I am trying to learn Harehop by Sigrid Arneberg, and it has a strange sequence of repeat signs.
The music has a right facing repeat sign as if there will be a left facing one to mark where to go back, but then there is another right facing sign before finally reaching the left facing symbol.
As ASCII art, the repeat structure looks like this:
| :|| ||: ||: :|| ||
Is this an error in the transcription, or is there a way that you are supposed to interpret that, that I do not know of?
I was using MuseScore to hear it for myself and it doesn't do anything special. The score for reference can be found at: https://imslp.org/wiki/Harehop_(Arneberg,_Sigrid)
