What is a chord?

Hello, according to your question, the interpretation of "major triad Chord" is as follows:

The first and third chords:

(1) A chord composed of three sounds in a three-dimensional relationship is called a triad. These three sounds, the bottom one is called root, the middle one is called triple, and the top one is called crown. Because the crown sound is five degrees away from the root sound, it is also called pentatonic scale.

(2) Example: C chord, 135, root sound 1, tenor 3, crown sound 5. The root sound 1 to trisyllabic note 3 is three degrees, and trisyllabic note 3 to pentatonic note 5 is three degrees, which constitutes the condition of three-degree superposition. According to the interval relationship, from the root sound to the pentatonic scale, it is five degrees.

Second, the classification of the underworld:

Triads are divided into major triad, minor chord, positive triad and negative triad. Let me briefly talk about the sound effects of several triads.

Major triad: bright color, suitable for some cheerful major songs, represented by capital letters.

Chord: the color is dim and sad. Suitable for some lyric songs in minor, such as capital letter roar and lowercase m, such as Am chord.

(1) Chords come from the Greek word χ ο ρ δ? A concept in music theory refers to a group of sounds with a certain interval relationship. Three or more sounds are vertically combined according to the overlapping relationship of three degrees or non-three degrees to form a chord.

(2) Third-degree chords: generally, there are three chords (three-tone chords), seven chords (four-tone chords), nine chords (five tones), eleven chords (six tones) and thirteen chords (seven tones). Non-third-degree chords usually include: hanging chords, strong chords (that is, fifth-degree chords) and so on. In that way

(3) However, there is no such thing as 32 chords, 40 chords or even 64 chords! Strictly speaking, "chord bell" is a commercial concept, which is not in line with music theory, but its timbre is fuller and rounder, and it can give people beautiful enjoyment in hearing. But in the industrial design of audio equipment, chords are also called polyphony, which means that multiple sound sources are pronounced at the same time. Generally speaking, on the piano, there are three chords and seven chords, and there are few nine chords. In guitar, chords are usually decomposed by sweeping sound, and another chord has many methods of bending sound.
