Re: \after syntax?
Thanks to all for the assist!
The new-coder mistake I had made was in mentally attaching the \after function
to the entire measure, instead of the note in question.
Best,
Matt

Hello all,
For hairpin positioning within a whole note, the Manual gives the syntax
\relative {
\after 2 \< c'1
}
Is there an effective \after syntax for hairpin positioning within NON-whole
notes, such as the second note in this (intuitive but) nonviable expression?
\relative {
\after 2 \< c'4 2.
}
CONTEXT: I need to place an \espressivo-shaped, double-hairpin swell underneath
a dotted half note. Also, I need it to be stretchable, so that I can
horizontally align it with the other, more active parts/staffs in my orchestral
score.
To emulate an \espressivo using actual dynamics by way of the \after function:
\version "2.25.13"
musA = \relative c' {
a'4 \after 8*3 \> a2.\< a2\! a2
}
musB = \relative c' {
a'4 \after 4. \> \after 2. \! a2.\< a2 a2
}
musC = \relative c' {
a'4 \after 4. \> a2.\< <>\! a2 a2
}
\score {
\new Staff {
\new Voice {
\musA
} } }
\score {
\new Staff {
\new Voice {
\musB
} } }
\score {
\new Staff {
\new Voice {
\musC
} } }
will produce:

Three different ways of accomplishing the same thing. The first showing that
you can indeed use scaling in the \after function (i.e. the 8*3 meaning 3 8th
notes worth) and terminating the decrescendo on the following note. The second
using \after to do the termination. The third uses the empty chord construct
(i.e. the <> ) to attach the termination to. You are, of course, free to mix
and match whichever method suits you.

If I interpret your nonviable snippet you want the hairpin to start halfway
through the measure and thus 1/3 into the dotted half note. Which means your
crescendo should apply to the c’2. rather than the c’4, which means the logical
snippet would be:
\relative {
c'4 \after 4 \< \after 2.\! 2.
% or
c'4 \after 4 \< 2. <>\!
}
Note: The explicit crescendo-end (either with another \after, or by an empty
chord is required in this small snippet as without it Lilypond complains
(warning) about an unterminated crescendo and completely omits the hairpin.
Depending on where the crescendo needs to end in your actual music you may or
may not need it, but for this snippet it is required to add.

Well, neither of those snippets compile without an error because the
hairpin is not terminated, but I don't see why you couldn't put the "after"
before the dotted half note and terminate it:
\relative {
c'4 \after 2 \< 2. c4\!
}
Am I missing what you're trying to accomplish?
