Flat flags and beam nibs

Flat flags on lone notes and beam nibs at the ends of beamed figures are both possible with a combination of stemLeftBeamCount, stemRightBeamCount, and paired [] beam indicators.

For right-pointing flat flags on lone notes, use paired [] beam indicators and set stemLeftBeamCount to zero (see Example 1).

For left-pointing flat flags, set stemRightBeamCount instead (Example 2).

For right-pointing nibs at the end of a run of beamed notes, set stemRightBeamCount to a positive value. And for left-pointing nibs at the start of a run of beamed notes, set stemLeftBeamCount instead (Example 3).

Sometimes it may make sense for a lone note surrounded by rests to carry both a left- and right-pointing flat flag. Do this with paired [] beam indicators alone (Example 4).

(Note that \set stemLeftBeamCount is always equivalent to \once \set. In other words, the beam count settings are not “sticky”, so the pair of flat flags attached to the lone c'16[] in the last example have nothing to do with the \set two notes prior.)

\score {
  <<
    % Example 1
    \new RhythmicStaff {
      \set stemLeftBeamCount = 0
      c16[]
      r8.
    }
    % Example 2
    \new RhythmicStaff {
      r8.
      \set stemRightBeamCount = 0
      16[]
    }
    % Example 3
    \new RhythmicStaff {
      16 16
      \set stemRightBeamCount = 2
      16 r r
      \set stemLeftBeamCount = 2
      16 16 16
    }
    % Example 4
    \new RhythmicStaff {
      16 16
      \set stemRightBeamCount = 2
      16 r16
      16[]
      r16
      \set stemLeftBeamCount = 2
      16 16
    }
