For writing your own song, you’ll need to write the music score and the lyrics. You’ll need to be familiar with an instrument that can carry a melody (such as the piano or a guitar) and the methodology for songwriting for that instrument. You can learn to write lyrics yourself or if you need help with writing both melody and lyrics, see How to Write a Song with Music and Lyrics . The steps above will walk you through what's needed to write your own song successfully.
