This song is a great example of how music theory and psychology can help the songwriting process. In essence, you want to try to structure how listeners bring their sense of joy through the song, with the ultimate high point being in the chorus where lyrics and melodies are all repeated for better recall. Now you’ve got a tonal hierarchy to work with to make that section, and the others leading up to it, even stronger. I’ve learned this tip from experience. I’ve compared myself to other more successful (“better”) musicians and gone into a deep hole. The type of hole where I’m discouraged all day and don’t get very much done at all. So instead of wishing you had some other musician’s success or opportunities, put your blinders on and remember that you are you. Your story of success will look different than every other artist’s.
