Novices' fingers will hurt, muscles will ache at the beginning of fitness, they will not adapt to the unit environment when they just join the work, and they will get angry when they just start eating Hunan spicy food. These situations are no different.
Cocoon planting is actually not an end, but a result. Finger pain is not only caused by lack of cocoon, but also by incorrect posture and force, which will lead to (at least aggravate) finger pain. Our goal is actually to practice the basic skills of the left hand, such as pressing the string position, exerting force and exerting force. To achieve this goal, we will get the additional effect of "picking cocoons" and solve the pain problem by the way.
It's not that I practice the piano to "make my fingers no longer hurt by long cocoons", but that in the process of achieving the purpose of "playing the piano well", my fingers have gone through the process from pain to no pain, from cocoon-free to cocoon-free.
Does it look more "scientific"?
