You can get the space between the beams from the 'gap property. (It's measured in half staff-spaces, so this value needs to be halved.) Also, you can get the number of beams through the 'beaming property. Here I've gotten the beam-count from the first stem. I hope this helps! \version "2.14.2" #(define ((stencil-plus-bracket beam-count) grob) (let* ((beam (ly:beam::print grob)) (beam-count (length (cdr (ly:grob-property (ly:grob-parent grob X) 'beaming)))) (beam-positions (ly:grob-property grob 'positions)) (gap (* 0.5 (ly:grob-property grob 'gap))) (single-beam-thickness (ly:grob-property grob 'beam-thickness)) (whole-beam-thickness (+ (* beam-count single-beam-thickness)(* (- beam-count 1) gap))) (bracket (ly:bracket Y (cons (* -0.5 whole-beam-thickness) (* 0.5 whole-beam-thickness)) 0.05 0.4))) (ly:stencil-add beam (ly:stencil-in-color (ly:stencil-translate bracket (cons -1 (- (car beam-positions) (* 0.38 whole-beam-thickness)))) 1 0 0)) )) \relative c' { \stemUp \once\override Beam #'stencil = #stencil-plus-bracket f'32 [f f f] \once\override Beam #'stencil = #stencil-plus-bracket f16 [f f f] \once\override Beam #'stencil = #stencil-plus-bracket f64 [f f f] } Best, David
