Cool site...worth a bookmark.Musical shorthand is a good idea. But it's a problem for a doofus like me who's not so familiar with the scales to know that a "6" in the key of Eb is....ummm, let's see,Eb,F,G,Ab... ummmm....oh yeah, C (Cm according to the Nashville Number system). I use a similar 'cheat sheet' except I just write out the chord:
||Asus2-C#m :||
|_____4______|
Or something like that. I'd still like to know what Rick said about it.
