I was thinking back to a time, many years ago, when I was in college. I was talking with some friends about songwriting, and I mentioned that I often write the bass line before anything else in my songs. A female friend chimed in, "You have to write the lyrics and melody first, then use the melody to build the chords, then use the root notes of the chords to make the bass line. The bass line always comes last!" Not that there's anything wrong with starting with the lyrics and melody, but I couldn't believe that anyone, especially so young, would be so rigid about creativity. How often do you songwriting TBers build songs around a bass line? Or is that your standard songwriting practice?
