The right pedal [sustain pedal] is generally represented by the flower Ped. (abbreviation of Pedal) and the eight-pointed star represents release. The simplified notation can use the regular form Ped., the regular form P., the curly form P represents stepping, and the six-pointed star and the four-pointed star represent putting.

Piano scores are usually recorded in five-line staff (usually with two-line staffs, that is, treble and bass staffs). Five-line musical notation is currently the most common notation method in the world. A method of recording music on five equidistant parallel lines marked with notes and other symbols of different durations.

The predecessor of staff notation can be traced back to the Newham notation and measured notation in the Middle Ages. Newm notation uses horizontal lines as the standard and uses symbols to indicate the pitch of the notes, but does not show the length of the notes. This notation began to appear in European Catholic churches in the 7th century. Initially, only one line was used to represent the F pitch. In the 11th century, it was gradually developed into four lines by Guido of Arezzo.

Stipulate that the pitches are d, f, a, and c, and draw the f line in red and the c line in yellow (later becoming the origin of the treble and bass clefs in the staff). In the 13th century, someone used the fifth line, which became the predecessor of the staff. In the 16th century, the method of adding lines was introduced to make the recording of pitch more complete.

The staff was introduced to China. The earliest written record was the sequel to "Lü Lu Zhengyi" in 1713. The book recorded the staff, scales, roll calls, etc. Staff notation was gradually spread and used in China, and was promoted with the spread of Western missionaries and the establishment of new learning after the mid-19th century.
