Displaying figured bass

Figured bass can be displayed using the FiguredBass context, or in most staff contexts.

When displayed in a FiguredBass context, the vertical location of the figures is independent of the notes on the staff.

     
     <<
       \relative c'' {
         c4 c'8 r8 c,4 c'
       }
       \new FiguredBass {
         \figuremode {
           <4>4 <10 6>8 s8
           <6 4>4 <6 4>
         }
       }
     >>

In the example above, the FiguredBass context must be explicitly instantiated to avoid creating a second (empty) staff.

Figured bass can also be added to Staff contexts directly. In this case, the vertical position of the figures is adjusted automatically.

     
     <<
       \new Staff = myStaff
       \figuremode {
         <4>4 <10 6>8 s8
         <6 4>4 <6 4>
       }
       %% Put notes on same Staff as figures
       \context Staff = myStaff
       {
         \clef bass
         c4 c'8 r8 c4 c'
       }
     >>

When added in a Staff context, figured bass can be displayed above or below the staff.

     
     <<
       \new Staff = myStaff
       \figuremode {
         <4>4 <10 6>8 s8
         \bassFigureStaffAlignmentDown
         <6 4>4 <6 4>
       }
       %% Put notes on same Staff as figures
       \context Staff = myStaff
       {
         \clef bass
         c4 c'8 r8 c4 c'
       }
     >>

Known issues and warnings

To ensure that continuation lines work properly, it is safest to use the same rhythm in the figure line as in the bass line.

     
     <<
       {
         \clef bass
         \repeat unfold 4 { f16. g32 } f8. es16 d8 es
       }
       \figures {
         \bassFigureExtendersOn
         % The extenders are correct here, with the same rhythm as the bass
         \repeat unfold 4 { <6 4->16. <6 4->32 }
         <5>8. r16 <6>8 <6\! 5->
       }
     >>
     <<
       {
         \clef bass
         \repeat unfold 4 { f16. g32 } f8. es16 d8 es
       }
       \figures {
         \bassFigureExtendersOn
         % The extenders are incorrect here, even though the timing is the same
         <6 4->4 <6 4->4
         <5>8. r16 <6>8 <6\! 5->
       }
     >>

When using extender lines, adjacent figures with the same number in a different figure location can cause the figure positions to invert.

     
     <<
      { fis4 g g, e' }
       \figures {
         \bassFigureExtendersOn
         <6 5>4 <5\! 4> < 5 _!> <6>
       }
     >>

To avoid this problem, simply turn on extenders after the figure that begins the extender line and turn them off at the end of the extender line.

     
     <<
      { fis4 g g, e' }
       \figures {
         <6 5>4 <5 4>
         \bassFigureExtendersOn
         < 5 _!>4 <6>
         \bassFigureExtendersOff
       }
     >>
