Firstly, practice:

1. As long as conditions permit, try to practice the empty string for a while in the morning. Practice the four string and five face full bow and split bow in the morning, improve the accuracy of movements and postures, and then practice the scale. Because people's attention is very focused and easy to remember in the morning, practicing the empty string is a basic skill. Even world masters must practice it every day. In addition, as long as you have free time to do auxiliary hand exercises, do not interrupt. Persistence is the foundation. In this way, your bow will definitely make great progress in five to seven years and will emit rich and full-bodied sound.

2. Before playing the piano, first use soap and hot water to heat your hands. As long as you persist for a few years, your hands will be very soft, flexible, and delicate. At the same time, it is easy to set your hand shape. Heating your hands once is almost equivalent to practicing the piano, and you will quickly adapt to the feeling of the piano. This is not just my experience. If you don't believe me, you can try it. A professional just needs to look at your hands and immediately know what kind of level and type you are. Don't say you are a farmer or a worker. During the difficult period of your youth, we secretly worked on construction sites abroad for three years. We worked 12 hours a day and arrived at the base at 10:30 pm tired and deformed. We still persisted in practicing for one or two hours to adjust our mentality. Must Practice GDAE Practice the accuracy of movements and postures, as well as hand movements, with the full bow and split bow of the five face empty string. Then practice the scale, and finally pull the etude. It is not necessary to pull the etude completely. It is best for amateurs to practice selectively to quickly advance their progress.
