the names of the seven basic levels do, re, mi, fa, sol, la and si.

in the musical system, seven levels with independent names are called basic levels. These seven levels correspond to the sound made by the white keys on the piano now.

the pitch of the scale in each cycle is different, that is, although the sound name (or roll name) is the same, the pitch is different. When marking phonetic names, use uppercase and lowercase letters, or add subscripts after uppercase letters and superscripts after lowercase letters to distinguish them, that is, grouping phonetic names.

Basic Tone Words

There are two marking methods for the names of basic tones, namely, sound names and roll names, and the sound names of each tone are marked by letters. The roll call is expressed by pronunciation.

(About the relationship between sound names and roll names, we will explain it in detail in the later part of mode and tonality. ) Take C major as an example: from low to high, the basic tones in C major are marked as: C, D, E, F, G, A and B, and their corresponding roll names are seven pronunciations: do, re, mi, fa, sol, la and si.

In the musical system, the marks of the seven basic levels (sound name and roll name) are recycled. That is, after C, D, E, F, G, A, B, and then back to C, D, E, F, G, A, B or do, re, mi, fa, sol, mi, fa, sol, la, si, and so on.

However, the pitch of the scale is different in each cycle, that is, although the sound names (or roll names) are the same, the pitch is different. When marking phonetic names, use uppercase and lowercase letters, or add subscripts after uppercase letters and superscripts after lowercase letters to distinguish them, that is, grouping phonetic names.

such as: 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 sounds with the same name is called "octave".
