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 analysisIf 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.htmlA more representative usage of the code at the link would be:%%%%%%%%%%%%%%%%% EXAMPLE %%%%%%%%%%%%%%%%%%%%%%bassline = \relative c' {\clef bass\key g \major\time 3/4g4 fis fe es esd2 dis4e2.\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
