The horizontal s is an echo mark.

It is a melody pattern that progresses back and forth from four or five notes. The continuous echo composed of four tones starts from the upper second tone to the main tone, and then goes to the lower second tone to the main tone; the continuous echo composed of five tones starts from the main tone and is followed by the four tones. The echo is the same. Diacritical marks can also be added above and below the echo mark, and the echo can also be recorded between two notes.

The decorative sounds in the piano include echo, bass, bass, etc. Echo means starting from playing the second note above the basic note, then playing the basic note, then playing the second note below, and finally reaching the basic note. Boeing means that after the basic tone pops up, the upper second tone quickly pops up and returns to the basic tone. The lower tone is played in the same way as above, except that the upper second tone is changed to the lower second tone.

Extended information:

Piano scores are usually recorded in five-line notation. The earliest birthplace of five-line notation is Greece, and its history is much earlier than the simplified musical notation in digital form. In ancient Greece, the main form of music was vocal music, and the pronunciation of lyrics was represented by letters such as A, B, C...

In the Roman era, another symbol began to be used to represent the pitch of the sound. This notation was called "Newm notation", which was the prototype of the staff. The staff was introduced to China, and the earliest written record was the sequel to "Lü Lu Zhengyi" in 1713, which recorded the staff, scales, roll call, etc.

Staves were gradually spread and used in China, and were promoted with the spread of Western missionaries and the establishment of new learning after the mid-19th century. Compared with simple musical notation, the advantage of staff notation is that the pitch of the notes is clearly displayed visually.

For example, those complex harmonies (several tones appearing in one position at the same time) are easy to identify and the vision is very clear; in terms of expressing melody, especially the shape of many high and low tones is clear at a glance. , so the ones widely used internationally are basically staff notation.
