Could you try this with your original file? (I can't think of an example with \RemoveEmptyStaves to check it with.) The function ly:stencil-scale needs a stencil to work with (hence the error you were getting), and this variant checks to see if we have one before calling it. \override GrandStaff.SystemStartBrace #'stencil = #(lambda (grob) (let ((brace (ly:system-start-delimiter::print grob))) (if (ly:stencil? brace) (ly:stencil-scale brace 0.75 1)))) Hope this helps! -David
