In songwriting, there’s something called form. This is basically just the structure of your song, the order in which the sections happen and then when they’re repeated.
Here are a few songwriting structures to get you started – these are the most common song forms in popular music:
Verse – Chorus – Verse – Chorus – Bridge – Chorus
This is the most common chord progression in pop music. Turn on the radio and most songs will have this structure.
Verse – Pre-chorus – Chorus – Verse – Pre-chorus – Chorus – Bridge – Chorus
This is simply a variation on the first song structure, so it’s also common to hear this in pop music.
Verse – Refrain – Verse – Refrain – Bridge – Refrain
A Refrain is basically a Hook AKA a one-liner that is usually also the title of the song. This is a more common song structure in singer-songwriter music. It lends itself nicely to story-driven songs.
