Dear Pierre Perol-Schneider, I am sorry, but \bar ".|:" and \bar ":|." did
not work.
Dear Kieren MacMillan, I am sorry, but "\omit BarLine" did not work.
Indeed, it did omit bar lines, but the composition ran off the left margin
of the page.
Dear Laura Conrad, I am sorry, but your solution also did not work, the
behaviour was the same as that of Ms. MacMillan's solution.
For all of the above three tests, I included the Bar_engraver and removed
the statement regarding \set ScoreTiming.
Dear j...@abou-samra.fr, it looks like your solution does indeed work!
Thank you for your careful work.
And to answer one question which arose: the idea to remove the bar engraver
is included in the manual under chant music.
I would like to thank everyone who provided answers! This is not something
I could have found time to figure out myself, and I certainly wish one of
the simpler solutions would have worked.
Happy New Year! Bonne et heureuse année!
Sincerely,
John Staško
