What do you mean by "leaning alone in the dense bamboo while I play the piano and hum a song"?

From Zhu written by Wang Wei in Tang Dynasty.

I leaned alone in the dense bamboo, playing the piano and humming a song.

It's too light for anyone to hear, except my partner, Mingyue.

Selected from Notes on Wang Youcheng's Collection is the seventeenth of the twenty poems in Wangchuan Collection. Zhuliguan: A scenic spot in Wangchuan Villa. There are bamboo forests around the house, hence the name.

Juan: A deep bamboo forest.

Xi O: The mouth makes a long and crisp sound.

Deep forest: refers to "secluded forest".

Taking pictures: corresponding to "sitting alone", it means that there is no one around, only the bright moon seems to understand and wants to take pictures.

This is a poem describing the leisurely life of a hermit, depicting the leisurely life of a poet sitting alone under the moon playing the piano. This little poem has four sentences. Looking at it separately, there is neither touching scenery nor touching love; I can't find out which word is poetic eye, and it's hard to say which sentence is warning. Moreover, the words used in poetry are used to create language and scenery (secluded, deep forest, bright moon), and people (sitting alone, playing the piano, whistling) are extremely inconspicuous. But its beauty lies in its natural and simple style, which depicts the fresh and attractive artistic conception of the secluded forest on a moonlit night. The night is quiet and beautiful, which contains the special artistic charm of beauty and has become a masterpiece through the ages. Playing the piano and whistling reflects the silence of the bamboo forest on a moonlit night, and the darkness of the deep forest is reflected by the light and shadow of the bright moon. The surface seems dull and seemingly casual, but in fact it is ingenious.
