How to practice the flexibility and independence of the left hand in guitar introduction? Shenzhen Baoan learns guitar.

The flexibility and independence of the left hand are mainly in the last three fingers (middle finger, ring finger and little finger):

(1) Left-hand middle finger pressing: Press a certain product of the sixth string (the thickest string) of the guitar with the middle finger of the left hand, and play hard with the thumb of the right hand to keep the pronunciation. Then, the index finger and ring finger of the left hand pluck a string (the thinnest string) one by one. It can be played in triple time. The first beat is to press 6 strings with the middle finger of the left hand and play with the right hand. This note should be kept in three beats. The second beat is made by bending the index finger of the left hand; The third beat is the left ring finger. Be sure to practice slowly, that is, play slow three. Then, practice in each position. This means that when the middle finger is pressed in practice, the adjacent index finger and ring finger can be lifted in the opposite direction.

Please note the following two points:

1, press the finger, each joint should have a certain radian, and each joint should not be too straight or too curved. It is forbidden to have an unnatural shape in which one joint of the same finger is straight and the other joint is bent. It is not required to press strings with fingertips, but between fingertips. The pressed finger should be parallel to the piano.

2. Fingertips (nails) are required to be perpendicular to the fingerboard and strings of the piano when plucking fingers with the left hand-this is the difficulty-the big joints of plucking fingers with the left hand are almost negatively curved (i.e. curved in the direction of the back of the hand), while the big joints of pressing fingers with the left hand are positively curved (i.e. curved in the direction of the palm)-the adjacent finger nerves are completely stressed in the opposite direction, prompting nerve separation.

(2) Ring finger pressing of the left hand: same as above, except that the middle finger on it is replaced by the ring finger, while the index finger is replaced by the middle finger and the ring finger is replaced by the little finger. The requirements are exactly the same. Obviously, this difficulty has increased, and many people will feel the great involvement of neighboring fingers. At the beginning of training, when the left finger plucks the string, the pressed finger can use a little thrust to offset the involvement.

(3) Left little finger pressing: Same as above, except that only one ring finger is adjacent to the little finger, and generally the little finger is shorter. You don't have to press the sixth string, but the fifth string, and then dial a string with your ring finger. The requirements are the same as above. It is difficult to maintain the corresponding radian of the middle joint or facet joint of the little finger, so pay more attention.

I wish you success!
