My name gives it away...
It's funny how songs come - sometimes at the oddest moments. Once, I was in the shower, and I could hear the lyrics of this song, just flooding in my mind - with alternating lyrics for the lead and harmonies in the chorus, but it was all in rhythm - absolutely no melody. I sent that song to my friend in Oregon, who came up with the melodies in a matter of minutes (that was early on in my songwriting journey).
Last year, there were two songs that came, pretty much encapsulated - idea, lyrics - no melody. I was really busy with other work/projects, and had no mind to sit down at the piano and work them out. This year, after last year's projects were finished, I sat down one night, and finished both songs. One remained pretty much the same as what began last year, while the other completely transformed as the music came together. I ended up rewriting 60% of the lyrics, because of the feel, and cadence of the song.
Most of the time, though, the song begins as lyrics, and somewhere along the way, shortly after it begins, I hear the ghost of the melody. It comes to life when I sit at the piano, and try to re-create what I've been hearing, as the feeling of the words come together with the chords.
Does that make sense??
It seems most of you are musicians first, and wordsmiths second. I was a poet before I ever wrote a song, and long before I could play an instrument to go with what I wrote/felt. Maybe that is why lyrics come first for me.
