Let's look at the beginning of the NR:
----
A pitch name is specified using lowercase letters a through g. An
ascending C-major scale is engraved with
\clef bass
c d e f g a b c'
----
If you can see the image, it's obvious which letter corresponds to
which note. We don't need to type "middle C is c'" or "octaves
start with c: "a b c' d' " is are four ascending notes.
Let's jump ahead to the Relative:
-----
A note sequence without a single octave mark can nevertheless span
large intervals:
\relative c {
c f b e a d g
}
----
Again, this is explained quite well if you look at the output.
We'd need a lot more explanation to make it understandable to
people who can't see the output.
Granted, pitches are explained with more text in the LM, so that
might not be such a big deal.
Taking my favorite "the docs suck" section, "falls and doits"
-----
Falls and doits can be added to notes using the \bendAfter
command,
\override Score.SpacingSpanner #'shortest-duration-space
= #3.0
c4-\bendAfter #+5
-----
This doesn't mean anything unless you can see the graphical
output. (granted, it doesn't help all that much if you _can_ see
the output... although a user familiar with this notation might be
able to figure it out)
I agree that lilypond could be great for blind users, but it
_would_ involve a lot of extra work on the docs. At the moment I
don't see enough volunteers to do this.
Sorry,
