Re: help with cross-staff piano beams and stems

[Sepand Shahab]

Thanks very much, Xavier.

After the passage how can I revert the stem length, flag, and direction settings to their default values?


     % extend the stems to reach the other staff
     \override Stem #'length = #15
     % do not print extra flags
     \override Stem #'flag-style = #'no-flag    
     % stems should be up
      \stemUp

many thanks,
Sepand

I would use something like this.
Please note that explicit  Voice  creation is needed due to the fact
that we use a  \change Staff  at the very beginning of "upper".

\version "2.12.3"

upper = \relative c' {
 \clef treble

 \change Staff = "Staff_pfLower"
 <c,, c'>8
 \change Staff = "Staff_pfUpper"

 <d'' e>16 <d e>
 <d e> <d e> <d e> <d e>
}

lower = \relative c, {
 \clef bass

 % stems may overlap the other staff
 \override Stem #'cross-staff = ##t
 % extend the stems to reach the other staff
 \override Stem #'length = #12
 % do not print extra flags
 \override Stem #'flag-style = #'no-flag
 % stems should be up
 \stemUp
 % prevent autobeaming
 \autoBeamOff
 s8  <a'' b>16 <a b>

 <a b> <a b> <a b> <a b>
}


\score {
 \new PianoStaff = "PianoStaff_pf" <<
   \new Staff = "Staff_pfUpper" <<

     \new Voice = "Voice_pfUpper" {

       \upper
     }
   >>
   \new Staff = "Staff_pfLower" <<

     \new Voice = "Voice_pfLower" {
       \lower
     }
   >>
 >>
}


Cheers,
Xavier
