In what key

I've got this insanely personal project, www.inwhatkey.com. It's a website which contains some of the songs I play over when I improvise with my guitar. I never really found a way to properly find the keys of a song, so I made my personal library. I never really expected anything of it, but from Google Analytics, it turns out more people are looking for some of these songs!

I made a minor reference to playing cards since playing cards, to me, stand for both playful and calculated - which I think are two things you'll find are necessary to improvise over a song.

Anyway, I hope you'll like it. If you play the guitar and have requests, please let me know!
