When writing a song, think of it as your journey in life. Just as like when you are talking to a friend. However it can be a difficult task as it requires creativity. Whether this is relating to your life experience, someone else's life or both.
When writing a song you can either write the words first then melody comes after. However this is a bit tricky as it requires you to get the right tempo, rhyme, music. When I compose my own song. Most of them were written with the music already been created.
Start with Basics
Once my teacher told me during my music lesson. Start with the basics. Yes! it sounds really boring. However, in any aspects of life whether it is learning how to drive to learning how to ride a bike. It is always believe that we learn from the basics. Can you imagine if your parents told you, you must walk now or run now. Baby steps! we learn slowly, and we grow from there.
In writing songs, it takes years of experience. When I say it like. I don't mean you have to get a degree to master it. Again, it's all about the experience. You have to start with the basics.
I know what you're thinking, how can I get idea from writing a song if I don't at least copy some of it? Well! remember when your teacher asked you don't copy and paste from a website or from a book? Your teacher eventually found out that you did. You got in trouble and you wasted your time and effort, well!not form copying from checking the source.
I will tell you now that every person's story is unique, same goes with everyone's finger prints. You have unique story, You have unique life experience. Use that as your reference.
Ask for Feedback
Now you can't work by yourself and expect people to listen to your song, ask around. You can start with your family, friends. ask them what they think about you wrote. Don't get disappointed if you get some negative feedback. That is normal! Can you imagine if everyone here on earth will say good positive about you? Well! that's impossible. That is why it's called " Feedback" which means prepare for both, negative and positive. After you ask around, the decision is yours to make. It doesn't matter what they say, but in the end it's in your hands to express what you want to write.
