Just like graffiti is a free art and painting is an academic art, folk guitars allow various free and diverse ways of playing, so players can give full play to their understanding of music, while classical guitars must follow the rules and play completely according to the written music scores, and each stroke and style has been trained for a long time. Many music scores of classical guitars have been circulated for decades.

Therefore, from this perspective, folk guitar is graffiti, because the form of expression is very free, making people not stick to the form. Classical guitar is painting, which refers to the academic way of playing.

I wonder if you agree with this?
