FIG.    1-10    Attic   Greek   amphora (jar),  ca.490  B.C.E., showing someone singing to  a   lyre.   Greek   music   theory  was mainly
confined    to  prescribing tunings for the lyre,   in  three   genera, or  types:  diatonic,   chromatic,  and enharmonic. These   words   have
survived    in  modern  musical terminology,    although    not with    precisely   the same    meanings.
Ex. 1-11b   contains    the earliest    surviving   artifact    of  actual  Christian   service music,  a   fragment    from    the
close   of  a   Greek   hymn    to  the Holy    Trinity,    notated on  a   papyrus strip   during  the fourth  century CE  and
discovered  in  1918.   The hymn    is  probably    a   translated  extract from    the liturgy of  the Syriac  Christian
church. Although    we  cannot  be  certain (since  it  is  our only    example),   it  seems   to  be  built   up  out of  a
diatonic    formula-family. It  is  the earliest    surviving   representative, by  six or  seven   centuries,  of  the Greek-
texted  music   of  the Orthodox    (that   is, official)   church  of  the Eastern Roman   Empire, known   as  the
Byzantine   Empire  after   Byzantium   (or Constantinople),    its capital until   1453.
EX. 1-11A   Second  stanza  of  the First   Delphic Hymn,   transcribed by  Egert   Pöhlmann    and Martin  L.  WestUnlike  the Western Roman   church, which   came    to  cultivate   the traditional prosepoetry of  the Psalter
