In notation, the basic symbols used to express pitch and its relationship are seven Arabic numerals, namely 1, 2, 3, 4, 5, 6, 7, which are sung as do, re, mi, fa, sol, la and si, and are called roll calls.

Notes: 1, 2,3,4,5,6,7

Roll call: do, re, mi, fa, sol, la, si

In notation, whether the basic notes are high or low, the names of the volumes represented by the seven Arabic numerals are always the same. In the notation system, if the intervals between 1→ i or i→ 1 are arranged in high and low order, it is called a scale. Along the direction of 1→ i, a sound has more than one pitch; In the opposite direction i→ 1, one note is lower than the other.

In notation, the seven basic notes, 1, 2, 3, 4, 5, 6 and 7, represent not only the sound level, but also the basic unit of sound length, and are called quarter notes. Other notes are based on quarter notes and are represented by dashes and dotted lines.

Origin:

The rudiment of digital notation first appeared in Europe in16th century, when there was a Catholic monk named Suetti. He wrote music education songs with 1, 2, 3, 4, 5, 6, 7, and then wrote a booklet entitled "New Methods of Learning plainsong and Music". Westerners at that time paid great attention to personal achievements such as invention and creation and copyright, which is recorded in history.

18th century Frenchman named Rousseau; 1742, he read a paper "Suggestions on New music notation" to the French Academy of Sciences, and then mentioned this "digital notation". Since the middle of18th century, a group of French musicians, doctors and mathematicians have sorted out and perfected the "digital notation".

19th century, through the continuous improvement and popularization of P Garland, A Paris and E J M Xie Wei, it was widely used by the masses. Therefore, this notation is called "Jia-Pa-Xie notation" in the west.
