Re: Shorten a beam stem length

[Andrew Bernard]

Hi Joe,

Set Beam.positions.

I use this concept continually, for my work, in almost every bar. Here are a couple of utility functions I wrote that you may find handy. Nothing special, just convenient.

setBeamPos =

#(define-music-function

  (left right)

  (number? number?)

  "Manually set beam position for next group."

  #{

    \once \override Beam.positions = #(cons left right)

  #})

setBeamPosAll =

#(define-music-function

  (left right)

  (number? number?)

  "Manually set beam position for following groups."

  #{

    \override Beam.positions = #(cons left right)

  #})

Also, in your code, if you mean a length of 1, just use #1 for Scheme, not #’(1) as you had.
