Sometimes when you don't plan it, a song is conceived. Maybe you hear a phrase someone says in a movie, or at church, or soaped on the back of a car, and you think, "Wow, that would make a great song!" You scribble it down on the nearest piece of paper, or sing it into your phone's recording device, or leave yourself a message on your answering machine: you can't forget how this little melodic and lyrical idea goes!
The pregnancy is the development of the song; what it will look like, how the verses will support the chorus, is the chorus universal enough that it can be sung over and over? Does the singer progress throughout the course of the song? Is the listener taken on a journey somewhere? How with this be conveyed musically? Fast? Slow? High? Low? Rocker? Ballad? Steak? Salad? (what?)
The labor starts when you get in the studio and have to make a final decision on how this song will be forever remembered! Pick the instruments and the people playing them. Choose a tempo and a key, decide when to come in and when to drop out, when to 'get big' and when to quiet down.
The Delivery is when a song has been completed and those closely involved in the entire process can listen to it and proudly announce, "It's a Song!" We marvel at what took so long to develop, and hold it high, sometimes a little too high, but most people are a little biased when it comes to being proud of their own! ;)
Then you leave the hospital and take the baby home, and there's a period of time where you have your new baby all to yourself. I've heard 4 of my new songs tonight completed for the first time, and I've probably listened to them a hundred times already (not really, but close) but they haven't been released to 'the world' yet.
Then the Presentation of the baby, whether it's that first Sunday back at church, or when everyone comes over to the house (because you let them). That's kinda like the Album Release. Now the world can look, and listen, and tell you what they think about whether or not they like your baby!
But those of you who are parents (of babies or songs) know that you can't help but love your own kids.
