The correct answer is texture.
In music, texture represents how we hear and interpret the layers of the music. It is one of the elements of music. The texture includes the tempo, melody, harmony, and rhythm used in the composition to produce an overall quality sound produced.
There are 4 types of texture in music. These are:
Monophony: this represents the characteristics of a piece that has only a primary melody and no secondary melody or accompaniment.
Polyphony: this is a musical texture consisting of several independent melodic voices, as opposed to music with just one voice or music with one dominant melodic voice accompanied by chords.
Homophony: this is a texture in which two or more parts move together in harmony, the relationship between them creating chords.
Heterophony: refers to the simultaneous performance by a number of singers or musicians of two or more versions of the same melody.
