Re: How to make a blank page

[Paul McKay]

Hi

Many thanks to you all for your help. I thought you might like to know that I found Simon's solution the best one.

Perhaps my minimal example was a little too pared down. In reality, I use headers and footers on my music as well. So my minimal example begins:

Jean Abou's suggestion 

\version "2.24.0"

\language "english"

\header {    title = "Praeludium" }

myScore = \score { \relative { c'4 d e f g }}

\markup ""

\pageBreak

\myScore 

puts the header on the first page and the music on the second page.

With Simon's trick I can use a variable to push the header after the initial page break thus:

\version "2.24.0"

\language "english"

hdr = \header {    title = "Praeludium" }

myScore = \score { \relative { c'4 d e f g }}

\bookpart { \markup \null }

\bookpart { \hdr  \myScore }

I guess my concept of how \pageBreak should work was gleaned from having to use Microsoft Word. There you get a page break wherever you ask for one, even if it makes no sense. (Followed by space above the first paragaph on the page which is execrable. Don't get me started … )

Hello Silvain,

it might help to understand that \pageBreak is not an instruction to insert a
pageBreak. Think of \noPageBreak: This is a token that prevents a pageBreak to
happen at the given place. Similarly \pageBreak is a token that enforces a
pageBreak to happen at the given place (in other words the token must not
happen within one page).

Now, if you have

[ page1 ]
\pageBreak
[ page2 ]

and [page1] and [page2] are already two different pages the \pageBreak will not
do anything, as there already is a pageBreak. This is similar to how adding
\break at a line break will not cause an empty line. I’d suggest you do

\pageBreak
\markup\null
\pageBreak

The first \pageBreak will ensure that a new page is started, the second
guarantees that the follwing content starts on a new page. All in all this
will create an empty page, no matter where you insert it. You can even do a
function for this:

emptyPage =
#(define-scheme-function () ()
   (collect-music-aux add-score #{ \pageBreak #})
   (add-text (markup #:null))
   (collect-music-aux add-score #{ \pageBreak #}))

\emptyPage
\markup "a"
\emptyPage
\markup "b"

Cheers,
Valentin
