All drum faces have a certain area, and different drum faces will have different timbre when struck

This means that the timbre of the drum is directly related to the accuracy of beating. It may not be difficult for you to aim at the position and knock once, but it is a matter of Kung Fu to hit the center accurately every time, no matter how fast or slow.

Secondly, we should ensure the accuracy of the time value.

We often have such an analogy when describing the structure of an orchestra. The timpani is the third conductor of an orchestra, which shows the fundamental significance of rhythm for music performance.

Therefore, it is not advisable to play fast and slow, and it is not advisable to play faster / slower. Whether it is the 16th minute note, or the rhythm of the first 8 and the last 16, or the attachment and segmentation, if you want a stable rhythm, you must accurately grasp the time value of each note, which can not be long or short.
