Edited to give others a chance to think.
I have no clue, but this is a good thread. I often run across things in antique/junk stores that no one has any idea of what it's use was.
Used in music class to place a staff on the blackboard (not white board; blackboard!)
Yes but at least they were in sync!
I earned a BA in music theory in 1977 so I know those things real well. Yes, they can make some horiffic sounds on the right blackboard. You actually had to keep bending the wire holders into place and putting in new chalk or else you got only four lines or uneven spacing.
I imagine the computing world has really turned many aspects of learning music theory on its ear - you can create music notation in a flash now, and play it back in any voice you want ... synthesizers that used to cost upwards of $5,000 are now outclassed by a $100 Casio keyboard ...
