ABCDEFG represents the note name, which is the name given to the note with a fixed height.

Related introduction:

The ABCDEFG order from low to high is: C, D, E, F, G, A, B. These seven tones constitute the seven basic tone levels, which correspond to the sounds produced by the white keys on the piano.

The names of basic sound levels are marked in two ways: note name and solfa. The note name of each note level is marked with letters. The roll call is represented by pronunciation. The note names of the basic note level of C major and their corresponding roll calls are do, re, mi, fa, sol, la, and si.

Extended information

In the music system, the marks of the seven basic tone levels (note names and roll call) are used cyclically. However, the pitches of the note levels in each cycle are different, that is to say, although the note names (or solfeggios) are the same, the pitches are different.

When marking sound names, use uppercase or lowercase, or add subscripts after capital letters and superscripts after lowercase letters to distinguish them, that is, grouping of sounds. For example: C, B2, a, a1 (the following number "1" should be in superscript form), B2 (the number "2" should be in subscript form). The relationship between two adjacent tones with the same name is called "octave".
