⁠12.6.4.5. Continue to the Fast Section

If you want to finish inputting the first movement, as an exercise, then you will also need to know how to write a tempo-change in an orchestral score:
  1. In order to continue, we'll need to include a special measure-line (barline) and a change-of-tempo indicator. This would be easy, and would display correctly, if we simply inputted the change in one particular voice. However, if we did that, the change would only appear in one of the orchestral parts exported from the score.
  2. We're going to define a new whatever-thing, like the "global" section created for us by Frescobaldi, and include it in all of the parts.
  3. The code needed for this is a little bit complicated, but you don't need to write it yourself: just take it from the "tempoMark" section created by Frescobaldi. All you need to do is change "Adagio" to "Allegro spiritoso," and add the barline indicator. This is also easy because of Frescobaldi: 'LilyPond > Bar Lines > Repeat start'
  4. You end up with

    startExposition =
    {
      \once \override Score.RehearsalMark #'self-alignment-X = #LEFT
      \once \override Score.RehearsalMark #'break-align-symbols = #'(time-signature key-signature)
      \mark \markup \bold "Allegro spiritoso"
      \bar "|:"
    }

  5. Add the reference to this in all of your parts. Because of how I named it, this also serves as a handy way to find your way through the LilyPond markup file.

  6. The barline and tempo-change will not appear unless you write some music after them, so put in some or all of the rests that follow, just to test it.
