Thanks for the info. I was not aware of the differences.

The CSV that I posted matches https://data.musikpiraten-ev.de/public/k...singen.pdf (without -A4) which is linked from
https://musik.klarmachen-zum-aendern.de/...len-singen
(the second link in the first post).

There you can also find a link to the Lilypond files that were used to create the book:
https://musik.klarmachen-zum-aendern.de/files/kws.zip
Is anybody out there who is able to convert the Lilypond files to musicxml, MuseScore .mscz or .abc so that songs can be transposed?

The main difference between kinder-wollen-singen.pdf and kinder-wollen-singen-A4.pdf is that in the -A4 version more songs fit on a single page - probably better to use in MSP on a tablet.
