Which of the following best describes homophonic texture?

Homophonic texture is characterized primarily by a single melody that is supported by harmonic accompaniment. In this context, the term "homophonic" indicates that there is a clear and prominent melodic line, while the other voices or instruments provide chords or harmonies to enrich the sound and support that melody. This texture is distinct from polyphonic texture, where multiple independent melodies are interwoven, and from monophonic texture, which would consist of a single melody without any harmonic support.

In this case, the description of a single melody with chordal accompaniment aligns perfectly with the definition of homophonic texture, showcasing how the melody is the focal point of the musical composition, while the accompaniment works to enhance it. The other options depict different musical textures or concepts that do not align with the characteristics of homophonic texture.
