I’m studying many scores and have come across a ‘dotted bar line’. The first time I have encountered this.
After some initial research I do see their purpose. To make the music clearer to understand, used especially if rhythms are complex or unusual. I’m not surprised to find this in a Stravinsky score (Symphony in C), his music is complicated.
Notice though how some are shaped full height of the staff and some just in the middle covering two spaces. Some even just at the top (bar 2 Violin 1) or bottom.
Going off this, there doesn’t seem to be a standard notation. Resources online show one of full height. Why are some shaped, dotted differently?
