No I was going to define a bunch of chords in the init.scm myself and  
allow users to define them there also or in the script file itself. I  
wanted to put most the code in init. The script would only contain the  
list of chords wanting to test. It will contain chord definitions if  
the chord ls not in the init. What I think I need to use for it is a  
list or vector of pairs or a way to convert a string to a variable. So  
in schem,e if you have a string "Major", can it be tranlatrd or  
evauated like a variable. I think what I may need to do is make a pair  
like this:
(define Major (cons "Major" "c e g"))
(define Minor (cons "Minor" "c ees g"))

Then create a vector containg Major and Minor. The size of vector is  
fed to random. Car would then be the chord being played and cdr the  
untransposed spelling.
