The tones from high to low are C,D,E,F,G,A,B, and boys are generally between E and F.

Tonality, which refers to the mode category and tonic height. In music, the tonic is the core of melody and harmony, and other sounds are subordinate to it and finally stop at the tonic. Such music is tonal music. ?

the sound frequency is called Pitch, which is one of the three main subjective attributes of sound, namely volume (loudness), tone and timbre (also called timbre). Indicates the degree to which people's hearing can distinguish the pitch of a voice. Tone is mainly determined by the frequency of sound, but also related to the intensity of sound. For pure tone with a certain intensity, the tone rises and falls with the rise and fall of frequency; For a certain frequency pure tone, the tone of low-frequency pure tone decreases with the increase of sound intensity, but the tone of high-frequency pure tone increases with the increase of sound intensity.

Extended information:

1. Scale

refers to the tones in a mode, starting from a certain pitch, that is, from the tonic, and arranging the notes from low to high according to the pitch order. Such a tone series is called a scale. The scale from low to high is called ascending, and from high to low is called descending. The scales we are talking about today are mainly major scales (major) and minor scales (minor).

pentatonic scale

a scale consisting of five tones. Mostly used in the mode of national music. Such as do, re, mi, sol, la, (do).

third, a major mode

mode. Seven-tone scale, the interval between adjacent two tones is divided into whole tone and semitone. Its scales are full tones except for the semitones between the third and fourth tones and between the seventh and eighth tones. The colors in major are clearer.

fourth, Minor mode?

as a mode, the seven-tone scale has four forms: "natural minor", "harmony minor", "melody minor" and "modern minor scale". The color of minor is generally darker than that of major, and it is often used to express sadness and melancholy. Natural minor (minor scale) is different from two or three tones and five or six tones

Five, just into the law

is different from twelve average laws. The relationship between each tone and the tonic in a scale is a pure interval. Because the semitone formed in this way can't be divided into averages, it can't be transferred casually, and it has been eliminated by history.
