notes   in  transcription)  implies a   grouping    of  three   breves  into    perfect longs.  That    sort    of  supple, “natural”
artfulness—artfulness   within  apparent    simplicity—is   the mark    of  a   really  successful  assimilation    of  the
“English    sound”  into    the continental literate    tradition.
We  have    already met Guillaume   Du  Fay (d. 1474)   in  chapter 8,  and know    from    his extraordinary   motet
Nuper   rosarum flores  that    he  was an  extremely   ambitious   composer.   He  had a   brilliant   international
career, with    phases  in  Italy   (including  a   stint   in  the papal   choir)  and at  the court   of  Savoy,  a   duchy   in  the
Alpine  region  of  what    is  now eastern France  and western Switzerland,    before  returning   to  his native
region  as  a   canon   at  the cathedral   of  Cambrai,    near    the present-day border  of  France  and Belgium.    His
setting of  the Marian  hymn    Ave maris   stella  (previously encountered as  Ex. 2-7a),  while   also    fairly
modest  as  befits  the genre,  is  more    ornate  than    Binchois’s  and assimilates the chant   melody  much    more
thoroughly  to  the style   of  the courtly chanson (Ex.    11-24). As  befits  Du  Fay’s   glamorous   career  and his
comprehensive   stylistic   range,  even    his hymn    settings    are unmistakably    the work    of  the most    enterprising
composer    of  the age.
This    greater assimilation    is  accomplished    in  two ways.   First,  Du  Fay’s   chant   paraphrase  is  far more
decorative  than    Binchois’s; there   is  nothing in  the Binchois    setting like    the first   measure of  Du  Fay’s,  in
which   the plainchant’s    opening leap    of  a   fifth   is  filled  in  with    what    amounts to  an  original    melody. The
cadential   structure   of  Du  Fay’s   setting is  also    much    freer   from    that    of  the plainchant  than    Binchois’s—and
quite   purposefully    so. The first   cadence,    for example,    joins   the finishing   note    of  maris   to  the first   note    of
stella, creating    a   stopping    point   on  C,  a   note    to  which   no  cadence is  made    in  the original    chant.  The
alternation of  cadences    on  C   and D   thus    obtained    in  the first   half    of  the setting is  then    replayed    in  the
second  half    (C  on  virgo,  Don porta), creating    a   bipartite   structural  symmetry    not at  all typical of
plainchant  melodies    but very    typical of  courtly songs,  whose   “fixed  forms”  always  comprised   two main
sections.
Even    more    boldly, Du  Fay writes  an  alternate   third   part,   labeled “contratenor    sine    faulx   bourdon,”
that    replaces    the “derived”   fauxbourdon voice   with    a   full-fledged    contrapuntal    line    that    behaves exactly
like    the traditional chanson contratenor.    It  occupies    the same    register    as  the tenor,  with    which   it  frequently
crosses.    The first   crossing    is  a   marvelous   joke,   in  fact.   The first   measure of  the new contratenor coincides
with—or rather, is  disguised   as—the  beginning   of  the fauxbourdon realization,    so  that    when    the downbeat
G   replaces    the expected    F#  in  the second  measure,    it  comes   as  an  attention-grabbing  surprise.   That    G
forms   a   chord   with    the other   voices—a    chord   that    simply  cannot  occur   in  a   fauxbourdon.    The contratenor
stays   under   the tenor   all the way to  the end of  the fourth  bar,    completely  changing    the harmonization   of  the
chant-derived   part    and converting  the setting for all practical   purposes    into    a   chanson.    Then    the
contratenor reverts to  its initial position    above   the tenor   by  leaping an  octave, which   (as we  will    see in  a
moment) was a   most    typical sort    of  cadential   behavior    for a   chanson contratenor at  this    time.   All in  all,
Du  Fay’s   setting shows   him to  be  a   singularly  self-conscious  artist  and one especially  aware   of  the
distinguishing  features    and requirements    of  genres. As  we  have    observed    before, that    sort    of  awareness
enables an  artist  to  play    upon,   and fully   engage, the expectations    of  an  informed    audience.
