Notations for polyphony in the Wolkenstein codices

Marc Lewon

The defining aspect of these repertories is that they are unmeasured, which, when applied to Oswald, appears to be a contradiction in terms since all his surviving music is notated mensurally. The use and meaning of mensural notes in the Wolkenstein codices, however, appear to differ according to context: while the scribes made standard use of the notational signs for the contrafacta to precisely regulate the interaction of the voices, they applied the mensural note shapes more creatively for the other group of songs, describing rather than prescribing a practice for which notation—in principle—was not required.[7]

This latter use of mensural note signs can be further differentiated, and – in its different forms – abundantly occurs also outside Oswald’s song manuscripts. It can, for instance, be found in the Neidhart œuvre of the Eghenvelder Liedersammlung (» B. Kap. Eine studentische Neidhartsammlung aus Wien), in the Lochamer-Liederbuch (D-B Mus. ms. 40613), or in the manuscripts containing the songs of the Monk of Salzburg (» B. Geistliche Lieder des Mönchs von Salzburg; » B. Secular Songs of the Monk of Salzburg). It manifests itself primarily in two forms: a semi-mensural and a structural use. The semi-mensural use can consist of mensural note signs in an otherwise non-mensural environment (for instance, chant notation) to clarify small-scale rhythmic relationships, such as upbeats, the placement of surplus syllables, and so on, or to provide a suggestion for a general performance rhythm. It can, however, also appear in the form of a seemingly precisely rhythmised melody. This special case of semi-mensural usage comes with a syllabic underlay of a German verse text with alternating stresses and usually consists of a regular alternation between a longer and a shorter note value in triple metre, usually semibrevis and minima, representing accented and unaccented syllables, respectively. Occasionally it also appears in duple metre. The resulting musical rhythm is a depiction of the verse metre of the underlying text and serves as a point of reference rather than a prescription for the performer, which is why I named it ‘reference rhythm’.[8] Since the reference rhythm is generated from the text (unlike the first and second rhythmic modes of the >Ars antiqua<) it is descriptive and implies performative flexibility. This, in turn, means that the essence of the melodic structure is not affected by a performative deviation from the rhythmic profile. Besides, what at first glance may look like a coherent use of mensural notation reveals numerous inaccuracies when looked at more closely. This semi-mensural use of mensural notation functions under the assumption that its meaning is clear from the context.

The other irregular use of mensural notation, the structural use, is non-mensural in essence. Mensural note shapes are employed here to visualise the structure of a melody with no hint at a performance rhythm: minimas represent upbeats, semibreves are equivalent to the puncta of chant notation and serve to notate the pitches of a melodic line, breves and longas indicate cadence notes, and the semiminima is occasionally used as custos (» Abb. Structural use of mensural note shapes, Oswald von Wolkenstein).

An example for the structural use of mensural note shapes in Oswald’s manuscripts: The first metrical upbeat is marked by a minima, while the only other minima in the notation marks a split note to account for a surplus syllable; all middle notes are given as semibreves, the finals of both form parts are longas and the custos is represented by a (stylised) seminima.

Although notations in pure reference rhythm as well as pure structural use can be found in all the above sources, both forms can also flow into each other and interact freely with other forms of semi-mensural notation, such as >stroke notation<.[9] All of them, however, are mainly reserved to record monophonic songs. Their use for some of the polyphonic pieces in the œuvre of Oswald von Wolkenstein clearly links this repertory to the world of monophony. In fact, the majority of this repertory appears to be equivalent to the concept of ‘cantus planus binatim’ (» Kap. Zum Begriff der nichtmensuralen Mehrstimmigkeit) a sort of ‘embellished’ or ‘enhanced monophony’ that employs a wide range of practices including fifthing (‘quintieren’) and extemporising upper voices (‘übersingen’): two techniques that are actually mentioned in Oswald’s song texts. And, as regards the term ‘binatim’ (‘in pairs’), all of the Oswald songs in question are for two voices.

Another  comparable German repertory at the cross-roads between monophony and polyphony is the ‘polyphonic’ output of the Monk of Salzburg. Of his eight surviving polyphonic songs (all of them secular)[10] at least six contain aspects of non-mensural polyphony. Even though his compositions predate Oswald’s by at least one generation, the earliest transmitting sources appear only after the mid-fifteenth century, well after the Wolkenstein codices were written (WolkA, c. 1425; WolkB, c. 1432). The manuscripts with the Monk’s polyphonic songs present concordances in a wider range of sources and with a wider range of notations, including chant notation, which confirms this repertory’s affiliation to non-mensural polyphony as well as monophonic music. All voices in both repertories (Oswald’s and the Monk’s) are notated separately, according to contemporary custom – even though a notation in score format, which is usually found in the sources of sacred non-mensural polyphony (as for example » Abb. Viderunt omnes/Vidit rex, » Abb. Jube Domne – Consolamini), would have been more appropriate for a repertory that does not rely on exact rhythmic notation.
