Re: Chord names below staff?

[Trevor Daniels]

Hi Luc

This example illustrates the difference between introducing chords with 
\chords and \chordmode.  \chordmode simply interprets the following input as 
chords;
\chords does the same but also creates an implicit ChordNames context.  In 
your example I think the \context ChordNames command in the score does not 
create a new context as expected because one has already been created by the 
\chords command.  (It would be better if LilyPond then placed it in the 
staff structure as specified in the \score block, but it appears it does 
not.)

There are at least two ways to avoid this confusion and get the structure 
you expect.  You can move the override(s) into the harmonies variable and 
remove the ChordNames contexts, like this:

melody= { a 1  b c }
harmonies= \chords {
 \set chordChanges = ##t
 a1 b c
}
\score {
  <<
    \harmonies
    \new Staff = one \melody
    \harmonies
  >>
}

or you can use \chordmode and create the contexts explicitly with \new as 
below.  I prefer this as I like to keep all the structure stuff explicitly 
in the \score block and the music in variables, to avoid surprises like 
this.  I think this is clearer:

melody= { a 1  b c }
harmonies= \chordmode {
 \set chordChanges = ##t
 a1 b c
}
\score {
  <<
    \new ChordNames \harmonies
    \new Staff      \melody
    \new ChordNames \harmonies
  >>
}
