In order to play the Guzheng effectively you will need to evaluate your posture to better focus your body when playing. This guide and video will serve as a resource you can refer back to to make sure your posture is optimal.
You will need a stool similar to this one 
– about 16-18 inches high. Even better if it’s adjustable to find your personal height more effectively. You can find this one on Amazon
Sitting Position
Next position yourself so that your right shoulder is inline with the ‘Yue Mountain’ – the bridge on the head – near the tuning pegs. Please refer to our Parts Of The Guzheng blog post if these terms are unfamiliar.
Line up your belly button with the first movable bridge. The distance between your belly and the instrument should be about 2 closed fists distance – or about 6-8 inches. Keep your back straight and your shoulders relaxed.
Hand Shape
For our study on Guzheng Posture we will now move on to hand shape. The basic hand shape should be very relaxed, and it looks a little like you are holding an apple towards the ground. A ‘C’ shape is formed by your thumb to index finger
Wrist placement is important on the Guzheng, as it has a curved soundboard. There are 3 basic wrist angles depending on where you are playing on the instrument.
Playing on the bass strings your wrist will be slightly up 
If you are playing in the middle range your wrist would be mostly flat 
Playing the higher string would have your wrist a little bit lower
Beginners often have trouble the ‘flat’ and ‘up’ wrist angle. Be sure to pay attention and be mindful when using those positions. The wrist is meant to adjust its angle as you play different registers.
Thanks for reading this blog on Guzheng Posture. Take the time to develop correct posture and your Guzheng playing will benefit from it.
