It’s worth investing time developing a melody that allows your lyrical idea to fully register with the audience. So how do you write a tune that folks can remember irrespective of the lyrics? One that you can play as well as sing, one that is immediately recognizable covered by any one of a glockenspiel band, a choir, a bagpipe, or a thumb piano?
It’s amazing how you can play something perfectly 20 times in a row and then the moment someone switches on a mic, it all goes down the drain. One of the ways we dealt with this was by taking particularly challenging parts of songs and either breaking them into multiple tracks or separating them out and then re-splicing them together after. It takes all the pressure off getting one perfect take, start to finish.
