Balancing the Three Key Elements of Story

I was talking with a songwriter friend this weekend about how his songs are put together.  An idea usually comes--about a person, a place he visited, or an experience he had.  He then begins to brainstorm ideas for the lyrics (some songwriters start with melody, but he goes forward from the lyrics).  They start telling a story, using his initial idea. 

If he begins with a person--say, he's writing a love song or a song about heartbreak--he knows eventually he'll also bring in details about where and when, as well as what happened. 

He says that there's a cool alchemy that happens when all three of these elements are in place.  They create synergy with each other.

If he leaves one out, the song just doesn't feel complete.
