Texture and harmony types: identifying monophonic, homophonic, polyphonic and contrapuntal textures, and related concepts such as unison, harmony and imitation, in the Understanding Music question paper.

What this dot point is asking

Texture is how the musical lines and parts combine: whether there is one line or many, and how they relate. SQA Higher Music examines texture under the texture, structure and form heading. The Understanding Music paper asks you to identify a texture - monophonic, homophonic, polyphonic - and related concepts such as unison and imitation, by ear. This dot point sets out the texture and harmony-type concepts and how to tell them apart in an excerpt.

The answer

The texture concepts at Higher describe how parts combine. A monophonic texture is a single melodic line with no harmony (one voice, or several in unison). A homophonic texture is a single main melody supported by chordal accompaniment, the most common arrangement in songs and hymns. A polyphonic (or contrapuntal) texture has two or more independent melodic lines sounding together, each going its own way, as in a fugue or a round. Related concepts include unison (everyone playing or singing the same line together), harmony (notes sounding together to support a melody), and imitation (one part copying a phrase just stated by another, the basis of a round or fugue). In the listening paper you identify the texture by hearing how many independent lines there are and how they relate, naming the concept precisely.

The three main textures

The reliable way to tell the textures apart is to count the independent ideas and check for accompaniment. A monophonic texture has one line and no harmony. A homophonic texture has one main tune plus supporting chords. A polyphonic texture has two or more independent tunes at once. This three-way test - one line, tune plus chords, or many tunes - covers most questions.

Unison, harmony and imitation

Unison is everyone performing the same line together (in monophonic texture, or for emphasis). Harmony is notes sounding together to support or enrich a melody, the basis of homophonic texture. Imitation is one part stating a phrase that another part then copies, often a beat or bar later, the device that drives a round (such as a sung canon) and a fugue. Hearing imitation is a strong clue to polyphonic texture.

Hearing texture

Texture questions ask you to judge the relationship between the parts. Listen for whether there is one line or several; if several, decide whether they are a tune with accompaniment (homophonic) or independent melodies (polyphonic); and listen for unison passages and for imitation between parts. Naming the texture with its precise term is what scores.

Examples in context

Take a choral excerpt. It might open with all voices singing the same line together (unison, a monophonic texture), move to a verse of melody with chordal support (homophonic), and build to a passage where each voice enters in turn with the same phrase (imitation, a polyphonic texture). Three named textures, three possible marks.

Take an instrumental round. You might hear one instrument state a tune, a second copy it a bar later, and a third join with the same tune, so several independent lines weave together (polyphonic, with imitation). Naming the polyphonic texture and the imitation secures the marks.

Try this

Q1. What is a monophonic texture? [1 mark]

• What the marker wants. A single melodic line with no harmony (one voice, or several in unison).

Q2. How do homophonic and polyphonic textures differ? [2 marks]

• What the marker wants. Homophonic is one main melody with chordal accompaniment; polyphonic (contrapuntal) is two or more independent melodies sounding together.

Q3. What is imitation, and which texture does it signal? [2 marks]

• What the marker wants. Imitation is one part copying a phrase just stated by another; it signals a polyphonic (contrapuntal) texture.
