Sumer Is Icumen In: Cuckoo for Canons

Album: Between March and April
Track: "Sumer Is Icumen In" (Track #20)
Composer: Anonymous
Instruments: 4 voices
Musical Form: Canon
Year: ~1250


Before I continue my Hopeless Journey into the Renaissance, I'd like to take a quick step back to mid-13th century England. You'll notice that England has been completely absent from my coverage of medieval music -- the primary reason for this is the scarcity of available sources. Most polyphony from the medieval period was sacred and the majority of English sacred music was destroyed during the dissolution of the monasteries, part of the English Reformation, in the 16th century. Fortunately, some English secular music has survived to the present day, including the famous canon, "Sumer Is Icumen In."

The canon really is a remarkable musical form: simple in structure, but complex in its presentation. A canon usually begins with a single musical line, sung by one or more singers. Before the line is completed, another voice begins singing the same (or a similar) musical line after a specified duration of time. Depending upon the complexity of the canon, this process can be repeated an arbitrary number of times, with new vocies appearing at intervals specified by the composer. To American ears, the most familiar canon is probably, "Row, row, row your boat," a campfire song written sometime in the 19th century. For that song, the second singer begins after the first has completed one measure, the third after he has completed two, and so forth.

"Sumer Is Icumen In" is similar to "Row, row, row your boat" in that it is a simple, light-hearted song that could conceivably have been performed for children (it means, quite literally, "Summer has come in"). It was written for six parts and is actually the first known example of six-part polyphony. Canons didn't really rise to prominence in sacred (or "artistic") music until the late 14th century, when the technique was pioneered by Italian composers and it wasn't until the mid 15th century that it began to catch on in the rest of Europe. Needless to say, these canons contained a great deal more complexity and depth than "Sumer Is Icumen In."

Ma Fin Est Mon Commencement: Bound by Symmetry

Album: Machaut: Chansons
Track: "Ma Fin Est Mon Commencement" (Track #13)
Composer: Guillaume de Machaut
Instruments: 3 voices
Musical Form: Rondeau
Year: ~1330-1350


There is something about symmetry, whether visual, auditory, or even tactile, that appeals to the human mind. We associate it with beauty, perhaps as much due to the ease with which we process it as its association with genetic quality in a mate. Although it is more often associated with the visual arts, musicians have been using symmetry in their compositions for millenia, allowing its predictability to massage our subconscious as we tackle the artist's larger purpose.

Perhaps the most striking demonstration of symmetry in medieval polyphony is in "Ma Fin Est Mon Commencement," a rondeau by Guillaume de Machaut. Even a passing familiarity with the French language (modern or otherwise) should allow one to translate the title: "My end is my beginning." And so it is -- the musical lines in this piece each display a certain symmetry. The lowest voice, the tenor, sings a line that sounds identical when sung in reverse. Furthermore, the cantus (2nd voice) and triplum (highest voice) sing lines that are the mirror images of one another. The net result is something that feels strikingly familiar, even on a first listen. I think this familiarity sprung from a subconscious recognition of the underlying patterns in the piece; I doubt I would have picked up on the symmetry without being told.

Indeed, large-scale patterns were the norm in the ars nova, as isorhythm dominated the rhythmic structure of motets during that period. It seems likely that this piece also bears some relation to a burgeoning art form, the canon (more on this soon), although it predates the widespread use of that technique in French polyphony. It is certainly not Machaut's best work, but its novelty value alone makes it worth a listen.
