Guitar chord exceptions would at least get the chords down to where they
sit nicely (around middle C), and would use inversions rather than try to
convey the bass note information in the chord itself (to me, C/E implies
some kind of bass instrument). That would be a good start.

In Europe's EURO zone (guessing from your name, that would likely be the
case) SEPA transfers are usually easiest (account number on request) as
the fees must not exceed in-country EUR transfers.  U.S. and U.K. and a
number of other countries get fewer fees via Paypal (this mail address
works fine).  However, I have to warn that I expect not to do a whole
lot for LilyPond in the next month or so.  I should have started
physical therapy this week but the respective clinic is booked out and I
enquired elsewhere.

The social worker dealing with my case is apparently spreading herself a
bit thin, so I need to improve my tactics.

In other news, I am currently doing my shopping/transportation basically
by foot which is taking its time but is safest for me and other traffic
parties.

And I'm having semi-permanent neck/head ache making focusing harder.
Control over my larynx is not exactly good: swallowing still
occasionally goes bad.  The right vocal fold is mostly paralyzed in
closed position yet and if it doesn't become accessible in a reasonable
amount of time, I'll probably eventually no longer be able to sing alto.
That's currently troubling me more than not being able to tell
heat/cold/pain on my left body side.

But even with some distractions being off-limits now, at the rate I am
being able to focus on complex tasks, I expect to be able to only
contribute lightly to LilyPond's progress in the next month or so.  Not
a whole lot of bang for the buck I am afraid.

At least apart from the head/neck ache and from the necessity for
physical exercise and keeping my blood pressure at tiresome levels, my
intelligence has not taken a hit: it's really mostly damaged wiring to
various body parts that I have to work with here.  But of course I need
to get the body back into a shape where I get along with moderate effort
in order not to take further hits to my bodily health.

In a nutshell: I'd appreciate support but it will be a bit of time
before I deliver good value for it again.

All the best

Re:Chords in LilyPond

[Peter Gentry]

Thanks to Carl and Kieren for explaining chord semantics.

 

A set of notes forming a chord  may have a different "meaning" depending on
the current key context.  Semantics seemed like a much grander idea to the
uninitiated.

 

However this idea would surely fall on stony ground in the context of atonal
or twelve note music.

Not really. In the musical theatre world, the symbol

   C4

is starting to be widely understood as  (with a C in the bass and no 5th 
in the chord), as distinct from

   Csus4

which is ; this parallels the use of C2 / Cadd2 / Csus2 as three 
different chords/voicings; but it’s also sometimes just written as

   F5/C

In the classical world, I’ve seen attempts to make (e.g.)

   CQ4

a standard way to notate

  

but I’ve never seen a real codified “system”.

Sorry I don’t have more concrete info for you. I would just love it if whatever 
chord name system(s) we build for Lilypond are flexible and forward-proof 
enough to support a quartal naming convention (as just one example), if one 
ever gets established.

Thanks,
Kieren.

Hi Carl,

I have seen an arrangement of a 1953 Miles Davis recording called 
"Enigma" (written by JJ Johnson) which contains such chords.
I guess there is no established symbol for these chords, but in that 
arrangement they were denoted "p4" as in Ab(p4). The p4 stands for - in 
my assumption - "perfect 4ths".


Best,
Robert

Just thinking out loud, but there's a fairly standard format for figured
bass, isn't there? If we've got chordmode and notemode, it wouldn't be
hard to add figuredbassmode, would it? That actually gives you quite a
lot of semantic information I think :-)

And it sets a bit of a precedent for "if you want a weird chord format,
define your own input/output mode" :-)

I imagine it would a bit, but not a lot.
My demands are not very sophisticated - normally for MIDI I transpose chords 
one octave down, set them piano and use an instrument that has not too much 
attack, like "fx 4 (atmosphere)".
Of course that doesn’t sound like guitar at all.
If I try to mimick my own picking, I don’t use the Chordmode voice in MIDI.
Maybe a library of picking styles would be possible on top of any internal 
representation of chords?

Happy that you're happy.

But the advantage of pdfcrop is that it works whereas -dpreview
doesn't. (There happens to be an active thread here on that matter¹.)

You also add a tool to your armoury that you can use on many
other² PDFs, LilyPond related or not, including ones that
you didn't produce yourself.

We are using semantics in the sense of “what does the chord mean?”. In a simple 
example, consider the chords

  

Is this a C major triad with added 6th, or an A minor 7th chord in first 
inversion? The notes in each are the same, but the meaning is different.

Hope that helps!

I had not heard of quartic chords before reading this email (as I've

study quartic chords.

