We tried using \cadenzaOn to get the unmetered aspect, but the
fundamental problem is that \cadenzaOn turns off autoBeam, which in
turn means that manual beaming in a cadenza creates unwanted
melismata.

So turn the autobeaming back on.  I often use the combination of
\cadenzaOn \autoBeamOn', for exactly this reason.

Huh.  Sounds like LilyPond does something wrong here.  Should \cadenzaOn
leave autobeaming alone?  Would this have more effects than different
melismata?

The aim was to get vocal style beaming in beats, so that two eights are beamed and four eights are beamed in twos. Using \cadenzaOn and autoBeamon gives instrumental beaming, so three eights are beamed together, rather than as a single eigth and a beamed pair. For greater clarity, here is what I mean:

\version "2.17.29"

\language "english"

\header {

title = "Thou Shalt Know Him"

instrument = "Soprano 3 bars"

composer = "Mark Sirett"

}

bln = \bar "|"

\score {

% cadenza plus autobeam doesn't mess up lyrics but doesn't beam the eights properly

\relative c'' {

\key e \major

\cadenzaOn\autoBeamOn

\autoBeamOn

e,8^"autobeam" b' \bln b4. gs8 fs gs \bln e2

\cadenzaOff

}

\addlyrics { Thou shalt know Him when He comes }

\layout { }

}

\score {

%cadenza and manual beaming, per the manual, creates unwanted melismas

\relative c'' {
