Dear Wontaek,
In response to your question about the two sequences, let me give you a
brief answer and then give you a few references.
Both the "Dies irae" and the "Victimae paschali laudes" are Sequences
(from the Latin word "sequere" to follow) "Dies irae" (abbreviated DI)
has the normal structure of a sequence, AABBCCDD etc. "Victinae
paschali laudes" (abbreviated VPL) also is pretty sequence-like:
ABBCCD. Both are essentially syllabic, and in that sense they are
similar. Both are in the first mode and therefore both have la for the
dominant and re for the final. However, VPL is for a joyful occasion
(Easter) and thus the extensive range is understandable, whereas DI
appears in the Mass for the Dead and thus the restricted, more reserved
range is appropriate. VPL is attributed to Wipo of Burgundy, who died
c. 1048. DI is attributed to Thomas of Celano, who died c. 1250.
Attributions are not proven facts, so we don't know for sure who wrote
either one of these sequences. The strict adherence to form in the DI
makes sense if it was written in the 13th century, when the trend was
toward uniformity.
Was DI, the later piece, based on VPL? I doubt if anyone can prove
this. However, in addition to their identity of mode and style
(essentially syllabic) notice that the notations for the "Amen" and the
phrase immediately preceding it are quite similar. Bearing in mind that
many Gregorian melodies were composed by the use of centonization
(patching together bits of pre-existing melodies in the same mode),
Thomas could very well have depended somewhat on Wipo in places. Another
consideration, the notation for the Amen is a very common first mode
notation for Amens. So our composers needed notes for the Amen. So
they used what they knew. Noone knows who used it first. There were no
copyright laws!
I mentioned above that the word "sequence" comes from "sequere" to
follow. A sequence, following something and growing out of it, is
therefore a trope, that is, an addition within or after another piece.
Some think that the DI may have originally been a trope based on "Dies
illa, dies irae" in the Responsory, "Libera me" in the Burial service
(page 1767, line 6 in the Liber Usualis). The words and the notation
are very similar.
For additional information on these two sequences, you might check the
following:
1. Purdue Humanities Library No. 780.902H778M. This is Richard Hoppin's
MEDIEVAL MUSIC. Someone has this book presently, but the librarian
could recall it for you.
2. Purdue Humanities Library No. 783.5AP22G. This is Willi Apel's
GREGORIAN CHANT. This book is available.
3. THE NEW GROVE'S DICTIONARY OF MUSIC AND MUSICIANS under such articles
as Dies Irae, Victimae paschali laudes, Sequence. In John Caldwell's
article on Victimae paschali laudes, you will note that he states that
the VPL was apparently not an accommodation of a previously composed
melody.
Next summer's Chant Institute is tentatively scheduled for June 20-27
and will be in 2 parts. Part 1 will be for new students and also for
returning students who wish to attend, Part 2 will be for those who
will have attended Part I and also for returning students who took the
l998 or l999 Institute for credit. One graduate credit will be
available for those taking Part 1 (unless they already have this credit
from 1998 or 1999). One graduate credit will also be available for Part
2. Anyone may audit either Part 1 or Part 2 or both. I will be honored
to have you for either or both parts. More information will be
available later and I shall be sure to send you this.
I am honored that you wish to send my other e-mail to your friends in
Korea. Please feel free to do so.
I am also happy that you have friends who might wish to enroll in our
Program. If you will be kind enough to send me names and addresses,
Ishall be grateful.
All good wishes of this holy season and for the New Year.
Fr. Larry Heiman
