Creativity

I have this book on creativity, by an artist or art teacher, you probably know what I'm talking about, that   claims the right side of the brain is more creative, since this is the visual side. Of course, this kind of crude bicameralism is scientifically incorrect. Not only that, why does only the visual get to be creative? Why not the musical and verbal?  I feel as creative when I am noodling as when I am doodling.  Even more so, since my songs are better than my drawings. I don't even try to write new songs now. I just play and once in a while something will occur to me and I will develop it into a song.

I think I need to do more song settings.  Maybe Herrick?  

I am sure that there are uncreative artists, just as there are uncreative creative writers.

Also, once creativity becomes the province of corporate culture, won't it lose any value?
