Why use simile?
Generally, a writer uses similes to enable the reader to imagine in his mind what the writer is saying. This is why a writer compares one thing to another with which the reader is familiar. The speaker compares his love to a red rose that has just bloomed. We are all familiar with a rose, so we are able to better understand the comparison. Most people are awed by the beauty of a "newly sprung" rose, so we can understand how the speaker feels about his love. He also compares to "the melodie/That's sweetly played in tune". Again, music is universal, so we can all understand how the speaker feels. We can imagine how we feel when we hear a beautiful piece of music played. It sends chills over us, and this lets us comprehend the speaker's feelings.
