1、吉他演奏姿势以及左右手练习（Guitar gestures and left and right hand exercises）Basic training for folk guitar and classical guitar and left and right handsPlaying posture1.1 holding a fiddleThe correct posture of holding a piano is very important. It ensures that the player can make the most rational use of the jo
2、ints and muscles needed by the body without causing fatigue very quickly.A highly appropriate chair and a guitar sole are required. The chair can not be handrails, the height of its feet landing, thighs parallel with the ground. Foot height is about 15 centimeters or so, general height is adjustable
3、.For the sake of performance, you should sit in the front of the chair. Move your left foot forward on the stool, and your right foot back slightly, and slightly to the right. The concave part of the guitar on the left thigh, right thigh close to the bottom of the guitar, piano and upper body slight

Check to see if all parts of the body are completely relaxed. The left hand naturally lifts up, ready to press the strings (fol
5、lowed by a special left hand technique). The contact between the right and left hand and the guitar is entirely for the sake of performance, and can not be used to assist the stability of the piano body, otherwise it will affect the flexibility of playing.1.2 left hand basic movementThere are 3 move
6、ments of the joints in the fingers: from the fingertips to the fingers, which are called the first, second, third joints in turn.The fingers of the left hand string are marked as follows:Index finger. OneMiddle finger. TwoRing finger. ThreeLittle finger. FourThe left hand thumb not according to the
7、string should be straight on the back and neck midline and middle finger position alignment. Left arm should be naturally drooping. Left hand each finger according to the string, the joint natural bent, first knuckle and fingerboard surface as vertical as possible, so that labor, according to the st
8、ring and accurate. According to the string position should be close to the silk (away from the product wire too far, will be false because of the string and noise, if pressed on the product wire, sound muffled, there will be noise). The left hand refers to the thumb of the string. The fingers touch
9、the string, and the nail hinders the string, so the left hand nail is clipped as far as possible. In the course of playing, except for the thumb, the belly and the fingers of the string finger, any part of the left hand can not touch the body.The left hand movement refers to the need for special emp
10、hasis.The neck of the guitar can be divided into four regions, with the left hand the first finger (index finger) as the number of character according to the number of order. (1) the original position, that is, the first place. The index finger is in the first case, with 1, 2, 3 and 4 fingers. The 4
11、 finger can be pushed to fourth. (2) the upper position, that is, the second to the ninth bit. The ninth point is called ninth Twelfth by one finger, and the 4 finger by two. (3) high position, that is, tenth to twelfth positions. (4) ultra high position, that is, more than thirteen bits. In the gui
12、tar playing, sometimes the left hand needs to do every finger, is responsible for the action of a character, and then requires flexibility and expansion of the left hand, very good. Sometimes the left hand needs to do a few finger movements on a character, when the angle between the left hand wrist
13、and arm increases, and the wrist and thumb move slightly toward the head.In the left hand on the neck movement can be divided into two types: horizontal movement and vertical movement. Lateral movement: the fingers do not change positions, but move between strings to strings. At this point, the wris
14、t is dominated by the arm (the angle between the arm and wrist is variable), and the fingers remain in the vertical direction of the string (plane). Longitudinal movement: change move. Before analyzing and moving, it is necessary to fully understand the two different concepts of shifting fingers and
15、 jumping fingers.The moving finger motion is the transport means in an alternating finger rather than at the same time, a jump motion is the process of transport means finger all Lixian, according to the string according to a note before fingers crossed fingers. The change of position is one of the
16、most important basic skills of stringed instruments, and the quality of the change is directly related to the continuity of play. The principle is: can shift refers to the action to complete the change you dont jump to jump to; must use action to complete the change, but also in the jump with the moving finger movements to refer to the former as prepared prior to t
