Hitting practice is actually the foundation of vibrato fingering. The single tone is also known as "single tone". The index finger single tone is to play the upper tone of the empty string to achieve the purpose of decorating the empty string. When practicing the sound, the left hand should be relaxed, and the ups and downs of the index finger should be flexible. The key point is to practice the ability to swing the finger joints, such as the height, strength and speed of the fingers.
Here is an example of an index finger tap practice:
index finger practice
The picture above is the practice of index finger tapping. Continuous beating is a kind of vibrato action, as shown in the picture.
The index finger, like the little finger, is weak when hitting the sound. Only with more practice can the elasticity of the index finger and the granularity of the sound be enhanced.
On the basis of slow practice, you can gradually increase the speed and frequency of the beat.
Forefinger hitting practice (2, 3, 4 fingers reserved)
The picture above shows the middle finger, ring finger and little finger are kept on the corresponding phonemes when the index finger is playing.
If it is difficult to distinguish the relationship between semitones and full ranges when playing on a real piano, the following exercises are very meaningful. Specifically, it can be applied to the major and minor second tones that the middle finger hits above the original sound (the sound pressed by the index finger) to achieve the purpose of decorating the original sound head.
Middle finger (minor second) hit
The picture above is the exercise of the middle finger minor second hit (1-2 fingers are in a semitone state).
Middle finger (major second) hit
The picture above is the practice of the middle finger major second degree (1-2 fingers are in a whole tone state).
The following is an example of practice for ring finger tapping. Ring finger tapping is very common. In particular, it can be used in percussion or vibrato scores with "before and after sound".
Ring finger (minor second degree)
The picture above is the practice of ring finger close to the middle finger (2-3 fingers are in a semitone state). As long as you practice the skills in the picture above, you can deal with things such as: D (1 5) outer strings
The requirements for the playing skills of finger-pressing, vibrato ("tr") and singles ("ding" character) appearing in the music.
When practicing, the wrist and thumb should be relaxed, and the ups and downs of the fingers should be brisk and even. Note that the sudden bouncing motion of the raised finger is as important as the elastic "smack" of the lower finger. When practicing slowly, the fingers can be bounced high, and when fast, the fingers should be lowered.
Ring finger (major second degree)
The picture above shows the ring finger's major second pitch (2-3 fingers are in full tone). The practice points are the same as above.
In actual performance, there is very little chance of the little finger hitting. The main effect of the following example exercises is to improve the independence and sensitivity of the little finger, enhance the strength of the little finger, and improve the balance between the little finger and other fingers.
little finger second pitch
The picture above is a small second hit with the little finger (the 3-4 fingers are in a semitone state), which is the hit on the second position in the key of F.
little finger major second
The picture above shows the little finger hitting a major second (finger 3-4 is a whole tone).
The third pitch is the third (the minor third) that is played above the original to achieve the purpose of decorating the original head, and it has the style of some ethnic minorities. Below is an example of thirds practice.
minor thirds
The picture above shows the small third of the little finger (2-4 fingers are in the interval of a minor third). The picture shows the F key on the external strings.
major third
The picture above shows the ring finger's major third (1-3 fingers are a major third interval). The picture shows the internal strings in the key of F.
The left score is an example of the application of the major third in the erhu tune "Horse Racing".
