Harm,

Thank you for your clear reply! This is starting to making more sense to 
me.

Since the VerticalAxisGroup is still set to nonstaff-nonstaff-spacing 
for Verse4, any changes to the padding push Verse3 below it (a nonstaff 
object) up or down. Correct? And, if I then change the VerticalAxisGroup 
setting to nonstaff-relatedstaff-spacing for Verse4, then it moves up or 
down in relation to the staff.


I still don't understand the behavior of the padding variable for some 
of the lyric lines.

Changed code copied below:
If I delete all of the alignAbove/BelowContext settings so that the 
lyric lines are all below the staff, and reset Lyrics1 to 
nonstaff-relatedstaff-spacing and Lyrics2, 3, and 4 to 
nonstaff-nonstaff-spacing, then:

The padding for Verse1 pushes Verse1, and all the other verses, up or 
down in relation to the treble staff.
The padding for Verse2 pushes Verse3 and Verse4 up or down. It does not 
move in relation to Verse1.
The padding for Verse3 pushes Verse4 up or down.
The padding for Verse4 has no effect.

It seems like Verses2, 3, and 4 are looking down when using the padding 
variable. How can I get them to look up to the verses and staff above? 
The command - \override VerticalAxisGroup.staff-affinity = #UP - does 
not change the looking down behavior for the padding variable.


Peace,
David
