Why? \set Score.voltaSpannerDuration = #(ly:make-moment 4/4)
still works.

No, I didn't. Frankly, I had no idea that something like that would be 
necessary.

\shapeII currently requires it (though I hope one day, \shapeII or similar is 
built in to the main distribution of Lilypond).


Unfortunately, that’s a long way still, since there are grave issues 
with \shapeII (see the openlilylib issue tracker). On one hand, I 
imagine that building it in the LilyPond core (C++ slur code !) would be 
a route to solve them, but that’s also a quite advanced task, it would 
seem. Though I agree that much would be gained!


Best, Simon

Re: Why warning: cannot end volta spanner?

[Peter Toye]

Mark and Kieren,

Of course! The reason I didn't spot it is that the alternative starts with a 
16-bar section in a \repeat unfold 2, and that of course is a separate 
expression. It looks like I'll have to do the unfolding manually - what a pain!

I am trying to do a similar thing with a volta repeat: a longish 1st time 
section without a long 2nd time volta indication. I tried to set the 
voltaSpannerDuration but this gives an error "cannot end volta spanner", which 
I don't understand. Is there a way of doing this without getting an error? It 
seems that LP tries to put the same number of bards into the 2nd time as the 
1st time. A quick straw poll of printed music implies that the norm for the 
final alternative is a single bar. Is this a bug or am I missing something?

Thank you for the MWE. If you want to show the second alternate bracket
over the "g" instead of "g a b c", then why not just move the "a b c" out
altogether? Then the \set Score.voltaSpannerDuration part isn't necessary
at all:

\version "2.18.2"

\language "english"

\score {
 \new Staff {

   \time 4/4
   \clef treble

   \relative c''
   {
 c1
 \repeat volta 2 {
   c d e f
 }
 \alternative {
   {
 g f e d
   }
   {
 g  %<-- JUST THIS HERE
   }
 }
 a b c  %<-- THE REST HERE
 b a g
   }
 }
}

HTH,
Abraham

Re: sustain pedal

[Kieren MacMillan]

Hi Daniel,

I would suggest using a second/hidden voice with skips for the pedalling 
instructions:

\version "2.18.2"

\paper { ragged-right = ##f }

\relative c {
  \set Staff.pedalSustainStyle = #'mixed
  \time 6/8
  \clef bass
  <<
2.\fermata
\new Voice { s4\sustainOn s\sustainOff\sustainOn s\sustainOff }
  >>
}

Hope this helps!
Kieren.

Hi Daniel,

Please see: http://lilypond.org/tiny-examples.html

How about:

\relative c {
  \time 6/8
  \clef bass
  2.\fermata
  -\tweak X-offset #-2
  -\tweak X-extent #'(0 . 0)

Yes — that’s the key. And the reason for the empty measure.

Re: Ties, distance from barline at a system break

[Andrew Bernard]

Hi Robert,

As I briefly mentioned \shapeII is in the openlilylib project. It's a
generalisation of the builtin \shape. The openlilylib directory containing
that is called 'notation-snippets/shaping-bezier-curves'. There is a well
written paper there on how to use it with good examples.

Hi Kieren,

No, I didn't. Frankly, I had no idea that something like that would be 
necessary. 
There was no separate log-file but I copied he text from the console (I use 
TeXShop as the LilyPond editor) and pasted it in the Post Script of this mail. 
It speaks of a fatal error but nevertheless generates a nice pdf (with no 
improvement of the tie-distances of course). But I should have noticed the 
error warnings like " error: unknown escaped string: `\shapeII' " etc.

Anyway, I will follow your advice and download and install  the openlilylib

It is terra incognita for me but I'll have a go at it and if and when I get 
stuck I will scream for some more help.

Thanks for your help.
