What are the guitar plucking methods in classical guitar teaching?

Teacher Xiong Guitar tells you: Two playing methods of classical guitar.

First, nail pie, there are full nails and half nails.

The whole nail is pulled out directly with the nail, and the nail stays longer. Touch the half nails with your fingers, and then pull them out with your nails. The nails are shorter.

Second, finger cakes, playing without nails.

The two factions have their own strengths, which should be determined according to their own conditions and habits. But at present, more people play the piano with their nails. Don't leave your nails too long. Generally, it is enough to show your fingers 1-2 mm, otherwise it will affect the performance. Don't trim your nails, it's best to keep them flat and round. The left side of the thumb nail needs to be trimmed into a slope to facilitate coding. If the nail is soft and thin, it should be shortened appropriately. Applying several layers of colorless nail polish on the nail surface can increase the hardness of the nail and ensure the strength and volume of plucking.
