One of the distinctive features of "Rain Alley" at the phonetic level is its strong musical beauty. This kind of musical beauty is mainly caused by the use of techniques such as the repetition of words and phrases and the regular repetition of rhymes. The repetition of words and phrases, such as: in the last stanza of the poem, except for changing "meeting" to "floating over" in the first stanza, the other words and phrases are exactly the same; this method of starting and repeating not only makes the content of the whole poem It echoes the beginning and end of the poem, and makes the basically the same speech flow reappear in the poem (repetition is one of the basic means of expression of music), thereby enhancing the musical feeling of the whole poem. In addition, there are repetitions of words and phrases in each stanza of the poem; such as: "long, long" in the first and last stanzas; "the same color as lilacs, the same fragrance as lilacs, the same sadness as lilacs" and "the same sadness as lilacs" in the second stanza. "Mourning in the rain, lamenting and wandering"; "Like me, like me" in the third stanza; "Like a dream, like a dream, sad and confused" in the fourth stanza; "Like me, like me" in the fifth stanza Far away, far away"; in the sixth stanza, "her color has faded, her fragrance has dispersed" and "eyes like breath, melancholy like lilacs" (variable repetition); this kind of repetition of words and phrases The repeated use of da in the poem and the echoes of certain repeated forms in the poem give this poem a very strong musicality. Regular repetition of rhymes: There are seven stanzas in the whole poem, each stanza has six lines. The number of words in each line varies, but overall it is repeated regularly. The poem uses rhyme to the end (rhyme with ang). The rhyme is repeated at the end of each line that is not far apart, and each stanza rhymes two or three times; some of the same words also appear multiple times in the rhyme. , such as "rain lane", "girl", "fragrance", "melancholy", "eyesight", etc. The repeated use of this rhyme causes the sound (ang) of the rhyme to be repeatedly felt in people's hearing, thus creating a looping musical effect. When we read this poem, our auditory feeling is like listening to a soft and soothing meditative serenade. The melody, which is full of loneliness, painful feelings but also makes people feel sweet, echoes repeatedly in our hearts.
