2. When playing this tuner in the future, this twelve-average law is a good thing, so you can check your pitch at any time. First, we must press the red button to turn on the tuner, and then press the m button to adjust the preparation to the twelve-average law.
3. Turn the tuner, adjust it to a proper angle and clamp it on the erhu pole.
4. After tuning the erhu, start to find the next sound with the tuner. There are too many tones. Let's say it with an f key F adjust the cutting position, where the index finger is pressed 1, 5.
5. Then use the bow to pull the inner chord, and move the hand position slightly until the F key is displayed on the tuner and the color is green, and determine the positions of F keys 1 and 5. Just press the other sounds in order. When practicing by yourself, you can use this method to adjust the pitch from time to time without missing too much.
