Comment #25 on issue 2246 by address@hidden: beaming in 3/4 - a  
setting to not beam 3 eights against the beat.

In traditional music, "Fiddler's Fakebook" (1982) from Oak Publications  
(not B&H, but a careful publisher) consistently beams eighths to the beats,  
{r4. a8 a[ a] | a[ a] a[ a] a[ a]}.  This style was already available with  
2.14

We had strict-to-the-beat-beaming in 2.14 with  \set Timing.beamExceptions  
= #'()

The option we were missing from 2.14 was to automatically beam 6-eighths  
but not 3 (the Ted Ross rule) and we still lack that ability in the  
development version :

\new PianoStaff <<
  \new Staff \relative f {
    \time 3/4 \partial 4
    %\set Timing.beamHalfMeasure = ##f
    %\set Timing.beamWholeMeasure = ##t
    %\set Timing.beamExceptions = #'()
    e''8 dis e dis e b d c a4 r8 c, e a b4 r8 e, gis b
    c4 r8 e,8 e' dis c16 g' g, g' a, g' b, g' c, g' d g
  }
  \new Staff \relative f {
    \clef bass r4 R2.
    a,8 e' a r r4 e,8 e' gis r r4 a,8 e' a r r4
    R2. } >>

If there is a simple way to have an option forbidding beams starting or  
ending mid-measure in 3/4, we could follow the Ross rule.

Not all rules should be followed, though.  I was taught "'I' before 'E'  
except after 'C',"  I get wierd output when, motivated by iether sceintific  
vigor or a surfiet of liesure, I sieze upon /that/ anceint rule with  
efficeincy.   --Kieth
