Two, three, four, five, six, seven, eight as spectral characters to indicate the pitch of the scale

Two, three, four, five, six, seven and eight are used as clefs to represent the pitch of each tone of the scale.

In China's traditional notation, the two-four clef is an ancient stringed clef, with two, three, four, five, six, seven, eight as the clef indicating the pitch of each step of the scale. Ancient people used to describe the power of music by saying that "the sound of the music will never cease to resonate for three days". Unfortunately, there were no images or videos at that time, so it is impossible for later generations to realize the extent of the musical skills of the people of that time. However, through the study of ancient music scores and musical instruments, it is possible to understand the profoundness of ancient music.

The three and six of the spectrum distinguish between light and heavy, light three light six that is, three six two tones remain unchanged, heavy three heavy six that is, three six two tones raise two degrees, the shift occurs, due to the different string method at the same time close to the descending si and fa, and at times close to the si and the ascending fa. in addition to the five character tone also has the pitch change, known as the living five. These variations of light, heavy, and live give rise to four modes of different moods: light three light six (referred to as light six), heavy three heavy six (referred to as heavy six), light three heavy six (referred to as half light heavy), and heavy three heavy six live five (referred to as live five).

Light six tone three six two tone unchanged, the tune is light and active. Heavy six tone three six two tone must be aggravated, the tune is deep and majestic. The light triple six key is characterized by both light three and heavy six, and the tune is witty and fun. Live five tones should be elevated and greatly sliding back and forth, its sound is extremely unstable, three six tones should also have a certain regular slide, the tune is sad and sad.
