Sound is an important characteristic of poems. Traditional sound rhythm is a gradual process from music rhythm to linguistic rhythm, from natural rhythm to man - made rhythm, from one rhythm to multi - rhythms, from outer rhythm to inner rhythm. The basic idea lies in the fact that the root of sound rhythm is attributed to the life rhythm, and the natural sound rhythm is intended to be one with man - made rhythm. These experience works as reference and also as reference of constructing modern poetics.
