Re: Roman Numeral placement

[SonusProj .]

Hi David.

I am the OP.

Looking at your example, you have a bit of code similar to another person who has assisted me.

 \markup \rN { I }

I can't find documentation for the escape sequence and it throws and error when I try to compile.

:14:11: error: unknown escaped string: `\rN'

\markup

\rN { I }

Can you shed some light on where this item is discussed in documentation and why I receive and error?

Regards,

Lance

I like to follow the discussions even if I don't understand/need something because I usually learn a lot and sometimes even adapt some ideas or code into something I can use later.

In this thread I was amazed that the scheme created could interpret the chords!!! I tend to analyze music (almost daily). Usually I print it out and go over it and mark in what I need. When I saw this i instantly tried it on some of my scores and was amazed.

Now where I was lost was -

1. is it possible to make it read polyphony? <<\top \\ \bottom>> without re writing it as a chord?

2. the ability to add it to any score as needed for analysis

If I'm understanding you correctly, you mean to be able to feed it, say, a Beethoven sonata and have it provide a Roman numeral analysis?  Sorting out harmonic rhythm, embellishing tones, deciding on the current key, etc.?Now that would be a lifetime's labor :)

The task is so complex with any but the simplest music, and there is so much room for alternate interpretation, that all that is feasible is a convenient way to format the symbols that the analyst requires.

As an example of a simple formatter, see the code here: http://www.mail-archive.com/lilypond-user%40gnu.org/msg96575.html

A more representative usage of the code at the link would be:

%%%%%%%%%%%%%%%%%  EXAMPLE %%%%%%%%%%%%%%%%%%%%%%

bassline = \relative c' {

  \clef bass

  \key g \major

  \time 3/4

  g4 fis f

  e es es

  d2 dis4

  e2.

  \bar "||"

}

analysis = \lyricmode {

  \set stanza = #"G:     " % use spaces to adjust position of key indication

  \markup \rN { I }

  \markup \rN { V 6 5 }

  \markup \rN { vii o 4 3 / IV }

  \markup \rN { IV 6 }

  \markup \rN { ii h 4 3 }

  \markup \rN { Fr + 6 }

  \markup \rN { I 6 4 }

  \markup \rN { vii o 7 / vi }

  \markup \rN { vi }

}

\score {

  \new Staff <<

    \new Voice = "bass" { \bassline }

    \new Lyrics \lyricsto "bass" { \analysis }

  >>

  \layout {

    \context {

      \Score

      \override SpacingSpanner #'shortest-duration-space = #6

    }

  }

}

%%%%%%%%%%

Hope this is helpful,

David
