In music, texture is how the [[melody|melodic]], [[rhythm]]ic, and [[harmony|harmonic]] materials are combined in a [[musical composition|composition]], thus determining the overall quality of the sound in a piece. Texture is often described in regard to the density, or thickness, and [[range (music)|range]], or width, between lowest and highest pitches, in relative terms as well as more specifically distinguished according to the number of voices, or parts, and the relationship between these voices. For example, a thick texture contains many "layers" of instruments. One of these layers could be a string section, or another brass.

The thickness also is affected by the number and the richness of the instruments playing the piece. The thickness varies from light to thick. A lightly textured piece will have light, sparse scoring. A thickly or heavily textured piece will be scored for many instruments. A piece's texture may be affected by the number and character of parts playing at once, the [[timbre]] of the instruments or voices playing these parts and the harmony, [[tempo]], and rhythms used.{{sfn|Benward and Saker|2003|loc={{Page needed|date=July 2015}}}} The types categorized by number and relationship of parts are analyzed and determined through the labeling of primary textural elements: primary melody, secondary melody, parallel supporting melody, static support, harmonic support, rhythmic support, and harmonic and rhythmic support.{{sfn|Isaac and Russell|2003|loc=136}}{{incomplete short citation|date=December 2021}}

Common types included [[Monophony|monophonic]] texture (a single melodic voice, such as a piece for solo soprano or solo flute), biphonic texture (two melodic voices, such as a duo for bassoon and flute in which the bassoon plays a drone note and the flute plays the melody), [[polyphonic]] texture and [[Homophony|homophonic]] texture (chords accompanying a melody).{{Citation needed|date=August 2015}}<!--Especially for the drone accompaniment, which is usually regarded as a type of monophony.-->
