Hey all,
in the Internal Reference it says in
http://lilypond.org/doc/v2.15/Documentation/internals/tunable-context-properties:
middleCClefPosition (number)
The position of the middle C, as determined only by the clef. This can be
calculated by looking at clefPosition and clefGlyph.
Shouldn't it rather say:
middleCClefPosition (number)
The position of the middle C, measured in half staff spaces from the center of
the staff.
Here comes a Scheme snippet:
(make-music
'SequentialMusic
'elements
(list (make-music
'PropertySet
'value
"clefs.G"
'symbol
'clefGlyph)
(make-music
'PropertySet
'value
-6
'symbol
'middleCClefPosition)
(make-music
'PropertySet
'value
-2
'symbol
'clefPosition)
(make-music
'PropertySet
'value
0
'symbol
'clefOctavation)
(make-music
'ApplyContext
'procedure
ly:set-middle-C!))))
The position of the clef is two half spaces (-2) below the center of the staff.
The position of the middle C is 6 half spaces below the center of the staff. I
looked at various clefs (treble, alto, tenor, bass) and middleCClefposition is
always determined by the number of half staff spaces from the center of the
staff. It never refers to the position of the clef. But then I'd say
middleCClefposition is a misnomer and should rather be called middleCPosition.
Unfortunately middleCPosition already exists. What's the difference? Am I
barking up the wrong tree?
