Keeping the wrist in a straight line with the hand is one of the most important requirements for standard piano playing.
The palms and forearms are in a straight line that stretches naturally, and the wrists are neither concave nor protruding. Turn the palm slightly inward, the thumb and the index finger and the middle finger are facing each other, gently clamp the violin with the thumb and the base of the index finger, and pay attention to the muscles at the base of the thumb must be relaxed. The depth of the thumb position should be determined according to the specific situation of each person's thumb, but no matter how long or short, the tiger's mouth must not be attached to the neck of the piano.
The wrist is obviously bent, which will directly lead to the inability to stretch the fingers, it is difficult to press the pitch, not to mention other various skills such as flexibly changing the position.
Notes for pressing strings:
If the violin wants to play perfect music, in addition to the skillful and accurate control of the bow with the right hand, it must also rely on the fingers of the left hand to instantly press the strings on the fingerboard. The faster the speed, the clearer and more natural the sound quality will be, but in In the process of pressing the strings, the strength must also be handled well, so that the fingers cannot be too stiff.
In order to make the movement of the left hand correct, flexible, agile, powerful and natural and comfortable, and the right hand to move the bow easily and freely, the correct posture of holding the piano must be maintained. The violin should be flat (usually the strings are flat, but it can be higher or lower according to the actual needs of the performance), the surface of the violin should be slightly inclined to the right, and the direction of the violin should be slightly left. The left angle of holding the piano varies from person to person.
The fingers of the left hand are naturally curved semi-circular hands when pressing the strings, and the fingers should also be semi-circular when lifted from the strings. The actions of finger pressing and lifting mainly depend on the base of the finger joints, followed by the adjustment of the small joints according to the size of their intervals, and the speed of the ups and downs of the fingers is determined by the length of the note time, the speed of the music, and the mood (but The exception is to practice finger agility and strength).
The second joint of the thumb is slightly bent, the center of the thumb is facing the neck, and the second joints of the other four fingers should be slightly bent, so that each finger is in an arc, so that the fullest part of the abdomen of each finger can be obtained. touch the strings.
The thumb and index finger are in a V shape, and there is a certain space between the tiger's mouth and the neck; in the wrong demonstration on the right, there is no certain space between the tiger's mouth and the neck, and the thumb exceeds the fingerboard too much, which will cause the piano to be held too tightly, and Tension in the thumb leads to various problems such as inflexibility of the fingers of the left hand.
The index finger is called 1, the middle finger is called 2, the ring finger is called 3, and the little finger is called 4. Put them on the tape of the four notes of Fa, So and La Si in turn. When sticking the tape, you should ask an experienced person to assist, or use a sound effector, adjust the standard sound, and then stick the tape on the cardboard. If your finger goes beyond the tape, the sound will be high, otherwise, the sound will be low .
The little finger is hidden under the fingerboard, or the finger points to the sky. If the finger needs to be used, the pronunciation will not be timely, and the extra movement will cause the song to be unsmooth. (Wrong demonstration, please don't learn it!)
