I'm 12 and I love 2 song write so I hope this helps, (you can copy it... As if that wasnt obvious.. LOL)
I can never ever get you out of my head. Maybe it's the way you hold my hand, or the way I get lost in your beautiful eyes. I can't seem to get enough of the way they shine. You are my perfection, my forever, until eternity, we'll be together, and for if were far apart I'm now taking this chance to say. I've loved you in every single way, so please, don't ever forget about me.
Well you could start off with words from the heart and just put them in a sentence then all you have to do is add a tune and he'll love it no matter what
Well, you don't think about writing technique or style when you are expressing your thought to your beloved. My suggestion is to write whatever comes to your mind. The words which erupt from your heart always give everlasting impact. You can however, check other love songs to get some idea of love songs. Click this link
I got my music degree and I'm 18 take some advise from someone who's experienced. First write down how you feel about the person in notes or something put it in a poem and hit a beat while saying it and eventually you find a tune and a rhythm. It doesn't come in an hour a good true song takes days to write.
I am in the same situation.. :( we have been trying to find a good love song for us but we havent had any luck lately. So the only thing we can do is for me to write a song and I feel the same way you feel about your boyfriend so I am just trying to put it in a song but I want to make it good!!!
Oh how do I love thee? Let me count the ways; one lets have some fun, two I will walk with you to school, three you must know what you are to me, four, no! You can not yet score ,five but please lets keep it alive, six soon we will play titly wix , seven now we are pleased with the star from heaven, eight an when I am fat again because I am late, nine I am sure glad your mine, ten well maybe we should of stopd at eight instead of ten. Now that's poetic lol
