I think if you are new to poetry, you need to know a little bit about meter. For meter poetry, meter has become a fixed formula. You can just look at it from the Internet, but if you want to learn how to write lyrics, I think you should have a book. Lyric score. "Bai Xiang Ci Pu" is very good.
Once you understand some metrical knowledge, you can read some poems (comments). I really like Wang Guowei’s "Human Poems", which is very insightful. Recently I was reading a book called "Poetry Notes" by Wu Xiaoru, and I gained a lot from it. You must first learn to analyze poetry, understand poetry, and appreciate poetry.
You should often write some poems, but while writing, you should read more books. Reading poems (comments) is one aspect. At the same time, you should also read some famous poems by the ancients and use the knowledge you have learned. Analyze it and read the comments of famous experts.
I think in addition to reading books about poetry, you can also read some books about aesthetics. After all, art is connected, such as contrast and unity, rhythm and rhyme in the basic principles of aesthetics. Suitable for poetry. You can also read some books on music. Rhythm is important in both poetry and music. After all, poetry and music are from the same family.
Actually, I am also a beginner and don’t know much about poetry. These are some of my opinions, I hope they are of some help to you.