But in my web search and following links, I never found anything that
approached a notation for quartic chords.  Their existence was discussed,
but I found no quartic-based notation; it was all just the notes.  Do you
have any source information that we could use to better understand quartic

This proposal for a chord ontology is one possible choice for assigning
semantics, although I don't like it at all.  As you say, it is very
technical, and doesn't really help with meaning, in my opinion.

> 
>Am I correct in seeing ³semantics² in this way ?

"Semantics" is a discussion of meaning.

https://www.merriam-webster.com/dictionary/semantics

"the meaning or relationship of meanings of a sign
 or set of signs;
especially : connotative
 meaning"

When we talk of "semantics", we talk of the meaning of the notes in the
chord.  At its most basic, a chord is a group of notes played
simultaneously.  In the context of western music, the notes in the chord
are selected to achieve a particular kind of harmonic progression.  We can
look at music theory and see that each chord has a particular reason for
being part of the music in relation to the preceding and succeeding
chords.  So for example see

https://en.wikipedia.org/wiki/Chord_progression


The aim of the Chords GSOC project is to try to capture the harmonic
meaning intended by the music, not just the notes.  And that's what is
meant by "semantics" in the context of this project.

HTH,

Carl

Re:Chords in LilyPond

[Peter Gentry]

I have been intrigued by the highly technical correspondence on this topic.
However I have struggled to understand what is being discussed.

A bit of googling has shed some light
http://debussy.music.ubc.ca/muset/guido/section3.html for instance but other
sources are even more technical. I was particularly thrown by the term
"semantics" this is a slippery customer that seems to mean different things
in different contexts.

In the link above it is simply a recipe for how to populate various
properties or parameters if not explicitly defined.

ie  Semantics: 

*   If size or style are not specified when using \noteFormat, their
current settings remain unaffected. If not modified using \noteFormat, the
default settings are size=1.0, style="standard".
*   The specified parameters are applied to all notes within the range
of \noteFormat, or, if no range is specified, until (i) the next \noteFormat
tag changing that parameter or (ii) the end of the current voice.

Other links such as http://motools.sourceforge.net/chord_draft_1/chord.html
describe in some detail the structure of chords beyond the simple C G7 etc
descriptions including where a strong note outside the "normal" chord
members is employed often by a solo instrument.

All this is way outside by musical knowledge whilst interesting it is
difficult to understand.

 

Am I correct in seeing "semantics" in this way ?

How about:

Hi Carl,

many thanks for your words about _what_ is tackled and what not. This
was not clear for me. I tried to reread the GSoC-projects-description
for this, but I couldn't find it...

There are still some details I'm not sure about. See below.

As an example:

\new ChordNames \chordmode { c:1.3.5 }

I wouldn't agree we currently throw away semantics about this c-major-chord.
We identify bass/inversion (none here) and keep them.
Afaik, we don't _use_ anything else from this user input, even the
root is determined in ignatzek-chord-names.

See above for root.

Do I understand correctly:
(1)
Problems with entering chords in note-mode is not really on the agenda
(in this case I'll not longer give such examples)
(2)
Finally something like the terminal-output of the fake below is aimed at:

chrd-test-III =
\chordmode {
\displayMusic
\withMusicProperty semantics
  #`((root . ,#{ c #})
 ;; or?
 (root . "C")
 (third . minor)
 (fifth . pure)
 (extensions . #f)
 (additions . #f)
 (bass . #f)
 (inversion . #f)
 (suspensions . #f)
 ;; else?
 )
c
}

<<
  \new ChordNames \chrd-test-III
  \new Staff \chrd-test-III
>>

-->
(make-music
  'EventChord
  'semantics
  (list (cons (quote root) (ly:make-pitch -1 0))
(cons (quote root) "C")
(cons (quote third) (quote minor))
(cons (quote fifth) (quote pure))
(cons (quote extensions) #f)
(cons (quote additions) #f)
(cons (quote bass) #f)
(cons (quote inversion) #f)
(cons (quote suspensions) #f))
  'elements
  (list (make-music
  'NoteEvent
  'pitch
  (ly:make-pitch 0 0)
  'duration
  (ly:make-duration 2))
(make-music
  'NoteEvent
  'pitch
  (ly:make-pitch 0 2)
  'duration
  (ly:make-duration 2))
(make-music
  'NoteEvent
  'pitch
  (ly:make-pitch 0 4)
  'duration
  (ly:make-duration 2

And let the printing function work on the 'semantics?

So far, best regards,
  Harm

I tried this:

$lilypond -dpreview  file.ly

And it worked: gave me "file.preview.pdf", that was auto-cropped. Idea
taken from here:
