Re: strange detached beam issue

[Jin Choi]

Thanks, you were right. There was an unterminated Slur.outside-staff-priority override that was causing the problem. This snippet displays the flying beam:

\version "2.24.1"

top = { \change Staff = "upper" \voiceTwo }

bottom = { \change Staff = "lower" \voiceOne }

upper = \relative c'' {

  \override Slur.outside-staff-priority = #300

  

 \time 2/2

 \key c \major

 \voiceOne

 r8 bes'\mf( a gis a ees d cis |

 d bes a gis a ees d cis |

 d) bes'\dim( a\! gis a ees d cis |

 d[ \bottom bes a gis] a[ ees d)] r8 |

 \top 

 \oneVoice

 r8\p

}

lower = \relative c' {

 \clef bass

 a4 r8 \top bes'( a gis a ees |

 d cis d \bottom \voiceTwo bes a gis a ees |

 d cis d bes' a gis a ees |

 d cis d bes a gis a cis | 

 \oneVoice

 fis,4)

}

\score {

 \layout {

   \context {

     \Staff

     \consists Merge_rests_engraver

   }    

   \context {

     \PianoStaff

     \override StaffGrouper.staff-staff-spacing.basic-distance = #11

     \override TextScript.avoid-slur = #'outside

     \override TupletBracket.bracket-visibility = ##f

   }

 }  

 \new PianoStaff {

   <<

   \new Staff = "upper" \upper

   \new Staff = "lower" \lower

   >>

 }

}

I note some other differences between your image and what the code sample generates, in the slur and dynamic positions.

I can't suggest what in particular is happening, but if this happened to me, I'd be looking for an earlier tweak or override which hadn't been cancelled.

Subject: strange detached beam issue

I have a section of piano music where two voices start in the treble clef and subsequently move down into the bass clef. When the right hand moves down, the beam stays in the treble clef unattached to anything:

When I try to isolate this section, the problem does not occur. I am mystified as to what is going on. What might be some things I could try?
