Hemiola [hemiolia]
(from Gk. hemilios: the whole and a half; Lat. sesquialtera; It.:
emiolia).
The ratio 3:2. The term was first applied to music in connection with the
theory of pitch: when the string of the monochord was divided in this ratio
the two lengths sounded the interval of a 5th. From the 15th century, it was
used to signify the substitution of three imperfect notes for two perfect
ones in tempus perfectum (mensuration with three semibreves to the breve) or
prolatio maior (three minims to the semibreve). Such substitutions, which
were usually notated using coloration, were widely used in 15th-century
music. They were particularly prevalent in the English carol repertory,
which was described by Bukofzer as hemiola music pure and simple (ex.1).
By extension, hemiola in the modern metrical system denotes the
articulation of two units of triple metre as if they were notated as three
units of duple metre: in ex.2, from Act 4 of Lullys Le bourgeois
gentilhomme (1670), the first bar contains two triple units, and the second
has three duple units. This is a common feature of Baroque music, especially
of the French courante, and is used for giving rhythmic variety to dances
and helping to effect an allargando at the end of a longer movement; Handel
made much use of it. In the 19th century it was used by Schumann and often
by Brahms, and was an important feature of the Viennese waltz. Hemiola is a
distinguishing feature of such folkdances as the Andalusian polo and the
Central American huapango, rhythmic characteristics of which were
incorporated by Bernstein into America from West Side Story (ex.3).

Post by Margo SchulterPost by Alain NaigeonOn saturday evening I've attended a concert by Mala punica
(Memelsdorff), playing Ars subtilior (1380-1400), and we've
listened to a lot of polymeter effects ;-) Including those
in Caserta's "Amour m'as le cueur mis...", and also "Dame
zentil" ! >
Hello, Alain.
Please let me agree: if people mention "polymeter," the late
14th century might be one of my first associations. The
specific figure of hemiola is something I associate with
this century, althoug, of course, it occurs later too.

where the lower voices are moving in 3/4 and the highest
in 6/8, if we take the minim to be transcribed as an
eighth note or quaver.
Anyway, those pieces are great examples, not to mention
Solage and Ciconia, among others.
Most appreciatively,
