customising chords

[Bailey James E.]

I don't know if 2.7.2 on customising chords has been rewritten yet,  
but I'm having a difficult time understand how to customize chord names.

First, to be absolutely clear, this is the first time I'm using  
\chords. Second, I've be reading and re-reading this section for about  
10 minutes, and I think I've spent too much time on it. Third, all I  
really want is F4 and F3. Right now, my solution is to write F7 and  
modify the 7 to show what I want. I'm sure there's probably a better  
way.

Is it just me, or is there no example in customizing chord names. I  
mean specifically, if I wanted to use \italianChords, where does it  
go? Second, the section on chordNameExceptions, which is probably what  
I need uses Scheme to set it, and I have zero understanding of scheme.  
(I'll admit it, I really don't care to learn Scheme, learning lilypond  
is enough for me.) Does that mean that chordNameExceptions can only be  
used with scheme? Because I don't understand a single word of those  
two lines of scheme code.

Incidentally, I'm able to get the output that I have because there's  
an example of how to use majorSevenSymbol, and it doesn't use Scheme.

So, to anyone who knows a bit more about chords than I do: help, please?
