quence as far as 4a (7) Eterni [in the transcription of the music below

The words of the sequence are also printed in Missale Nidrosiense.
By adding all the fragments together, we can give a transcription
of the music of almost the whole sequence; only in v. 5 is anything
lacking. This gap has been filled out from the Oxford MS. which
has been of service earlier.
The title of the melody is taken from the Versus Alleluiaticus de
Communi Abbatum (Confessorum) “Iustus ut palma florebit” etc.;
and it is the same as that of “Laus tibi Christe cui”, “Sancti bap-
tiste”, and “Organicis canamus” (see the next sequence), yet with
some differences.
One difference is that “Laus” and “Sancti” begin with a verse
(without parallelism), to which neither “Adest” nor “Organicis”
has a pendant, so that v. 1 of the latter two sequences corresponds
to v. 2 of the former two, and so forth.
Another difference, though it is of minor importance, is that the
melody has had to accommodate itself to numbers of syllables which
differ from those in the corresponding places in the other sequences
which use the same melody. For instance: the three notes a, c, d,
which in “Laus” (“O Christi”) and in “Sancti” (“Placatus”) are
connected with three syllables, beginning v. 6a, but without parallel
in v. 6b, and which are repeated in the end of both halves of this
verse, become in (v. 5 of) “Adest” (“O beate”) a, c-b, c, d, and in
(vv. 4 and 5 of) “Organicis” (“Qua sine cuncta” and “Qua iusti
bene”) a, c-b, c, d, d.
In the following verses a real problem arises. Moberg (No. 17), who
presents this melody in connection with the text “Sancti baptiste”,
says that 2 of his 11 sources write v. 6 ( = v. 5 of “Adest”) with the
notes D, F, G, etc., so that the verse ends with G, and that one of these
two sources writes the next verse in the same level, beginning and
ending with G; and he has followed these sources in his publication.
