Do you have a two-minute number that somehow feels like it’s dragging on without going anywhere? Maybe you need to add a bridge. Does the move from your verse to your chorus feel overly sudden, leaving things disjointed? Consider using a pre-chorus to ease that transition. Do you want a place for the audience to clap along? Sometimes doubling up the last chorus can accomplish that nicely.
“Sunflower”: Sneaking into the last week of Top 5s for 2018, we have a consummate “B-side” to the other Post Malone songs on this list, with a short and sweet form — except for the fact that each singer’s verses use different melodies and lengths. And since we’re talking about lengths, the loop here is eight bars long, not your usual four. This makes it easy to chop in half for the shorter second verse, as well as the shortened outro.
