Final answer:
Billy Joel uses rhyme to establish unity between the lines in the song 'For the Longest Time'.
Step-by-step explanation:
Billy Joel uses rhyme to establish unity between the lines in the song 'For the Longest Time'. The lines in the song follow a consistent rhyming pattern, with alternating end sounds.
For example, in the excerpt provided, the first and third lines rhyme with each other ('tonight' and 'write'), as do the second and fourth lines ('do' and 'time'). This repetition of sounds helps create a sense of cohesion and unity in the song.
In the excerpt from 'For the Longest Time' by Billy Joel, the technique used to establish unity between the lines is D. rhyme.
Rhyming occurs at the end of the second and fourth lines ('tonight' and 'write', 'you' and 'do'), providing a musical and poetic connection that ties the lyrics together.
This use of end rhyme creates a memorable and harmonious effect, contributing to the song's catchy quality.
