Re: Jazz chords layout question

[Jacques Menu]

Another, tricky ‘solution', though musically incorrect since:

- it doesn’t use \repeat: the repeat barlines are added manually;

- it adds two hidden skip full measures to push the seconda volta to the right.

However:

  \set Score.repeatCommands = #'((volta ""))

  <> ^\markup {

    \scale #'(1.5 . 1.5)

    \column{

      \line\large { "1." }

    }

  }

produces a hooked line above the staff, but:

  \set Score.repeatCommands = #'((volta ""))

  <> ^\markup {

    \scale #'(1.5 . 1.5)

    \column{

      \line\large { "2." }

    }

  }

doesn’t.

Hello Robert and Carl,

Thanks for your help!

To summurize, after checking the docs for marks:

- why do the marks appear without a box around them?

because using ‘\mark "A"’ precludes the box.

Since the AABA scheme is so common in jazz, using:

\mark \markup {\box "A" }

solves the issue.

- why does \repeat percent not produce percent signs?

because the percent repeat engraver is not used by ChordNames by default.

Thus:

\new ChordNames \with { \consists Percent_repeat_engraver }

solves the issue.

- how can I get the measures to be equal length?

by using proportional notation duration:

\layout {

  \context {

    \Score

    proportionalNotationDuration = #(ly:make-moment 1/8)

  }

}

and indents:

\paper {

  #(set-paper-size "a4")

  indent = 0\mm

  short-indent = 0.9\cm

- how can I ‘push’ the beginning of the seconda volta to the middle of the line?

that seems difficult, no solution at this time

I attach the resulting score for the record.

A nice w-e!

JM
