How to play the 1234567 scale on the erhu

To play the 1234567 scale on both the inner and outer strings of the erhu, you need to master the skills of bowing and string changing, as well as the skills of finger manipulation, memorizing the pitch, and especially having a good concept of intonation. Because the erhu is not a fixed-pitch instrument, each tone is controlled by the player's finger pressing the strings. The subtle changes in the position and strength of the fingers on the strings will affect the accuracy of the pitch. The left hand's skill in bowing and string changing also affects the quality of the melody, the tone, the consistency, the roundness, and the jumps of the sound. So you need both hands to work well together.

Secondly, the position of 1234567 is different in different keys (different string positions).

The standard fixed strings of the erhu are D for the inner strings and G for the outer strings. In the case of the standard fixed strings, using different string methods, you can play a number of different tunes, and the scales (1234567) of the different tunes are not arranged in the same way. In the case of standard tuning, the common keys and their corresponding string patterns are: 1=D (1,5 strings), 1=G (5,2 strings), 1=F (6,3 strings), 1=bB (3,7 strings), 1=C (2,6 strings), 1=A (4,1 strings), and so on. For the specific string positions of the keys (the positions of the 1234567), please refer to the following chart:
