 Have you thought about where the guitar sounds come from . The sounds of notes or chords come from holding the strings down against the neck of the guitar with the left hand. The frets on the neck are raised embedded metal thin bars. The guitar strings when picked or strummed vibrate until held down on the frets. Classical guitars are the most popular among the different types. The strings of the classical guitars are made from nylon and they are commonly used to play classical music.

 Steel guitars often don't have raised frets which would interfere with the gliding pitch sound that a steel guitar makes. The pitches on a steel guitar are changed by the sliding of a steel bar up and down the strings, hence the name steel guitar.

The tuning of the bass guitar is the same as for the bottom four strings of a electric guitar but down one octave, and the strings are thus heavier and thicker.
