Also described as texture, refers to the organizational relationship between or among musical sounds.

The answer is phonic structure. In music, this also known as texture, It is how the harmonious, rhythmic, and melodic constituents are joined in a composition, thus defining the general quality of the sound in a piece. This is frequently labeled in regard to the density, or thickness, and range, or width, between lowest and highest pitches, in comparative terms as well as more specifically distinguished according to the number of voices, or parts, and the relationship between these voices. For instance, a thick texture covers many 'layers' of instruments. One of these layers could be a string section, or another brass. The thickness also is altered by the amount and the richness of the instruments playing the piece. The thickness differs from light to thick.
