I'm trying to clearly put apart a single coda staff from the rest of the part. Pretty sure a common thing. The thing is I'm lost :)
The file structure its easy (example):
###
\version 2.14.1
melody = { a a a a | c c c c | blah blah blah blah large one voice part }
% a simple 3 bars coda. codaPart = { b b b b | d d d d | a2. r4 \bar "|." }
\score { \melody
% clearly blank space for separating coda from part. As minimum of the default space or lets say height of a staff. % try adding lots of \break s do nothing ;)
