How do musicians bring instruments into tune?
Two instruments can play what is meant to be the same note but produce slightly different pitches. Musicians use a shared reference, such as a tuning note, to bring those pitches into agreement.

On a guitar, turning a tuning peg changes the tension in a string. With its length and mass otherwise similar, a tighter string vibrates faster and makes a higher pitch. A looser string vibrates more slowly and makes a lower pitch.
A musician can compare the string with a reference by listening or using a tuner. A tuner measures the repeating sound and shows whether its pitch is above or below the chosen note. Loudness is a separate feature: playing more loudly is not the same adjustment.
After one note is set, other notes must fit the instrument’s tuning system. Pianos, flutes and drums have different structures, so their adjustments differ. Tuning is a connection between the sound people want and the physical parts that make it.
About this explanation
Starting knowledge: Distinguish a higher pitch from a louder sound and recognize repeating vibrations.
