What people are accustomed to referring to as melody actually refers to the tune. Melody can refer to any musical sequence with pitch and rhythm. Melody is the basis for composing parts. Only when the melody is first formed can the part be produced (the part here refers to the position of a certain melody in music), thus producing a (composite) impact.

For example, the four parts in a four-part harmony each have their own melody progression, and a certain melody with a sense of tune will appear as the main melody part (usually the high voice part).

The parts of main-key music are interdependent, and the melody of only one part has a sense of tune, so we are accustomed to calling it the "main melody". Polyphonic music is music composed of melodies (melodies) with independent meanings that are combined with each other, and all parts have a sense of tune.
