You are listening to a Bach two-voice keyboard invention. Both voices move with their own rhythmic patterns and melodic identities simultaneously, and neither clearly 'accompanies' the other. What texture is this?
AMonophonic — two voices in unison create a single line
BHomophonic — one voice provides the melody while the other provides harmonic support
CPolyphonic — multiple independent melodic lines of roughly equal importance
DHeterophonic — two different versions of the same melody played simultaneously
Polyphonic texture is defined by multiple independent melodic lines that are roughly equal in importance — no single line is 'the melody' supported by background material. In a Bach two-voice invention, each voice has its own rhythmic and melodic profile, and the listener can follow either independently and find a coherent melody. Homophony (option B) requires one voice to be clearly subordinate as accompaniment. Monophony (option A) would require the voices to share the same single line.
Question 2 Multiple Choice
A four-part choral arrangement has the soprano singing a recognizable hymn tune while the alto, tenor, and bass parts fill in harmonic support with smoother, slower movement. A student identifies this as polyphonic because four voices are present. What is wrong with this analysis?
ANothing — four independent voices always creates polyphonic texture
BThe number of voices is irrelevant; only the register matters for classifying texture
CPolyphony requires all voices to have independent melodic identities; here the lower three voices are subordinate accompaniment, making it homophonic
DThis is actually monophonic because only the soprano carries the melody
The key criterion is not the number of voices but their relationship. Polyphony requires each voice to have independent melodic importance — the listener should be able to follow any voice and find a complete, interesting melody. In this choral arrangement, the lower voices provide harmonic filler that supports the soprano's melody rather than competing with it as independent melodies. That subordinate relationship is the defining feature of homophony. Four voices can create homophonic, polyphonic, or even heterophonic textures depending on how independently they behave.
Question 3 True / False
In polyphonic texture, the listener's attention can shift between voices because no single voice completely dominates the foreground.
TTrue
FFalse
Answer: True
This is the hallmark of polyphony. Because multiple voices carry roughly equal melodic weight, the listener is not locked into following a single foreground line — attention can move to whichever voice is most active or interesting at any moment. This creates a sense of intricacy and busyness that distinguishes polyphony from homophony, where one line clearly commands the foreground and the others recede into the background.
Question 4 True / False
A solo violin playing a melody while a piano plays chords beneath it is an example of monophonic texture, because the violin is the main complete melodic line.
TTrue
FFalse
Answer: False
This is homophonic, not monophonic. Monophonic texture means a single unaccompanied line — no harmonic support at all (Gregorian chant is the canonical example). The moment an accompaniment appears, even a subordinate one, the texture becomes homophonic. The presence of piano chords beneath the violin melody creates the characteristic homophonic foreground-background relationship: a melodic line with harmonic support. The fact that the violin is the 'only complete melody' is exactly what homophony looks like.
Question 5 Short Answer
What is the essential difference between homophonic and polyphonic texture, given that both can involve multiple voices sounding simultaneously?
Think about your answer, then reveal below.
Model answer: The difference lies in the independence and equality of the voices. In homophonic texture, one voice carries the melody and the others are subordinate — they provide harmonic support without competing for the listener's attention. In polyphonic texture, multiple voices have roughly equal melodic importance and independent rhythmic/melodic identities; no single voice clearly dominates, and the listener can follow any voice and find a coherent melody. The number of simultaneous voices is not decisive — a two-voice texture can be homophonic if one voice accompanies the other, and a four-voice texture can be homophonic for the same reason.
The concept of independence is what separates the two textures. Students often focus on voice count, but the question is always: are these voices of roughly equal melodic weight, or is one the melody and the rest support? That relationship defines the texture.
