Re: Analysis brackets

[Michael Taylor]

Many thanks for this. I need to experiment a little to see if I can fit the
brackets into a rather congested setting.
With best wishes, MT

Re: Analysis brackets

[Kevin Barry]

Hi Michael,

Below is some code that replaces a horizontal bracket with a curly
brace of the same width. The math is the result of experimentation,
but it seems to hold up to changes in staff size and for medium-sized
groupings of notes.

\version "2.19.84"

#(define curly-analysis-brace
   (lambda (bracket)
 (let* ((bracket-width (interval-length
(ly:stencil-extent
(ly:horizontal-bracket::print bracket) X)))
(bracket-dir (ly:grob-property bracket 'direction))
(bracket-layout (ly:grob-layout bracket))
(output-scale
 (/ (ly:output-def-lookup bracket-layout 'output-scale)
1.75729901757299))
(brace-rotation (if (eq? bracket-dir DOWN) 90 270))
(brace-size (* 5 bracket-width output-scale))
(y-scale (- 1 (* brace-size (/ brace-size 1.5) 0.04 (/
1 output-scale
(brace-offset (* (/ 1 output-scale)
(+ (* 0.2 output-scale) (* 0.103 brace-size
)
   (ly:grob-set-property! bracket 'text
 #{ \markup
\scale #`(1 . ,y-scale)
\translate #`(,brace-offset . 0)
\rotate #brace-rotation
\left-brace #brace-size #})
   (ly:grob-set-property! bracket 'stencil ly:text-interface::print)
   )))

% \startCurlyGroup is a convenience for doing just one curly analysis bracket
startCurlyGroup = \tweak after-line-breaking #curly-analysis-brace \startGroup

\score {
  \relative {
c''4\startGroup \startGroup \startGroup
d4\stopGroup
e4
d4
c d e d\stopGroup
c d e d\stopGroup
  }
  \layout {
\context {
  \Voice
  \consists "Horizontal_bracket_engraver"
  \override HorizontalBracket.after-line-breaking = #curly-analysis-brace
}
  }
}

Dear David,
Many thanks for this. I was curious about the curly analysis brackets when
I saw this in Snippets http://lsr.di.unimi.it/LSR/Search?q=curly but
couldn't figure out how (or if) these
shapes could be used for what I wanted. The only application I could find

Analysis brackets

[Michael Taylor]

Dear collective wisdom, in transcribing analytical markings I encountered a
curly horizontal bracket over a number of pitches. Is it possible to format
the existing analysis bracket to reproduce this, or are there other
solutions? Would it be possible in a future version to have the option of
placing text within analysis brackets as well as the default above? MT

A change was introduced after the docs were written: you have to write
\tweak HorizontalBracketText.text for this to work.

The snippet you're seeing was fixed, but scripts/auxiliar/makelsr.py
needs to be run for the changes to show up in the documentation.




Ah, ok, now I see the parenthesized text!

\layout {

The first \stopGroup closes the smaller grouping, because the system is
designed so that brackets nest cleanly.

Interestingly, this overlap is possible with slurs:

%

\version "2.19.25"

secondSlur = #(make-music 'SlurEvent 'span-direction START 'spanner-id "2")
secondEnd = #(make-music 'SlurEvent 'span-direction STOP 'spanner-id "2")

\relative c'' {
  c( d c\secondSlur d) c d\secondEnd
}

%%

This, too:



thirdSlur = #(make-music 'SlurEvent 'span-direction START 'spanner-id "3")
thirdEnd = #(make-music 'SlurEvent 'span-direction STOP 'spanner-id "3")

\relative c'' {
  c-\tweak Slur.positions #'(4 . 4) ( \secondSlur
  c\secondEnd\secondSlur -\tweak Slur.positions #'(3 . 3)\thirdSlur
  c\secondEnd\secondSlur
  c)\secondEnd\thirdEnd
  c( d c\secondSlur d) c d\secondEnd
}

%%%

Maybe a system could be devised where brackets nest by default, but a
spanner-id property can be used to create more sophisticated structures?

Which of course makes them unsuitable for showing phrase elision.

