Section 5.4.6 of the Notation RM states:
The to-barline property
The second
useful property of the spanner-interface is to-barline.
By default this is true, causing hairpins and other spanners which
are terminated on the first note of a measure to end instead on
the immediately preceding bar line. If set to false, the spanner
will extend beyond the bar line and end on the note itself
I have a
couple of questions about this section. The first is, why would
the default setting for to-barface be true? If I wanted my
spanner to end on the immediately preceding bar line, I could
easily set "\!" after the last note of the preceding bar.
The second
question has to do with the following two examples:
\version
"2.19.81"
{ \time 1/4
a8\> b
\override Hairpin.to-barline = ##f
c'4\! }
{ \time 1/4
a8\> b
\override Hairpin.to-barline = ##t
c'4\! }
Both
examples give identical output, i.e., the hairpin ends before the
first barline, not extending to the first note of the second bar
no matter what the setting of Hairpin.to-barline is.
How can I
extend the hairpin to the end of the note in the 2nd bar?
Please
answer both questions. Why would the default be so
counter-intuitive?
