I have a 28" w x 14" high section of once a much larger sheet, perhaps the bottom half. It is 16th-century music handwritten as three lines of 4-line red music staff, containing black square and diamond notes. The staff lines are about 1.5" tall and the black text is 1.25 inches, all lower case. The folded piece is in a very rippling state.
By the way, the Latin lyrics on the exposed side of the vellum (in a frame) are, "My son who praises the angel who made the cherubim and the seraphim."
I see above the suggestion to use humidity. Any additional suggestions as to how to deal with the fold or ripples?
Thanks
Brian
