What are the meanings of various note symbols on the guitar? Please elaborate.

Six-string notation is to draw six parallel horizontal lines, corresponding to the six strings of a guitar, to represent the position and movement (fingering) played by both hands, rather than the recorded sound level. But it is very convenient to use it in combination with notation or staff, which can indicate both pitch and fingering.

The commonly used guitar playing methods (solo, decomposed accompaniment, diffused rhythm) have the following recording methods:

Solo (Melody) notation: Write Arabic numerals on six lines.

Accompaniment score with broken strings: draw an "X" on the six-line score. At this time, there are often fingering charts or marks above the hexagram of left-handed chords. Then you press the chord with your left hand, and "X" means playing the chord with your right finger.

Chord-sweeping rhythm notation: draw symbols such as ↑ and ↑ on six lines. At this time, there is often a hint of left-handed fingering above the staff. Sometimes, the above symbols will appear in the same six-line score.
