Whenever I write a new song, the lyrics always seem to take the most time. Interestingly enough, the first thing I come up with is the title of the song. After I have the title, I start brain-dumping into my Google Docs document, just typing whatever lines fit that title. That title using comes from a whole bunch of thoughts that metaphorically relate to one another on the same topic...like details of a painting. After the brain dump of lyrics, I match them to a chord progression I've written in the past. One that fits the mood, and sometimes the mood AND the rhythm. Or, the lyrics inspire me to write a new guitar chord progression/riff. But, whenever all is said and done, I have to admit...sometimes I write the lyrics to a guitar part I have in mind. The freedom is never ending. That is when I start really getting picky with word choice, because I want to say a certain thing with each line, but making it fit the rhythm can be tricky...
