Music theory, as its name implies, is the theoretical knowledge of music. Music is a subject, such as Chinese, mathematics and English, which has its own theoretical knowledge. Learning music, music theory is the theoretical knowledge of music. Learning music, vocal music (singing) and instrumental music are inseparable from the three elements of music: melody, rhythm and harmony. These three elements can also be said to be three outlines for learning music, and all our knowledge of music theory is centered around these three outlines. The first element: melody

Melody is expressed in plain language. For example, the songs we usually listen to contain melody, but the lyrics are integrated with the melody. If the lyrics are removed, do, re, mi, fa, sol, la and si sung by notation are melodies. The smallest unit of melody is scale, which is like Chinese characters, and sentences are the melody of music. In addition, there are musical instruments, such as flute, erhu, violin and cucurbit ... The music we hear is also melody.

The second element: rhythm

Rhythm, in plain language, is the rule that constrains melody. Rhythm includes: beat, strength and notes. The beats of common songs, such as four or two beats, four or three beats, four or four beats and eight or six beats, are indicated by the number in front and the number in the back, such as four or two beats. The numbers in front of them indicate that each bar has two beats. Strength is a kind of rhythm of music. For example, the law of strength in 42 beats is: strength; The laws of the strength of four or four beats are: strong, weak, sub-strong and weak; The laws of the strength of four or three beats are: strong, weak and weak; The law of the strength of the eight-six beat is: strong, weak, weak, sub-strong, weak, weak. Show strength when singing and playing musical instruments. Strength can understand the breathing of adults. Notes indicate the length of the sound. Common notes include whole notes, half notes, quarter notes, eighth notes and dot notes.

The third element: harmony

Harmony is what people often say about chords. In fact, chords are only a part of harmony, including the knowledge of chord series and chord connection. Harmony is the most complicated of the three elements of music, and is usually widely used in piano and guitar. Chord refers to the combination of three or more sounds superimposed according to a certain relationship, and chord connection refers to the arrangement of chord sequences according to a certain law. Harmony serves the melody and plays the role of contrast and beautification.
