Music notes are represented by seven Arabic numerals: 1, 2, 3, 4, 5, 6, 7.
Note names: C, D, E, F, G, A, B.
Roll call: do, re, mi, fa, so, la, si.
The symbols used to record music are called notes. Singing or playing musical instruments are notated using notes.
Extended information
The structure of the note: The oval part of the note is called the "note head". The note head can be divided into a solid note head and a hollow note head (the pronunciation of the note is determined by the note head). (determined by the position of the head in the staff), the straight line part on which the note head rests is called the "stem", and the part above the note head that emits a wave-like shape is called the "tail".
Any note has a note head. Only whole notes and half notes have hollow note heads. Only whole notes have no stems. Only whole notes, half notes and quarter notes have no stems. The more symbols there are, the more symbols there are. The shorter the note duration (the duration decreases by 1/2 for each additional symbol).
Division of notes: There is a pattern among these seven notes, mi to fa, si to high note do are semitones. On the guitar, two adjacent frets are semitones. For example, the first string on the 1st fret is mi, then the first string on the 2nd fret is fa. On the guitar, one fret apart is a whole tone. For example, the first string on the 1st fret is do, then the first string on the 3rd fret is do. It's re, separated by 1 fret.
