I'm typesetting a piece which has an indication for gradual
opening/closing of a wa-wa mute. I've come up with a solution that I
think will work for changes that take up enough space but for short ones
my solution doesn't work. I've tried to address it like this:
%%%%%%%%
\version "2.11.54"
grad = {
\override Glissando #'bound-details #'right #'arrow = ##t
\override Glissando #'arrow-length = #1
\override Glissando #'arrow-width = #0.25
}
\relative c' {
\time 3/8
\clef "tenor"
<<
{
\grad
\hideNotes
g'16*5\glissando c16
\unHideNotes
}
\\
{
d,16^\open dis e f fis g^+
}
>>
\time 6/16
<<
{
\grad
\hideNotes
a16\glissando g
\unHideNotes
}
\\
{
es16[^+\f d^\open c] fis,[\< bes16^\open a]^+\!
}
>>
}
%%%%%%%%
In the first measure I'm pleased with the result. In the second
measure, the altered glissando graphic does not appear. I suppose
there's not enough room for it. The original manuscript does it with
hairpins:

I don't think it is necessary to duplicate exactly the original
notation. I don't really know how to make a hairpin behave like that.
Then again, maybe this would actually be more doable than my gliss/arrow
idea.
Ideas?