Getting a TextSpanner to begin on a note and another to start on the same
note requires some sleight-of-hand (you can see this in Scheme in the

Hi David,On Aug 30, 2015, at 3:16 PM, David Nalesnik david.nales...@gmail.com wrote:LilyPond already has the ability to make analysis brackets, which are attached to note columns and can nest as in the link (HorizontalBracket). I have an old patch for adding text to these that I will finish up and post. (I have code for doing this in Scheme, but my approach now is an enhancement of the C++ engraver.)The attached file is what I used to use when making form handouts.This is great! – both the analysis brackets (which I didn’t know about before) and your code for text labels for them.

Good catch.  Thanks!

Actually, you can.  The syntax is just a little awkward, though:

 gluck = \relative c'' {
  \time 3/4
  \key f \major
  \override HorizontalBracket.direction = #UP
  c4-\tweak stencil #(label #{ \markup \italic \center-column {
contrasting period } #}
   #{ \markup \italic \center-column { period
(cont.) } #})
  \startGroup
  -\tweak stencil #(label a a )\startGroup
  a8( bes c f)
  f4( e d)
  c d8( c bes c)
  \appoggiatura bes4 a2 g4 \stopGroup
  %\break
  f'8-\tweak stencil #(label b b)\startGroup r a, r d r
  c4( e, f)
  g8( bes) a4 g8( f)
  f2 \stopGroup \stopGroup r4
}

%%%

The plan at the moment is to create a grob HorizontalBracketText.  That
will allow easy use of markups through overrides of a 'text property:

\override HorizontalBracketText.text = \markup ...

and tweakability.

Best,
David

Re: Analysis brackets with text [was: how to get notes without tails?]

[Paul Morris]

Oh, one other thing I noticed.  There seems to be no way to have one bracket 
end at a note and another bracket start at that same note. (warning: 
conflicting note group events”)  I tried spacer rests, but no luck.  It seems 
the start or end of a group cannot be a spacer rest.  Anyway, I thought I'd 
mention this, FWIW.

Hi David,

That’s great that markups already work (I should have tried it before assuming 
they didn’t).  The plan for HorizontalBracketText sounds even better.

My go-to solution (which is hackish) has been to create a tuplet over spacer 
rests and change the tuplet number text.

Hello there,

Thank you very much for your time and for your nice  prompt solution which
solved the problem. 

Eluze wrote

Yes, in fact I made a mistake in chord notation, and following your advice I
replaced ,  respectively by  and  for each chord and then I was able
to use brackets on chords without problem.

Exactly, this is what I was looking for, \markup allows to add short
comments on brackets. So here is what I added at the end of \stopGroup for
each bracket \stopGroup_\markup{\halign #3 \typewriter{P3}}

Thanks for your time  for your help

Kind Regards
Dariyoosh

Question about the use of analysis-brackets by using \startGroup and \stopGroup

[dariyoosh]

Hi,

*Environment description:*
OS: Fedora Core 17 X86_64
Lilypond version: 2.16.0

*Problem description:*
I was searching the online Lilypond notation guide, in order to see how to
use horizontal brackets in order to group several notes (possibly from
different bars). Based on what I found in the following link

http://www.lilypond.org/doc/v2.16/Documentation/notation-big-page.html#analysis-brackets
http://www.lilypond.org/doc/v2.16/Documentation/notation-big-page.html#analysis-brackets
  

Here is what I implemented:

If you run the above code, you can see that in fact two brackets are added
and this is almost what I'm looking for. However I didn't manage to use
*\startGroup* and *\stopGroup* within chords. For example the following
example fails:


As a result, I would like to ask two questions:

1) How should I modify the above code in order to be able to use
analysis-brackets also for chords (if it is possible)?
2) Is there a way to add a comment (for example writing P1, P2 for meaning
respectively part1 and part2) above the bracket?

Thanks in advance,

Kind Regards,
Dariyoosh

text on analysis brackets

[David Nalesnik]

Hi, all --

I'd like to be able to add text to analysis brackets, and I'm running
into a problem with nested brackets.

In the attached file, I'd like the last bracket to have b over it,
but it takes its text from the previous incomplete bracket.

