\once \override HorizontalBracket.bracket-flare = #(cons num num)

should work.
HTH,

Dear scheme experts,I am trying to supply a constructed pair as a value for a grob property in a music function, but it seems no matter what I try I get an error such as: `warning: type check for `bracket-flare' failed; value `(num . num)' must be of type `pair of numbers''. A non-working example is pasted below. In addition to the code below, I also tried binding the variables in advance with let* and I tried constructing the pair with cons. I even tried binding a value to the constructed pair, but everything returned the same error. Please help!Kevin\version "2.18.2"rotateBracket =#(define-music-function (parser location num)(number?)#{\once \override HorizontalBracket.bracket-flare = #'(num . num)#})\relative {\rotateBracket #1b\startGroup b\stopGroup}\layout {\context {\Voice\consists "Horizontal_bracket_engraver"}}
