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

Tonality 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 end up on the tonic. Such music is tonal music. ?

The level of sound frequency is called pitch, which is one of the three main subjective attributes of sound, namely volume (loudness), pitch, and timbre (also called timbre). Indicates the degree to which human hearing distinguishes the pitch of a sound. Pitch is mainly determined by the frequency of the sound, but also related to the intensity of the sound. For a pure tone of a certain intensity, the pitch rises and falls with the frequency; for a pure tone of a certain frequency, the pitch of a low-frequency pure tone decreases as the sound intensity increases, but the pitch of a high-frequency pure tone rises as the intensity increases.

1. Scale (Scale)

Refers to each tone in the mode, starting from a certain pitch, that is, starting from the tonic. The notes are arranged in pitch order from low to high. This sequence of notes is called a scale. The scale from low to high is called ascending, and the scale from high to low is called descending. The scales we are talking about today are mainly based on the most common major scale (major key) and minor scale (minor key).

2. Pentatonic scale

A scale composed of five tones. A mode mostly used in folk music. Such as: do, re, mi, sol, la, (do).

3. Major mode

A type of mode. In the seven-tone scale, the distance between adjacent two tones is divided into two types: whole steps and semitones. Except for the semitone between the third and fourth tones and the semitone between the seventh and eighth tones, the rest of the scale is a whole tone. The colors in major keys are brighter.

4. Minor mode?

A type of mode. The seven-note scale includes "natural minor", "harmonic minor", "melodic minor" and "modern minor". "Four forms of musical scale". The color of the minor key is generally darker than the major key, and is often used to express sadness and melancholy. The second and third notes of the natural minor (minor scale) are different from the fifth and sixth notes. 5. Just intonation (Just intonation) is different from the twelve equal temperament. The relationship between each note and the tonic in the scale is a pure interval. Since the semitones formed in this way cannot be divided into equal parts, they cannot be modulated casually and have been eliminated by history.
