Hello-
Sometimes in modern versions of early music, the editor uses the
symbology shown in the attached image to indicate a change in metre.
I've looked through quite a lot of the LilyPond documentation but
haven't been able to find any info about how to create this in a
LilyPond file.
It seems that there are two issues: how to create the "breve = dotted
breve" string (?), and how to position the result above the staff,
centred on the bar line.
Any guidance would be much appreciated!
Thanks
Peter
