How a guitar works
Pitch
Pitch of a vibrating object depends on 3 things.
When the string get thicker/bigger, the vibration of the string moves more slowly. On the steel guitars the strings get bigger and thicker from high to low. On the classical guiar, the size change is difficult by a change in density. The low density nylon strings gets larger from E to B to G. The higher density wire-wound nylon strings get larger from D to A to E.
The frequency can be changed by changing the tightness of the string using a tuning pen. when you hear a higher pitch that means that the strings are tighter.
The freguenency also depends on the length of the string that is able to vibrate.
Guitar strings are not big enough to move big enough amounts of air to make a sound that humans can easily hear. An acustic guitar is normally made of light, springy wood that is about 2.5 mm thick. The body of an acustic guitar is used to make the sound be amplified.
"Sound is created when material vibrations causes changes in the air pressure and create pressure waves."
