• String mass. (thickness or gauge)
• String tension (how tightly it’s tuned)
• Distance (the length of the string actually vibrating)
• Stringed instruments produce sound when the strings vibrate. The faster the rate of vibration, the higher the pitch. There are three factors that affect the rate of vibration: string tension, mass, and distance.

Mass: At the same tension, a more massive (thicker gauge) string will vibrate fewer times per second, producing a lower note. That’s why we typically see thick strings used for bass strings. With the objective of keeping the overall string tension balanced, heavy strings are used for the lower notes and thinner strings for high notes.

Tension: Once the string gauge is selected, we tune the precise pitch by tightening or loosening the string tension. Higher tension will produce a higher note. This is usually done by turning a tuning peg.

Length: At the same tension, a shorter vibrating length will produce a higher note. Once a string gauge is selected and the tension (tuning) is set, the pitch of each individual string can be raised by shortening the distance of it’s vibrating length. Typically this is done by pressing the strings (fretting), but can also be done with a slide.
