“The best way to get a good idea is to get a lot of ideas.”
– Linus Carl Pauling (1901-1994)
Linus Pauling was an American quantum chemist and biochemist. He was also acknowledged as a crystallographer, molecular biologist, and medical researcher.
Transpose that quote by Pauling from creativity in general to music specifically, and you can easily say: the best way to come up with a good song is to come up with a lot of songs, most of which will be crap.
And maybe somewhere in that pile of creative dung is something that sounds like a gem, a dancing star, or the nugget of an operatic anthem that just might rock the cosmos.
People on the ElectronicaManila mailing list sometimes ask me about my music creation process and they ask how many tunes it takes to play live. I answer: all it takes is one tune, and the desire to play it live.
Doesn’t mean you’ll sound great though, because until you’ve made a mountain of tunes, most of which will be crap as I said, you’ll never wade to the other side with that handful of 5 or 7 or 10 fantastic compositions that are in you.
You simply have to trust in your ability to improve your craft.
I think it was Julia Cameron who wrote: take care of the quantity, and let God handle the quality.
