Hi Tom,
Building upon the code from scm/chord-name.scm (and related files) as
well as (LSR #750)[1], here is a more complete version of the
interval-based chord root namer:
[1]:http://lsr.di.unimi.it/LSR/Item?id=750
```lilypond
\version "2.18.2"
#(define (intervalic-namer pitch lowercase?)
(let ((handle-case (if lowercase? string-downcase (lambda (x) x)))
(alt (ly:pitch-alteration pitch)))
(make-line-markup (list
(make-simple-markup (handle-case
(vector-ref #("I" "II" "III" "IV" "V" "VI" "VII")
(ly:pitch-notename pitch
(if (= 0 alt) empty-markup
(alteration->text-accidental-markup alt))
#(define (intervalic-namer-custom-alts pitch lowercase?)
(let ((handle-case (if lowercase? string-downcase (lambda (x) x)))
(alt (ly:pitch-alteration pitch))
(custom-alts `((,FLAT . "b") (,SHARP . "#"
(make-line-markup (list
(make-simple-markup (handle-case
(vector-ref #("I" "II" "III" "IV" "V" "VI" "VII")
(ly:pitch-notename pitch
(if (= 0 alt) empty-markup
(make-small-markup (make-raise-markup 0.7 (make-text-markup
(ly:assoc-get alt custom-alts "?")
theChords = \chordmode { c8 d/fis e:m7 f:maj7 g:7 a:m bes:sus4 b:dim
}
\score { << \new ChordNames \chordmode {
\omit Score.BarNumber
\override Score.RehearsalMark.self-alignment-X = #-1
\mark "Default naming"
\theChords \break
\mark "Interval-based naming"
\set chordRootNamer = #intervalic-namer
\theChords \break
\mark "Lowercase minor"
\set chordNameLowercaseMinor = ##t
\theChords \break
\mark "Custom alterations"
\set chordRootNamer = #intervalic-namer-custom-alts
\theChords
} >> \layout { indent = 0 } }
```
The above namer comes in two flavors, depending on whether you prefer
the normal glyphs for alterations or if you want to customize the
symbols.
The one thing this does not handle is ensuring the tonic of the current
key signature appears as "I". To do that appears to require more work
as `chordRootNamer` does not provide access to the context in order to
query for the current key. I believe you might need to go down the
route of a custom engraver. If you search on this mailing list, there
has been prior discussion about supporting the Nashville numbering
system (which admittedly is much more than just interval-based naming).
But in that thread, there is a lot of potentially relevant material to
this topic, such as getting the key signature information into the
ChordNames context.

Re: Intervalic Chord Names
That worked perfectly! Thank you. I am not very familiar with lilypond internals, but now I am also intrigued by your solution. I am determined now to learn scheme. :-) > > Do you need lowercase numbers (i to vii) too? And how about accidentals? > I am comfortable with IVm7 or IV-7 but I am curious how you would select lowercase ii, vi, etc.? If the chord is c:m7 would that choose lowercase somehow? That would be pretty cool. Now I'm thinking of expanding this to respect the key (e.g. if the key is changed to F, would the intervalic chords remain unchanged in the output?) I don't really need to do that; just wondering aloud. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

There are two possibilities what to do about that: 1. Get the tonic from the key signature as it is done in these snippets: http://lsr.di.unimi.it/LSR/Search?q=tonic 2. Use \transpose to transpose the chords to C. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Hello Tom,
Do I guess it right that you’d like tonality-relative numbers, i.e. V7 for A7
in D major?

It came through; it just seems like it was overlooked by many.
I need some help figuring out how to change chord names (C, F, G) into
intervals such as (I, IV, V). The short example below displays a timing diagram
for a melodic line, but I would also like to display the chords C7, F7 as
generic intervals I7 IV7. Manually setting the text would okay -- I'm not
looking for some kind of automatic translation, although that would be neat. I
know I can do this with markup, but I do not want to add markup statements to
noteValues! Do I need to set chordRootNamer somehow? Or is there another
solution? Thanks for any advice.
Setting chordRootNamer probably is the easiest way, yes. I took the
original definition of note-name->markup (which is the default
chordRootNamer) from the file scm/chord-name.scm and modified it to use
the roman numerals I to VII instead of letters C to B:
%
\layout {
\context {
\ChordNames
chordRootNamer =
#(lambda (pitch lowercase?)
(make-simple-markup
(vector-ref #("I" "II" "III" "IV" "V" "VI" "VII")
(ly:pitch-notename pitch
}
}
%
Of course you can use that in a \with block instead of a layout-context
block; or just \set chordRootNamer = … somewhere else ;)
Do you need lowercase numbers (i to vii) too? And how about accidentals?
