1. Species:
The rated notation of score materials such as guitar music collections and textbooks is single-line pure staves with multiple voices (take solo notation as an example). This standard was established in the Segovia period and used in the 21st century, and has been circulated in the classical guitar industry. In the detailed notation used in the textbook, in addition to the notes, specific fingering tips can also be marked, marking the finger for pressing/plucking, and the fret/string position of the desired tone.
2. Clef:
Classical guitar belongs to the treble clef notation of mid-bass instruments, and the custom "central C" is one octave lower than the central C of the piano.
