First public release of GDP NR 2.7 Chord notation

[Carl D. Sorensen]

Dear LilyPond Users,

Notation Reference Section 2.7 Chord notation of the GDP has now been
released for public comment.  The HTML version of the document is available
at

<http://kainhofer.com/~lilypond/Documentation/user/lilypond/Chord-notation.h
tml#Chord-notation>.

Please take a few minutes to carefully review this section.  You may wish to
try out a few examples, if you've not spent significant time learning to use
\chordmode or you're unsure about chord naming conventions.  Please let me
know if you find anything that is unclear or incorrect.

The goal of the GDP is to make the quality of LilyPond's documentation match
the quality of LilyPond's output.  However, when I write documentation,
eventually I become blind to its weaknesses.  That's why it's so important
for the community to review the documentation.

Thanks in advance for your help.  Together, we can continue to improve
LilyPond.

Thanks,

Carl Sorensen
