In addition to the four commonly used "basic finger shapes", erhu will encounter other finger shapes in practice, which are called "extended finger shapes" (variant finger shapes) here. These finger shapes are actually fingers Alien arrangement.

The application of "extended fingers" is also necessary. For example, the "223" finger type uses the stretching action of the little finger ("3-4" means forming a minor third), this "stretch finger type" is very common in folk music, especially suitable for music in the pentatonic type. This type of fingering is sometimes used to avoid changing the handle, to avoid unnecessary portamento or for the needs of timbre, and sometimes it can also introduce overtones (overtones of virtual pressing of the little finger), so it is often used.

Note: Be sure to enter the extended fingering practice after the four basic fingering exercises meet the basic requirements.

"111" finger type

The "111" fingering pattern belongs to the dense fingering. It is mainly used for fingering up and down the chromatic scale. In chromatic phrases, dense fingerings are often used instead of the same finger sliding. Use dense fingering to make the sound clear without glissando, and each sound is smooth and clear.

This kind of intensive fingering is needed for the "Bee Flying Dance" in the Erhu grading test, which starts with the descending phrase of the chromatic scale (ie, the first beat of the 1st bar of the left score is fingered on the inner string of the erhu).

The picture above is the "111" finger shape on the third position external string. When practicing the "111" finger shape, pay attention to the following points:

1. When pressing the fingers, the four fingers are basically close to each other, and each adjacent finger is a minor second, which corresponds to the semitone relationship between the adjacent fingers on the real piano.

2. The interval between fingers 1-3 or between fingers 2-4 is a major second, for example, the interval between 2-4 refers to "c2-d2" is a major second.

3. The interval between fingers 1-4 is a minor third.

 Note:

1. It is not easy to pull the continuous semitones in the high position, especially for those with thick fingers. At this time, the techniques of "moving the finger" and "letting the finger" must be used.

2. In practical applications, the "111" finger pattern and the "finger shift" playing method are often combined.

"112" Finger Type

As shown in the picture above, pay attention to the following points when practicing:

1. The interval between the index finger and the little finger is a major third.

2. The 1-2-3 fingers are pressed on the adjacent holes of the phoneme bar (semitone), while the 3-4 fingers are pressed on the holes in the other row of the phoneme bar (whole tone).

Note: 1-2-3 fingers should be close together, but the degree of closeness is different, 2-3 fingers should be closer than 1-2 fingers.

"113" finger type

The "113" finger pattern is also called the "lower 3" finger pattern. This finger pattern is often formed by the middle finger and the ring finger approaching the index finger, while the 1-4 finger tone is still a perfect fourth finger frame (note and "" 213" finger type difference).

Note: When practicing on the real piano, the little finger will often fail to press the sound (lower) due to the upward movement of the ring finger. It is very easy to find out whether the finger is in place when practicing with a sound bar.

"121" finger type

The picture above shows the "121" finger shape. When practicing, you should pay attention to:

Fingers 1-4 are major third intervals, fingers 1-2 and fingers 3-4 are pressed on the adjacent holes (semitones) of the phoneme bar, while fingers 2 and 3 are pressed on the phoneme bar. On the hole position (whole tone).

"211" finger type

The picture above shows the "211" finger type. Note: Fingers 1-4 are the major third interval, and fingers 1 and 2 are pressed on the holes of the phoneme bar (whole tone). 2-3, 3-4 fingers are pressed on the adjacent holes of the phoneme bar (semitone).

2-3-4 fingers should be close together.

"213" finger type

The "213" finger type is widely used in traditional handle positions. In the new handle position, the biggest advantage is that it avoids changing the handle. When practicing, keep the following in mind:

1. One of the characteristics of the "213" finger pattern is that the frame between the fingers 1-4 is already a perfect fifth, and the interval between the fingers 3-4 is a minor third (equivalent to three semitones).

2. The joints of the little finger should be in an arc shape, especially the joint in the middle should not be in a straight state.

3. Those with shorter fingers can place the finger on the ring finger according to the center of gravity of the finger, and the thumb can be moved down appropriately (closer to the 2 fingers). In the initial practice, the little finger is very laborious, but it is very helpful for training the root tendons of the fingers. The practice time should not be too long, and the fingers will be relaxed and natural only if they are practiced intermittently and persistently.

"231" finger type

The picture above shows the "231" finger type. Note when practicing: 2-3 refers to a minor third relationship, and 3-4 refers to a semitone relationship. Keep the second finger still during the exercise.

"311" finger type

The picture above shows the "311" finger shape. Note: 1-2 refers to a minor third relationship, and 2-3 and 3-4 refer to a semitone relationship.

When practicing, keep the second finger still, and the fingers 2-3-4 should be close together.

"312" finger type

The picture above shows the "312" finger type. The characteristics of this finger type are: 1-3 fingers and 2-4 fingers are in a minor third relationship, while 2-3 fingers are in a semitone relationship.

Note: In the second position, if the index finger is pressed back, it is often a "312" finger type.

"321" finger type

The picture above shows the "321" finger type. The "321" finger type is used more in the first position of the multi-scal.

Note: Same as the "312" finger shape in the above picture, you can practice the "321" finger shape in the second position (the way to press the index finger back). When practicing, the position of the thumb can be moved slightly to the upper end of the phoneme bar (in the direction of the pound).
