Related introduction:
The staff mainly serves keyboard instruments, and being familiar with the staff is the foundation for keyboard players to play well. The staff, as its name implies, consists of five elements. Indeed, it is composed of five parallel "horizontal lines" and four parallel "spaces", and their order is counted from bottom to top.
Compared with simple notation, the advantage of staff is that it can display the sound level intuitively and clearly. For example, those complex harmonies (there are several sounds in one position at the same time) are easy to identify and the vision is very clear.
Extended data
The earliest birthplace of staff is Greece, and its history is much earlier than that of simple staff. In ancient Greece, the main form of music was vocal music, and the pronunciation of lyrics was expressed by letters such as A, B and C. In Roman times, another symbol was used to express the level of sound. This notation, called Neuma, is the embryonic form of the staff.
When the staff was introduced into China, it was first recorded in Yi Xu in 17 13, in which the staff, scale and volume names were described. The staff was gradually spread and used in China, but it became popular after the middle of19th century with the preaching of western missionaries and the establishment of new learning.
