vibration when you pluck a string.
higher. By tightening the string, you increase the tension, causing the string to vibrate faster and produce a higher pitch sound.
To change the frequency of a guitar string, you would adjust the tension on the string by turning the tuning pegs. Tightening the string increases the frequency, while loosening it decreases the frequency. Tune the string to the desired pitch using a guitar tuner or by ear.
