The composer's work is presented to people in the form of musical scores. Only through the second creation of the musical instrument in the player's hand can the beautiful and beautiful music be conveyed to the audience.

In Liuqin teaching, how to rapidly improve students' technical skills is an important issue that needs to be paid enough attention. There are many technical skills in Liuqin, but according to the author's opinion, in the teaching of Liuqin, the solution of the following problems is particularly important.

Preserve Finger Sustain Technology
This problem is a peculiar technical problem of liuqin and fret instruments. In the performance of liuqin, as soon as the pressing finger leaves the fret, the reverberation will be cut off immediately. This pronunciation characteristic of liuqin determines the importance of its sustain technique. Therefore, in the process of liuqin playing, it is necessary to raise the fingers as late as possible, or not to lift the fingers (retain the fingers), and fully release the residual sound to ensure the accuracy and coherence of the note timing and ensure the smoothness of the music. The author calls this "" Keep finger sustain technique". Reverberation is the life and charm of a plucked instrument. Liuqin is a high-pitched instrument, and its reverberation is short, so how to prolong its pronunciation as long as possible is particularly important. Facts have shown that "retain finger sustain technique" is the most effective means to solve the problem of residual sound.

handlebar technology

In the process of playing, general players often have problems such as traces of changing the handle, unsmooth melody, rushing time, dragging the rhythm, inaccurate and unrealistic frets, etc., resulting in deflation, wrong tone, and even sound leakage. problem. The above problems mainly exist in fast performances, such as continuous sixteenth notes, thirty-second notes or tuplets above the fifth, and in fast passages and large jumps of melody.
To solve this problem, we must first clarify a concept: the function of the left thumb is not mainly to support the piano. On a piano equipped with a bracket, the bracket is the main point of support for the balance of the piano, and the thumb is only lightly resting on the neck of the piano to play a supporting role. Although the Liuqin holds the qin with a slight inclination and the center of gravity is to the left, the thumb is basically freed by finding the balance point of the support.

Secondly, the left hand should maintain the most natural and relaxed half-clawed fist shape. The thumb should not be stiff or sunken. The big jump should change the forearm to mainly drive the wrist, and the small jump should change the wrist to link the forearm. Changing the handle downwards will be more labor-saving due to the inertial movement of the principle of free fall (the effect of the earth's gravity); changing the handle upwards relatively has a force to lift the arm and wrist, and requires the fingers to move quickly and prepare in advance, but the premise is not to affect Change the quality of the previous tone. The last tone before changing the handle and the first tone after changing the handle is the key. The quality of these two sounds is good, and the changing of the handle is basically successful.

Unclear sound problem

It is a common problem that the liuqin and other plucked instruments with frets have unclear notes when playing. The main reasons are as follows:

1. The intensity is uneven, and the strings are both virtual and real.

To solve this problem, first of all, it is necessary to strengthen the practice of balanced strength of the four fingers and the finger strength of the large joints of the left hand to enhance the strength of the fingers.

2. The time difference between the two hands is not well mastered.

The two-hand coordination of a plucked instrument is somewhat more difficult than that of a bowed string instrument, because it is docked with the left hand in a "point" state of the right hand (the right hand of a bowed string instrument is docked in a "line" shape with the left hand). In the picking technique, if the left hand presses the string later than the right hand, the note must be 'dead' (flattened). In long rounds or sixteenth notes, these notes are still "dead" if the left hand is pressed in between the right hand and the quick pick. This requires the left hand to press the string earlier than the right hand to play the string a hundredth (or even a thousandth) of a second.

3. The duration of pressing the strings on the frets is too short, and the reverberation is insufficient.

The pitch of the liuqin is determined by changing the length of the strings by the accessories. The time when the left finger presses the strings on the frets, the virtual and the real are the important factors and reasons that affect the clarity of the notes, and the reverberation time of the notes is mainly controlled by the left finger. It is required to keep the finger on the fret as long as possible to fully release the reverberation and keep the notes clear and smooth.

4. Fingers or picks stay on the strings for too long.

The slow action of fingers pressing the strings or lifting the fingers, the rate at which the right-hand pick touches the strings is too slow, and the fingers or picks stay on the strings for too long, which hinders the vibration of the strings and also causes unclear notes. one. This requires the action of the fingers of the left hand and the rate at which the right-hand pick passes over the strings to be faster. Let the strings vibrate fully for a clear sound.
