That was the beginning of my journey toward understanding the complexity of audio work and, more specifically, about the role of mastering in the recording process. Having performed music live for years and having dabbled in the studio, I understood that both used mixing; but I had never heard of mastering. How is it different than mixing? Why is it needed? Why didn’t my mixing engineer just do that work for us? I went looking for the answers.
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.
