Dashes through numbers in notation


Hi all - I’ve been playing off some music scores recently which have this mark - a stroke through the number. I’ve noticed it’s only on positions 10 and above -what is the significance of this mark? Many thanks 15664977960496197901646307157266|374x500


I can’t see the image you posted, but I think I know what you are talking about. Those marks through the upper octave numbers are there because a “12” might look like a “1” followed by a “2” otherwise.


Thank you :slight_smile: I thought it might be something like that!