(It seems I can add as many nested brackets as I like with different
text, as long as they have the same starting-point.)

Is there anything I can do to make this approach work?

Best,
David

\override  HorizontalBracket #'direction = #UP
\override  NoteColumn #'ignore-collision = ##t
\hideNotes
e''4-\tweak #'stencil #(label b)\startGroup

  }


So to refine the original question: Is there any way to do this
without multi-voice trickery?

Analysis brackets?

Hi, I need to draw several superimposed -- although not nested -- 
brackets in order to evidence two 
melodic overlapping structures for teaching purposes. Does 
anyone knows how to do it?

I've tried Analysis brackets but the groupings are presumed nested 
and so, the group openings and 
closings are interpreted as in a heap.

I'm looking for something like:
\openGroup1 c d e f \openGroup2 g a b c \closeGroup1 d e fis g \closeGroup2


Thanks!

As the Horizontal_bracket_engraver lives at voice level, overlapping 
brackets need to live in different voices.


\version 2.12.2

upper = \relative c'' {
 c\startGroup d e s4
 g a b c\stopGroup
 d e fis s4
}

lower = \relative c'' {
 s2. f4\startGroup
 s1
 s2. g'4\stopGroup
}

\score {
 \new Staff {
   
 \voiceOne \upper
 \voiceThree \lower
   
 }
}

\layout {
 \context {
   \Voice
   \consists Horizontal_bracket_engraver
 }
}


Btw, you can put any bracket above the staff with \once \override 
HorizontalBracket #'direction = #UP

Analysis brackets for lyrics

[Matthieu Jacquot]

Hi all,
I try to use analysis brackets in a lyrics context, the problem seems more
global : how to call a function in a lyrics context? In the code below the
second staff is when bracket is linked to notes, it would be fine if it was
below the lyrics text. Can anybody help me? Thanks in advance.
Matth
So here's the code :

\version 2.11.*
 \new Voice { c'4 c' c' c'}
\new Lyrics \with {\consists Horizontal_bracket_engraver} 
\lyricmode
{a \startGroup a a a \stopGroup }
  

 \new Voice\with {\consists Horizontal_bracket_engraver} { c'4
\startGroup c' c' c'\stopGroup }
\new Lyrics \lyricmode
{a a a a}

Re: Analysis brackets for lyrics

[Matthieu Jacquot]

Ok, I reply to myself.
I was hesitant to use the extra-offset command because I though that it
would generate a lot of collisions but as it seems that the lyrics and the
brackets are attached to the same objects (notes) they move together, great!
a sample code for those who would be interested :

 \new Voice\with {\consists Horizontal_bracket_engraver} {
\override HorizontalBracket #'extra-offset = #'(0 . -4)
 c'4 \startGroup c c, c'\stopGroup }
\new Lyrics \lyricmode
{a a a a}

Analysis Brackets with dashed lines

[Hugo Ribeiro]

Thanks all who helped me. This is the example of a Bach Invention 
analysed by Kent Kennan. For the brackets I used:


\startGroup \endGroup as normal brackets.
\[ \] as dashed lines in the up part of the staff
\startTextSpan \stopTextSpan as dashed lines in the bottom of the staff

I also copied the arrows from the Flamenco template and used as a markup 
in the lyrics context and in some notes.


I am attaching because it may be of some use for someone in the future...

Single note analysis brackets?

[Hugo Flordal]

I'd like to use the Horizontal_bracket_engraver to indicate single notes, but it
seems analysis brackets can only be used over multiple notes. I'm attempting to
write 
  c8\startGroup\stopGroup
but this isn't working. Is it possible to get around this somehow? Perhaps by
adding a dummy note with zero width somewhere? All my experiments and solution
searches have failed...
  I also tried using the Ligature_bracket_engraver, but it does not appear to be
very stable and I can't find a way of tweaking it into producing horizontal
brackets at a fixed height.

It would be nice if analysis brackets could be generalised so that they could
replace the Ligature_bracket_engraver completely... (And perhaps use the \[ \]
notation as well...)

