RE: Clarifying otave check (\octave) in Section 6.2.2

[Anthony Youngman]

C below middle C is just c all by itself so the syntax should be

a, b, c= d e f g a b

(rising steadily up the bass clef :-)

I remember using this test recently, and it does work. The problem I had
(Han-Wen sent me a fix) was that I needed the facility to force an
octave change, but I didn't want an error message that I knew all about.

Note that if you have any note durations it's  c=4.  - that threw me
initially and I was wondering why I couldn't get it to work.

Cheers,
Wol

Subject: Clarifying otave check (\octave) in Section 6.2.2

I am exploring the use of the feature described in section 6.2.2 of
checking that the notes are in the correct octave.

The manual says:

Octave checks make octave errors easier to correct: a note may be
followed by =quotes which
indicates what its absolute octave should be. In the following example,
\relative c'' { c='' b=' d,='' }
the d will generate a warning, because a d'' is expected (because b' to
d'' is only a third), but
a d' is found. In the output, the octave is corrected to be a d'' and
the next note is calculated
relative to d'' instead of d'.

Question

Specifing ' is fine for octaves above middle C, but specifying , for
octave below doesnt work.

Here is a test program:

\version "2.8.3"


\score {
    \new Staff << 
    \relative c''' {
       c b a g f e d
      % should now have reached the C above middle C
      
      c='' b a g f e d
      % should now have reached Middle C
      c=' b a g f e d
      % should now have reached the C below Middle C

      % Problem....how can I check if the next c is
      % The C one octave below middle C?
      
      c= b a g f e d

      c=, b a g f e d     % this doesnt work 

    }
    >>
    \layout { }
}


Error:

octavecheck.ly:20:6: warning: octave check failed; expected c', found:
c,
      
      c=, b a g f e d
