Simply put, melody is the beat of music,

while intervals are only divided into degrees, not melody.

The following is some information I found

About the division of musical degrees:

There are two elements, one is the degree of two musical notes, for example, 12 is two In degrees, 13 is a third, but the number of notes in the interval. To put it bluntly, it is the size of the two notes. For example, 13 is composed of two whole tones, which is a major third, and 24 is composed of a whole tone and a semitone, which is Minor third.

It is not necessary to memorize the number of sounds. Once you become proficient, quoting will become a burden.

You just need to memorize the common intervals. I will make a table for you:

Each group of sounds mentioned below is arranged from low to high, such as 1 in 31 is the high note above 3)

Pure degrees: 11, 22, 33,....

Minor second degrees: 34, 71

Major second: 12, 23, 45, 56, 67 (except for the natural tones related to the minor second, the intervals are all major second)

Minor third: 24, 35, 61, 72

Major thirds: 13, 46, 57,

Fine fourths: 14, 25, 36, 51, 62, 73 (fourths except 47)

Augmented fourth: 47

Minus fifth: 74

Pure fifths: 15, 26, 37, 41, 52, 63 (fifths except 74 )

What is melody?

A horizontal single-part progression with many independent tones that embodies the main idea or all the ideas of music, is organized using modal and rhythmic relationships, and is called a melody. In layman's terms, it means monophonic music and songs. Melody is the soul and foundation of music.

Melody can be divided into two types: vocal music and instrumental music. Vocal melodies are sung for the human voice. Therefore, it is very closely related to human voice and language. Its characteristics are: relatively narrow range, relatively simple rhythm, rich in singing and lyricism; instrumental melody is played for the musical instrument, which is directly related to the structure of the musical instrument. Generally speaking, instrumental music melodies have a wider range, greater changes in rhythm, speed, and intensity, and are full of technical skills. For example, the piano has the widest range.

Melody is an organic combination of many basic elements of music, such as mode, rhythm, beat, dynamics, timbre performance methods, etc.

Melody in multi-part music can be divided into "main tune music" due to different combination methods. That is to say, one voice (mostly the high voice) is the main melody, and the other voices accompaniment and background for it. There are several parts with the same melody, or they may be different, and they all have independent functions and are of equal importance. There is no priority in the progression, and no one is willing to set off the other. They do not give in to each other and are uncoordinated. The music formed by combining them together is called "polyphonic music".

Simply put, the continuous progression of single tones of different pitches and different durations constitutes a melody. Strictly speaking, the melody is composed of mode relationships and rhythmic beat relationships, and is independent. A monophonic progression of many notes. Melody organically combines all the basic elements of music (here refers to mode, pitch, rhythm, intensity, etc.) into a complete and inseparable unity. It is inconceivable that melody is separated from various other musical elements, because the performance and emotional power of melody are realized through the action and interaction of various elements of music. Melody can be divided into two types: vocal melody. Vocal melody is for human voices to sing. Generally speaking, its range is relatively narrow and its singing ability is its biggest feature. Instrumental melody is played by musical instruments. Compared with vocal melody, it has a wider range, greater changes in speed and intensity, and is rich in rhythm and technique. However, singing is also important to the performance of instrumental melody. meaning.

The ways of melody progression can be roughly divided into the following four types: 1. Progression. That is, the melody proceeds according to a scale, which can be ascending (12345) or descending (54321). 2. Jump in. Jumping three or more times during the progression of the melody is called jump (135 or 531). 3. Repeat the same sound. The same sound appears continuously (1155665, 4433221). 4. Mold advance, that is, repetition at different heights (123, 456, 654, 321).

In addition, the melody can also be changed and developed through certain means, thereby expanding the scope of the melody and enriching the content of the melody.
