Having looked some more at the documentation and code, I now realise that the gray shading indicates various trills. There are many possibilities, but one to indicate just a partially covered hole displayed in black seems to be missing. I suggest allowing the notation e.g. "one1hF" to indicate a half covered filled hole. It is currently not valid. This would need a change to `make-symbol-alist` in define-woodwind-diagrams.scm. My Scheme-fu is currently not sufficient to make that change, but I suppose I could figure it out eventually.

Why not just use "one" to indicate a half-covered hole?  Since there is no graphical difference between a half-filled hole and a filled hole, it seems like there does not need to be a separate notation for the half-filled whole in the input.

 

Sure there is a difference, see http://lilypond.org/doc/v2.19/Documentation/notation/woodwind-diagrams for "one1qT3q" for instance. Using "one 1h" as of now, the hole is displayed half covered gray. I'd like some way to display it half covered black without breaking existing usage.

 

Oh, I misunderstood what you wanted.  I thought you wanted to have a black filled hole, not a black half-filled hole.  

 

One way to do this would be to develop a new notation, as you suggest.   I would suggest that a notation of one1hB would be better than one1hF, because both the default half-covered diagram and the new half-covered diagram are half-filled; the difference is the color.

 

Another way would be to have a property that defines the fill color.  The default value for the property would be gray, but it could be set to black.  Or potentially any other color that was wanted (say red, or green, or yellow).

 

Thanks,
