Generally speaking, disyllabic steps refer to two-word words, while monosyllabic steps are words. For example, the mountain covers the white sun, so it is the end of the day//mountain//,which is the end step. Generally speaking, as you said, in five-character poems, monosyllabic steps often appear in the middle or at the end. Such as "desert//solitary smoke//straight, long river//sunset//round". If we have to put step by step at the beginning, we will form the characteristics of the word "read//Wu Gou//,hit the railing//times".
As for the seven-character poem, it is often the structure of 223, such as "the wind is rushing//the sky is high//the ape cries/mourns", and the ape mourning here can also be divided into ape mourning/mourning. Of course, there are exceptions: "Three Wan Li//rivers//east into the sea, five thousand miles//yue//on the skyscraper." So this sentence itself will be awkward.
In fact, in Chinese, a syllable or a combination of syllables will form a "pause", which is a sound step. For example: advise you to do more//have a drink. These pauses are all sound steps.
The division of steps needs to consider two aspects:
1, semantic integrity, that is, the premise of dinner, needs to be a man or a man's word needs to be a complete expression of meaning.
2. The syllables are complete, and common poetic styles such as Siyan, Wuyan and Qiyan have long formed a fixed rhythm division form, such as Siyan and Ercan (2-2 sentence pattern), Wuyan Sancan (2-2- 1 or 2- 1-2 sentence pattern) and Qiyan Siwan (2-2-2).
The above is a simple description of the steps in ancient poetry.
