Welcome to the world, my unbearably adorable, squishy, little coochie-baby song idea. Come with me immediately to the SongKindergarten(TM).
Actually, you are allowed to stay here forever. It's a free kind of school. No curriculum. No teachers. Play with other little darlings if you like. There are dozens of them! Go crazy. Let things happen. No worries.
Sometimes a SongExpresso inspector will arrive unannounced. Don't be afraid. Unless you are more or less identical to one of the other little i-dears, you'll never be ejected. Possibly you will be made to play with other similar ideas. Possibly you will get to come and dine with me, and get fattened up to make you bigger and stronger and more developed. Maybe even grafted together with one of your fellow little ones to form a bigger idea (child metaphor starting to run out of steam).
If SongExpresso sees that you are nearing adolescence, you may be thrust into the SongCollege(TM). This is good for you. You want this. The SongKindergarten is a great place to be but you should really be moving up in life and seeing something new. Here you will get my full attention. There are probably not more than 10 or 15 other spotty young things in this class. You may even get introduced to a collaborator and move in a different direction. Certainly here you'll get lots of instrument time and this is where you really grow into your full potential. Unlike mammals, it's not at birth but here where the "labour" really happens (child metaphor starting to get quite weird now).
You're an adolescent. You're unruly. You have some bits that are messy and some that no-one really understands. You have some bad rhymes still and some outlandish images. You have 4 and a half verses, which is about 50% too many but no-one is sure which are the good ones. You lack a break or a solo or an intro. But you're the future. You'll work your way into my brain and during the night or the shower or a book or being out in the park, a little bit more of you will be finished off.
Until the day where we all smile. You're good to go. You're a SongGraduate(TM) - you can now officially use the title "Song" (or any of its translations in any official language of your choosing). You can go out into the world and see whether someone other than your proud parent will love you. It doesn't matter, because I always will.
Maybe you're an ant-idea and will progress through all stages in a day. Or maybe you're more of a diplodocus-idea and will have the longest adolescence of any living thing ever (please do not write in to tell me that this is not a scientific fact and it should be e.g. the Royal or Wandering Albatross). The important thing is to keep moving. Because there are lots more cute little coochie babies being born every day.
A broody SongExpresso is off to re-name his "Song Ideas", "Songs in Progress" and "Songs Finished" Evernote notebooks. What do you call yours?
