How is the erhu tuned?

The tuning method of erhu strings is 1. Approximate tone: use a sound of a small group of standard pronunciation devices as the standard tone, that is, the 5 so sound in D tone. By rotating the outer strings of the erhu. Then, using the standard pronunciation device, the inner chord is tuned to D key in the same way, that is, 1 do key in D key. The pitch of the erhu is 1.5, which is the same as that of the sound generator. 2. Fine-tuning: Select the mode of the electronic tuner as "erhu tuning mode", place it near the erhu drum, and then pull the slow longbow of the outer string with relatively uniform force. The pointer will swing left and right on the instrument according to the slight change of sound. The pointer is between 0 and -50, and the red light is on, indicating that the sound is low; On the contrary, when the red light is on, it means the sound is high; When the pointer is in the middle of 0 and the green light is on, the pitch is accurate. /iknow-pic.cdn.bcebos.com/3b292df5e0fe9925d4187e513ba85ef8db1719e "target =" _ blank "title =" ". /iknow-pic . cdn .

Several factors affecting the tuning of erhu: 1. Bowing strength; 2. The external environment (quiet); 3. The weight line of erhu is aging (often manifested as the pitch difference between the empty string bow and the push bow, and the push bow is low). How to master the intonation of erhu: 1 Accurate tuning: Whether using traditional Andhadhun or electronic organ, the accuracy of the performer is very high. If you are not sure about the fixed pitch, especially for beginners, it is recommended to download special erhu tuning software on your mobile phone, and the accuracy of the software even exceeds the human ear. 2. Too much or too little finger distance change: because the tuning of erhu often changes the fingering of semitone; The semitone of G is between the first and second fingers of the outer string, but the inner string is between the second and third fingers. The semitone of F key is between three or four fingers, so we should strengthen the practice of mode scale according to the fingering of different keys, and pay attention to the change of finger distance of each key. 3, changing the handle is easy to run off: moving too much or not in place when changing the handle will cause inaccurate sound. To ensure the accuracy of changing the handle, players should have the concept of pitch after changing the handle. 4. Incorrect vibrato: When you are a beginner, because you can't master the unity of the amplitude, speed and weight of vibrato, it often causes the voice to drift. At this time, the amplitude, strength and speed of wrist and palm vibration should be controlled by auditory adjustment until the strings make a harmonious and pleasant sound. References:
