Harmonic adjustment

On top of the harmonic element of cadential progressions, harmonic adjustments work in much the same way as melodic ones, but in the realm of the vertical interaction between the voices rather than horizontal logic. Here too it is helpful to remember the medieval habit of notation in parts rather than in score. It is clear that some degree of forward planning and pre-preparation was important for any performance just as it still is today, and that this resulted in each performer having a good idea of what is about to happen next at any given point. Still, this notational characteristic has implications on the way music is learned and memorized, and suggests a culture in which the reaction to what has just been heard within the ensemble is more common than adaptations to what may or may not happen in another voice in the future.

As with the melodic corrections, some adjustments are straightforward.

Sound and Score     ¦     Facsimile

In this extract, the triplum has ample time to realize the contratenor is holding a protracted F-sharp to make sure its passing note chimes with its surroundings, even though there is no melodic reason for the addition. At other times, the immediate preceding information should be ignored in favor of a larger picture, or indeed, the melodic pattern.

Sound and Score     ¦     Facsimile

In this extract, a sensitive tenorista may notice the contratenor’s B-natural in bar 45 – which suggests a progression towards C – and would be tempted to keep his or her following B at the beginning of bar 46 natural as well. This, though, will clash with both cantus and triplum, create a tritone leap (or snowballing ficta), and a rather less likely plagal cadence at the end of the piece. Flattening the B solves all these problems, and is melodically more satisfactory. As explained when previously looking at this section, it can also be seen as implied by the preceding E-flat.

Judging whether to follow audio cues or ignore them can be a delicate task. When no obvious correction is required or an internal logic can be found for the reading adopted, I would recommend privileging individuality and melodic considerations over score-based adaptations. Again, this can be seen part of the medieval musical set-up. As the materials available to a performer were more likely to be linear than horizontal (be that in each performer’s memory or on the page), melodic consideration seem likely to carry more weight than harmonic ones. In many cases, following a sufficiently strong and clearly oriented melodic ficta logic leads also to satisfactory harmonic results, with any resulting clashes resolving themselves in an understandable manner. 

Such an example can be seen in the extract from B41 already discussed for its dissonant nature.

Sound and Score     ¦     Facsimile

The clear cadential progression to C in all voices would guide the ear through the strong dissonances of bar 22. These include the simultaneous transition from E-natural to F-sharp in the triplum and from F-natural to E-flat in the tenor, as well as the rather long tritones between the C-natural of the cantus and the F-sharp of the contratenor and triplum. Similar progressions can include direct augmented unisons or octaves between the descending tenor and the voice or voices ascending towards the fifth. In this instance, such a clash is only avoided by the unusually long leading tone of the triplum. A more regular approach (three dotted quarter-notes using the same pitches) would also have been acceptable here, resulting in a protracted E-flat/E-natural clash with the tenor.

A sub-set of adjustments which depend on reactions to harmonic context involve the choice between different setting-sizes or voice-identities for a single work. It is clear that as audio queues are newly given, changed or omitted, the behavior of the stable voices can also be altered. Specific examples are discussed also in the section dedicated to these changes, as well as in relation to motivic addition of ficta, and voice function and cadential progressions.