Hi Matt,

Actually, you can stick an override in the note entry of the music
itself if you want to.

In fact, there are three override locations. All three override
locations are equivalent:

1. In a \context block (which lives within the a \layout block)
2. In a \with block (which follows context instantiation immediately)
3. In the note entry of the actual music


1. Here's an override in a \context block, as before:

\score {
  \relative c'' {
c4\startGroup\startGroup
c4\stopGroup
c4\startGroup
c4\stopGroup\stopGroup
  }
  \layout {
\context {
  \Staff \consists Horizontal_bracket_engraver
  \override HorizontalBracket #'direction = #up
}}}


2. Here's an override in a \with block:

\score {
  \new Staff \with {
 \consists Horizontal_bracket_engraver
 \override HorizontalBracket #'direction = #up
   } {
 \relative c'' {
c4\startGroup\startGroup
c4\stopGroup
c4\startGroup
c4\stopGroup\stopGroup
  }
  }
}


3. And here's an override in the note entry of the music itself:

\score {
  \new Staff \with {
 \consists Horizontal_bracket_engraver
  } {
 \override Staff.HorizontalBracket #'direction = #up
 \relative c'' {
c4\startGroup\startGroup
c4\stopGroup
c4\startGroup
c4\stopGroup\stopGroup
  }
  }
}


Gurus, are there any other override locations? Or just these three?

Use whichever override location you prefer. (I prefer method #2 with a
\with block, because this leaves context settings with the context and
layout settings in \layout. Other users prefer other override
locations as a matter of style.)

No matter which override location you pick, you *must* first determine
the context of the grob you wish to override. In this case the
HorizontalBracket grob lives in the Staff context. You absolutely have
to determine this; otherwise you might write something like \override
Voice.HorizontalBracket #'direction = #up, which is absolutely correct
syntactically but will have no effect whatsoever because you've
misspecified the context.

Well, you could also use \tweak and you have two variations of
alternative 1. - placing the \layout block outside or inside the \score
(hmm, if you have a \book block in your file, then you have three
possible levels for your \layout block).
Matthew, don't worry if you don't follow all the details here.

 Hi Matt,

 Actually, you can stick an override in the note entry of the music
 itself if you want to.

 In fact, there are three override locations. All three override
 locations are equivalent:

 1. In a \context block (which lives within the a \layout block)
 2. In a \with block (which follows context instantiation immediately)
 3. In the note entry of the actual music


 1. Here's an override in a \context block, as before:

 \score {
   \relative c'' {
 c4\startGroup\startGroup
 c4\stopGroup
 c4\startGroup
 c4\stopGroup\stopGroup
   }
   \layout {
 \context {
   \Staff \consists Horizontal_bracket_engraver
   \override HorizontalBracket #'direction = #up
 }}}


 2. Here's an override in a \with block:

 \score {
   \new Staff \with {
  \consists Horizontal_bracket_engraver
  \override HorizontalBracket #'direction = #up
} {
  \relative c'' {
 c4\startGroup\startGroup
 c4\stopGroup
 c4\startGroup
 c4\stopGroup\stopGroup
   }
   }
 }


 3. And here's an override in the note entry of the music itself:

 \score {
   \new Staff \with {
  \consists Horizontal_bracket_engraver
   } {
  \override Staff.HorizontalBracket #'direction = #up
  \relative c'' {
 c4\startGroup\startGroup
 c4\stopGroup
 c4\startGroup
 c4\stopGroup\stopGroup
   }
   }
 }


 Gurus, are there any other override locations? Or just these three?

Well, you could also use \tweak and you have two variations of
alternative 1. - placing the \layout block outside or inside the \score
(hmm, if you have a \book block in your file, then you have three
possible levels for your \layout block).
Matthew, don't worry if you don't follow all the details here.


WARNING: what follows is minutiae and not necessary for forming good \overrides.

Mats - I follow you on the \layout part; \layout blocks can go at any
of three levels: score-level, book-level or top-level. So that part
makes sense.

