Why does classical guitar have to use staff notation?

In fact, people who read music notation may not necessarily understand music theory. The relative music notation expresses the sound and the six-line music notation. However, the piano staff notation expresses both the shape and the sound. Therefore, it is good to read the music notation on the piano, but the guitar is very free. You only need to be musical. By the way, it doesn't matter where you press it. Most people who talk about classical music are obsessed with playing the piano music. The musical notation is specially produced for the piano and is not suitable for the guitar. I am firmly against the use of staff notation for guitars, no matter classical, or even more so for folk electric guitars, although I have no problem reading staff notation. Many people who read staffs do not understand harmony and can only play mechanically according to the music. It is difficult to practice and forget them quickly. Nothing will happen until old age. "Throw away the staff, learn some harmony, and you can fly freely," a call from an experienced person. In fact, harmony, counterpoint, etc. are specialized subjects and have no direct relationship with whether you can read music or not. If you want to study subjects such as harmony and acoustics, then those who can read music notation will definitely have certain advantages over those who can only read six-line music (the so-called only reading music notation means that they can only recognize positions according to the music). It seems that there is no music theory that can be explained using six-line notation, although I don’t understand music theory either. If you can still play wonderful music by relying on six-line notation, I don’t think anyone will laugh at you because you don’t know five-line notation. Many of your songs are written with five-line notation; many introductory etudes for daily practice are written with five-line notation; at present, These tunes have not been translated into tablature or are difficult to find, so if you want to play these tunes, you have to learn tablature. It can be said that this is a daunting task, unless you don't like these tunes. Staff notation is not difficult and can be learned in a few hours, but the familiarization process takes a relatively long time. In fact, the same is true for six-line notation. To achieve immediate correspondence with the fingerboard, it also requires a long time of practice. As far as the guitar is concerned, six-line notation has many advantages, but we have to admit that many six-line notation is full of errors. The fault is not the six-line notation itself, but the irresponsible music maker. Haha, someone who doesn’t even want to learn music notation can still have the patience and the right approach to learn harmony and music? In fact, the person who invented the staff score was very, very great, because in the past there was no standard for 'reading' and 'writing' music. Every musician was different, so how could others understand it? Unification is good, just like Qin Shihuang's currency text. It may be difficult for some people to start over, but at least everyone will not have conflicts in the future. I can responsibly assert: There are basically no geniuses who play guitar in China. Therefore, if you don't want to be a self-righteous idiot, I suggest you put aside your "personality" as an artist, be honest first, and learn all the basics closely related to music, including staff. All in-depth, formal stuff that involves a lifelong study of harmony, theory, composition, and performance is all done in five-line notation. Unless you are a once-in-a-century genius who can completely overturn this musical language model and system. 1. It’s not necessary. 2. It is easier to sight-sing five-line notation than six-line notation. 3. Music notation is easier to preserve than fingering notation. Guqin is a typical negative example.
