A few thoughts on the subject of Formulas in songwriting
1. Formulas are used when a person wants to duplicate an action or event, or to describe analytically an action or event. No metion here about creativity. I love Neil Diamond's music, but there are many examples of "formula writing" in his catalog. Also check out the Monkeys songs, (Boyce and Hart), there is a strong link between the songs for a number of reasons, suffice it to say that they were all reading the same book on formula songwriting.
2. It is good to analyze succesful songs melodically, harmonically, lyricly, rhythically, structurally etc, but then we hope to pass thru with a deeper understanding of those aspects of songwriting. If we stop there and say that we know how to write, we sell out our own creativity. All we are is historians. The best of us will go on to evolve into our own identity as an artist/writer with a unique world view and set of attitudes.The 'tudes are critical cause nobody cares what happens in a song, only how we feel about it.
