Writing is a skillful art form that many seem to hold in a low regard when compared to engineering, medicine, or athletics. The ability to articulate your thoughts and emotions in a provocative manner is the closest anyone can get to becoming immortal. Things that you will build deteriorate and change with the passage of time. Medicine can and will always improve upon itself. And the strongest, fastest, or fittest person on Earth will eventually pass away. However, if you write something, it becomes remembered by the public, records, and copies of it will exist and persist throughout history.
Therefore, there is little else more romantic than a poem - an immortal exclamation of one's affections to another. Love poems are typically short, beautiful, and highly expressive. They have to be. Love should be conveyed in little words, but still, have so much to say. It's why the phrase "I love you" has a lot of impacts. It's only three little words, but, those words say more than entire paragraphs.
In addition to this, love poems require an immense amount of thought and emotion to come out as fully intended by the writer. You can end up poring hours into every word; doing your best to make sure that nothing is left unexpressed. The practice of writing poetry is very much like this, but love poetry is especially like this. The emotions that you want to let out into the poem is also very draining. A love poem demands a heightened amount of emotion to it. That's why the best love poems come from the Romantic movement in literature.
The most important component of a love poem, and of poems in general, is without a doubt the way it is spoken out loud. When a poem is spoken out loud, the words should have good flow, and they should please the ears. If you can say a poem easily and it sounds like it has its own kind of musical quality, then it has fit the definition of what many would consider being "good" poetry. A love poem needs to not just touch the heart. It has to gently caress the ears, too.
Giving a love poem to someone you have feelings for shows a lot about you. It shows you have talent. It shows you are willing to devote hours just to composing some words on a piece of paper for one person. Most importantly, it shows that you are willing to risk hurting yourself if the poem does not connect to the person who receives it. Hopefully, that person understands all this. You can give them all the flowers, diamonds, and candy in the word, but it will never shape up to the power of a poem.
Love poetry is a rarity today. A deeply saddening notion. Anyone in a relationship should at least attempt the art of love poetry. It conveys a lot when you put effort and time into the composition of an intimate poem. Like all writing, poetry is immortal as should be the love for the person you are writing that poetry for.
