Re: writing score in absolute time

Totally, now it begins the game. But at least I’ve a starting point!

I’ve to understand better the tempo and rhythmic values in lilypond.

I’ve already added the possibility to write cents for exemple for microtonality (a simple way).

There’s 2 more things I could not figure out:

- how can I allow the duration line to be over other notes

- now the possibility to range everything in an A4 format (I could do it with ImageMagick, but I wonder if lilypond could)

Updated code for those interested:

\version "2.24.0"

\paper {
    page-breaking = #ly:one-line-auto-height-breaking
}

\layout {
    \context {
        \Score
        proportionalNotationDuration = #(ly:make-moment 1/64)
        \override SpacingSpanner.uniform-stretching = ##t
        \override DurationLine.bound-details.right.end-style = #'hook
        \override DurationLine.thickness = 2
    }
    \context {
        \Voice
        \consists Duration_line_engraver
        \remove Stem_engraver
        \remove Dots_engraver
        \override NoteHead.duration-log = 2
    }
}

at =
#(define-music-function (instrument point pitch len cent) (string? exact-rational? ly:pitch? exact-rational? string?)
     #{ \context Staff = #instrument \after 4*#point { $pitch 4*$len \- } -#cent <> #})

<<
    \new Staff = piano { s1*10 }
    \new Staff = violin { s1*10 }
    \cadenzaOn
    \at piano ##e1.67 e' ##e1 "-31.75¢"
    \at piano ##e5.96 a' ##e2 "+7.51¢"
    \at violin ##e2.8 c' ##e3 "+38.42¢"
    \at violin ##e1.89 e' ##e4 "+14.04¢"
    \at violin ##e5.37 d' ##e5 "+23.6¢"

Amazing, really.
I lastly just wonder now, if it’s possible to write the duration in seconds.. But I understood that’s not the way of working of lilypond.
Thank you!

This can be done too.

\version "2.24.0"

Next problem: squeezing in the accidentals. One solution: a grand
staff with lines and spaces for each note of the chromatic scale.
Unintended benefit: punch out the inked sections and you've got
yourself a piano roll.

Cheers,
David.
