Yes, definitely semibreve-semibreve.  An upstem to the left unambiguously denotes a c.o.p. ligature (cum opposite proprietate).  This takes precedence over the other rules for parsing ligatures, including the one that says that "everything from the second note to the penultimate note is a breve unless otherwise notated".  

And the one that would otherwise apply here: "final note in ascending position is a breve unless otherwise notated."

Willi Apel's book on polyphonic music says (p91) "An ascending tail to the left of the initial note makes that note and the following one a S each".  So it looks like the original was actually semibreve-semibreve, whatever the writer intended.

Hi Group,

how can I create this ligature?

<kSzsWblRGWpITKJv.png>

it should be Semibreve-Breve

but

\[ a1 h\breve \]

but lilypond states "Semibreve must be followed by another one"

Any idea?

Best regards
