Homophony is a type of musical texture that consists of a single melodic line accompanied by chords. The chords provide harmonic support for the melody, but they do not compete with it for attention. In Someone Like You, the piano provides the melodic line, while the guitar and drums provide the chords. The chords are strummed in a simple pattern, and they do not vary much throughout the song. This creates a sense of unity and cohesion in the song's texture.
Polyphony is a type of musical texture that consists of multiple melodic lines that are played at the same time. In contrast to homophony, the melodic lines in polyphony are of equal importance, and they compete with each other for attention. There is no single dominant melody in polyphony, and the texture is often more complex and varied than homophony.
Someone Like You is not polyphonic because it does not have multiple melodic lines that are played at the same time. The song is homophonic because it has a single melodic line that is accompanied by chords.
