Adding a figured bass above or below the notes

When writing figured bass, you can place the figures above or below the bass notes by using the commands \bassFigureStaffAlignmentDown and \bassFigureStaffAlignmentUp. Prepend \once to the command if you want to modify only the next figured bass.

The command \bassFigureStaffAlignmentNeutral resets the direction of figured bass to the default value.
