How to holding cello bow
I personally feel that the cello’s power point should be on the upper arm, the upper arm with the forearm, and the forearm with the wrist. From the shoulders, they are very smooth and not bulged or recessed. If you can’t relax, it’s better not to practice. Practice first. To hold the bow, the right hand is much more important than the left hand. Relaxation practice is to practice with the right elbow with your left hand before playing the violin. It feels like the right arm is completely hanging down. There is no need for any strength. It is to hold the bow by holding a water cup. , The little finger and the index finger and the thumb are placed on the top and do not exert any force. In short, the smaller the strength of the hand, the better. It depends on the force of the bow on the strings to make the sound.
The point of contact between the finger and the bow
When practicing the piano, you need to emphasize the role of the right hand in pronunciation Where are the contact points between the fingers of the right hand and the bow
The right thumb is curved, the point of contact between the thumb and the bow should be on the corner of the bow, the nail is on the side of the bow.
2. Index finger
The bend of the first joint of the index finger, in general, it is in vertical contact with the bow rod. At the point of contact between the index finger and the bow to make the first and second joints rotate freely to obtain the required strength
3. Middle finger
Put half of the fingertip of your middle finger on the metal ring. The other half is placed on the bow hair, not only touching the metal ring and horsetail, but also to touch the bow. When contacting the bow shaft, the first joint should be solitary and attached to the bow shaft.
4. Ring finger
The ring finger should be placed straight on the bow hair box. And can touch its entire concave surface
5. Little finger
The little finger should be placed just above the small circle on the bow hair box
How to control the tone with a cello bow
1. Hold the bow and knead the strings correctly. In the performance method, the first thing that needs to be discussed is holding the bow. Holding the bow requires a standardized method. Similar to holding a pen, each tool needs to be used in a correct and standardized way. In our country, there are three ways to hold the bow of the cello. One of them is the German-style bow. It was used for a long time in Germany in the early days. Straight, this method is relatively old, suitable for playing classical music, the technical requirements are not high, and the tone is soft.
String rubbing is a series of movements of fingers on the strings. There are many methods of kneading, and the different methods are mainly divided into three categories, namely, fast kneading, medium kneading and slow kneading. Different kneading methods bring new differences to the timbre of music. In the process of kneading the strings, the magnitude of the finger movement, the force, the frequency, the area, etc., will affect the entire tone. For example, those with small amplitude, strong force, and slow frequency are more suitable for expressing dim and deep voices, while those with large amplitude, low force and fast frequency are suitable for expressing bright and rounded sounds. It can be seen from this that adding the way of stringing can make the sound fuller and show the player's interpretation of the sound. For example, in the second cello concerto, it strongly reflects the author's love for nature and the motherland. Each level has different emotional changes, and the performer can express it in different ways.
2. Choose the right bow method. Bowing is the way of pulling. Different people will have different understandings when choosing the corresponding bowing according to the content of the work, so the bowing methods used are also different. Although the bowing methods used in the performance of the works are different, you should try to choose the most suitable bowing method to express the content of the music more accurately.
The first is to divide the bow. The upper bow and the lower bow should be balanced as much as possible, and the bow should be close to the string. This must be ensured for each bow section. Generally, the faster part of the middle bow is used. Secondly, there is a continuous bow, where two or more sounds appear on a bow, and the volume of a continuous bow is lower than that of a sub-bow. Under normal circumstances, there should not be any pauses in Lian Gong, and should be smooth and lyrical. The bow is a self-used method developed from the split bow. It is divided into the split bow and the continuous bow. The continuous bow is a bow with multiple notes. It is more common in solo, but the method is more difficult to master. In the whole performance, the thumb The index fingers should use each other, from slow to fast, stopping cleanly. The last one is jumping the bow. The bow and chord of the cello can be separated. You can do the movement of tapping the ball first, and add the left and right sides. Pay attention to the fixed contact point, and the left and right should be matched with the height. The bow should be attached to the string and arm. The action should be small.
