The second bar loses the '\skip 8'.
Nope. Use bar-checks ;)
Cheers,

I must be missing something here!
The first bar of the 'eighthNotes' has durations: 8 x 8.
TOTAL = 8 quavers or 4 crotchets (1 bar in 4/4 time).
The first bar of the 'words' has durations: 8 + 4 + 8 = 2 beats, 8 + 8
+ 8 + 8 = 2 beats
TOTAL = 8 quavers or 4 crotchets (1 bar in 4/4 time).
Why does the lyrics bar 1 'words' result in "warning: barcheck failed
at 7/8"?
I've attached some code to append to your example. I don't know
what sort of music you're setting, but as you mentioned melismas,
I've added some slurs to show the effect they have.
Note how you need to set an associated voice, when using durations,
to get the "melismatic shift" in the lyric position.
When not using durations, both slurs and "_" lyrics will cause
this shift, as seen in the last two examples. Because I don't use
durations, I prefer "" rather than \skip, because \skip must be
followed by a duration, but that duration is meaningless and
could be misleading.
Cheers,
David.
I don't think that melisma or ties provide the answer.
As Thomas will see below, I don't normally use '\lyricsto' in my scores.
LilyPond recommends using "tiny examples"
(https://lilypond.org/tiny-examples.html), and the many lilypond-user
posts mention a Minimal Working Example (MWE).
I presumed (perhaps wrongly) that this applied to the User Group and bug
reports.
In this case, for clarity and maybe assist others, I've included the
complete source code and a screenshot of the output below.
I'm writing a drum score for a song called "Come Together" by "The Beatles".
Drums don't normally use ties. Each stroke generally has no sustain.
In parts of all of the verses, the drum rhythm is eighth notes on the
drums, with the lyrics "toe- jam foot- ball, he got".
I wanted to underline the part that both the lead and backup vocalists
sing together, that is "toe- jam foot- ball,".
The lead vocalist sings "he got" on his own.
Having tried numerous times to get this right with a tiny example/MWE,
the code that gives exactly what I want is below.
I would like to thank everybody who replied to my original post, and
subsequent follow-up posts.
LilyPond is such a wonderful tool for us musicians.
Here is the part of my score that I was trying to achieve in the first
place.
Taking all comments into account and modifying as necessary, here's the
resultant code (This includes code from the reply from Kieren MacMillan):

Thanks to all once again!
*_Footnote_*
I'd like to mention that Ringo Starr always used a Ludwig drum kit with
3 toms.
The LilyPond drumpitch-init.ly file for both LilyPond 2.24.0 and 2.25.21
has multiple options, including:
drums-style (default)
weinberg-drums-style
Both of these have the 'tomh' position as the top line, whereas the book
"GUIDE TO Standardized Drumset Notation BY NORMAN WEINBERG" recommends
the top space for a drum kit with 2 to 4 toms.
This is probably because the reference in the drumpitch-init.ly file for
Weinberg is based on a 1994 magazine article, whereas the book that I
have was published in 1998 (ISBN 978-0-9664928-1-1).
I attempted to rectify the Weinberg definition a couple of years ago,
but no action was taken.
I will work on an alternative definition, based on the book, which has
recommendations for drum kits with up to 10 Toms, and will create a new
post on that subject.
Again, I'd like to thank all in the lilypond-user for taking the time
and effort to assist all music lovers.