But how can you get \tweak to work for something like
HorizontalBracket? My understanding of \tweak comes down to one of two
different things: either for stuff connected directly to input (like
notes of a chord, as the docs say) or stuff that happens at the same
moment (which is my understanding, and useful for tweaking nested
tuplet brackets beginning at the same moment).

Could you shoot over a quick ex with \tweak for the HorizontalBracket
stuff that Matt was asking about?

Analysis brackets linebreaks

[Rutger]

Dear all, 

I'm considering using Lilypond for my musicology thesis, but I am still
learning it and there's one thing I still can't work around, which is the
following: 

- I'd like to use analysis brackets to indicate the form of a melody, but
the horizontal brackets created by \startGroup\stopGroup split into two
seperate brackets over a line break, but what I would prefer is one
half-bracket with an open (i.e. horizontal) ending and one half with an open
beginning (¬) at the next line. How can I solve this? I have noticed that
the example with the split ties under the 'difficult tweaks' section in the
manual (9.3.6), together with the edge-height property may offer a solution,
but I haven't been able to get this to work. (Actually, I am still hoping
that there may be a more smooth and elegant solution to my seemingly simple
problem, too...)
- Besides, is there a easy way to place letters just above these brackets
(to indicate phrases like A, B, A', etc)? 

Is there anone who can help me with this?
Many thanks in advance, 

Rutger Helmers


(P.S.: I hope you haven't received this message twice; my apologies in case

Colouring analysis brackets

[Édouard Gilbert]

Hi,

I'm not using Lilypond for a long time, so sorry if my question seems 
ridiculous.

I'm wondering if there is a way to print horizontal brackets in different 
colours
even when they start on the same note. Here come an example
(don't mind the notes or structure, they are nearly random).

%
\header
  {
title = Title
  }
  \score
  {
{
\once \override Staff.HorizontalBracket #'color = #red
d'\startGroup\startGroup\startGroup\startGroup\startGroup
d'\stopGroup ees'\startGroup e'\stopGroup\stopGroup e'\stopGroup
e'\stopGroup c'\startGroup\startGroup c'\startGroup\startGroup
c'\startGroup cis'\startGroup c'\stopGroup\stopGroup\stopGroup
c'\stopGroup\stopGroup g\startGroup a\startGroup
bes\stopGroup\stopGroup\stopGroup\stopGroup
   }
\layout
{
  \context
  {
\Staff \consists Horizontal_bracket_engraver
  }
}
  }

\version 2.8.5
%

As one can see, the five brackets opening on the first note are printed in red.
Is it possible to print, say, the second on in red, the fourth one in blue
and the others in black?

Thanks for your help,

Édouard

Analysis brackets start too early

Is this really how it's supposed to work? The below code puts a bracket over a b c and not only over b c as expected.

Remember that lilypond is almost all postfix notation.  :)
(think of the behavior of a slur or beams)

Re: Analysis brackets

[Mats Bengtsson]

If you check out Documentation - Program reference - Translation
- Contexts - ...
you will find out what engravers live in what contexts.
For example, you will find that the engravers for rests, note heads
and stems, for example, appear in the Voice context, not in the
Staff or RhythmicStaff.

Hello again,
So, my latest attempt to put proper analysis brackets underneath both 
staves is to use an extra invisible RhythmicStaff like this:

\context RhythmicStaff \with {

  \remove Time_signature_engraver
  \remove Rest_engraver

However, the \remove Rest_engraver seems to be having no effect. Nor 
does trying to remove note head and stem engravers when using notes 
instead of rests.

Could somebody please tell me what I'm doing wrong?
Also, even if it worked, this would definitely be a sub-optimal solution 
from a spacing point of view, so I'd still like to know if there's a 
better way (as I start to glimpse the power of tinkering with lower 
levels of lilypond, I think there must be!)

I would be most grateful for any response - I'd love to have more time 
to play, but I've got to hand in a dissertation (with this analysis in 
it)  in two week's time!

Re: Analysis brackets

The simple answer to your question seems to be to add the
engraver to the PianoStaff context instead of the Staff context:
\paper {
  linewidth = 413\pt
  indent = 0.0\mm
  raggedright = ##t
  #(paper-set-staff-size (* 18.0 pt))
  \context {
