Re: Suggestion: \breathe should include a \noBeam default option

[Mats Bengtsson]

Your attempt can be simplified, see below. However, after having tried it
on a simple example, I'm no longer so convinced that it's a good idea, since
you typically might want the notes before the breath to be beamed together,
whereas the (equivalent of ) \noBeam removes the beam completely.
This means that you still will have to manually specify the start and
end of the beam.

% Alternative definition of \breathe that also does \noBeam
breathenobeam =
#(define-music-function (parser location) ()
           (make-music 'EventChord
             'origin location
             'elements (list (make-music 'BreathingEvent)
                         (make-music 'BeamForbidEvent))))

% Using default \breathe
\relative c'{
c8 d e \breathe f g f e \breathe d }

% Using the new one
\relative c'{
c8 d e \breathenobeam f g f e \breathenobeam d }

% What you probably want typeset => \breathe and \breathenobeam are just 
as bad
\relative c'{
c8[ d e] \breathenobeam f g[ f e] \breathe d }
