How to improve the proficiency of playing dulcimer left hand quickly

The basic bamboo method of dulcimer is alternating hands. There are two traditional bamboo methods: left bamboo method and right bamboo method. If you don't practice piano for a long time, you will be born. If you want to recover as soon as possible, you should practice from the wheel tone and play alternately with your right hand or left hand. The volume and timbre should be consistent, and the shoulders and wrists should be relaxed from slow to fast. Pay attention to the strength of your left hand and balance the strength of your two hands when practicing. You can also practice bamboo with your left hand and cross notes and broken chords with your right hand. Practice slowly first and then quickly, and don't lose the sound or the notes are unclear.
