Lilyjazz from a blind user

[Daniel Contreras]

Hello everyone,
I am attempting to use lilypond to write jazz charts for a small jazz combo, 
and possibly a jazz trombone ensemble. I downloaded and installed the lilyjazz 
fonts from fonts.openlilylib.org. My question is pertaining to the sample PDF 
documents that came with the zip file. Is there a way I could get the lilypond 
source files that these documents derived from? If that is not available, I 
really just want to know the proper way of notating cords/changes. I read the 
section in the notation reference about court names, however, how does one for 
example write "A13 sharp 11"?  Sorry for the long post, thank you for any 
answers that would point me in the right direction.
