With the songwriting process the hardest part is getting started. Where do you begin? The words or the music? The truth is either.
It is about the marriage of the two and how well you put those elements together.
If you start with the words the important first step is to Generate ideas. I am using the Generate, Sort, Connect and Elaborate principle.
The first step is identifying words that are associated with the subject.
The second step is identifying the important words.
The third step is connecting words that fit together. Either by the subject matter or rhyme scheme, alliteration etc.
The forth step is connecting the words and finding hook lines. Lines that really resonate with the meaning of the song.
Finally is to elaborate. Putting the words together with the music or forming a structure with the words such as Verse, Chorus, Verse 2, Middle 8, Bridge etc.
