Koch’s Six- and Seven-Measure Phrases and Feminine Endings - HCKoch #4

A phrase may exceed four measures without becoming irregular: its length can grow from expansion or from dependent segments.

A six-measure phrase may result when a four-measure model is enlarged through metrical expansion. Rhythmic elements that occupied smaller values are stretched until they fill whole measures, as in Koch’s examples 50–51. The phrase gains space without acquiring entirely new material: its additional length unfolds what was already latent in the shorter design.

Six measures may also form a three-plus-three structure whose halves are both incomplete. Neither three-measure segment stands independently, but together they create one complete phrase. Alternatively, a dependent two-measure opening may precede a self-sufficient four-measure phrase. Because that opening requires what follows, all six measures belong to one structural unit.

A seven-measure phrase can combine motivic continuation with metrical enlargement: a four-measure model first becomes five measures, then two elements expand. More commonly, an incomplete three-measure segment leads into a complete four-measure phrase, producing a three-plus-four design. An eight-measure unit, by contrast, is normally extended or combines two complete phrases.

Koch’s punctuation is heard through accent and harmony, so the final written note need not mark the phrase’s real division.

For Koch, metre is not imposed after pitches have been invented. Certain notes possess internal emphasis from the moment the melody is conceived, and these accents determine its proper barring. The same pitch sequence can therefore require different divisions if its emphasis changes. In phrase-based styles, rhythm and accent belong to the melodic idea itself and establish its musical identity.

A caesura is the perceptible resting point that separates one melodic section from the next. Since division gives its note structural weight, that note should normally fall on the strong part of the measure. Placing it on a weak beat creates a conflict between melodic and metrical emphasis. Koch corrects such passages by shortening or removing notes until punctuation and accent coincide.

Phrase length is counted in simple-measure units. A written measure of compound metre contains two such units, even though the internal bar line is absent. A simple phrase may also appear within compound metre, or the reverse, so notation does not always disclose the underlying count. Confusing metrical units with subdivisions can make an even phrase look irregular and conceal its actual design.

What sounds like a weak-beat close may be only an overhang: the decisive punctuation has already occurred one accent earlier.

The caesura interrupts melodic continuity on a strong beat through a note from an essential triad of the current or approaching key. Its third, fifth, or octave may serve as the caesura note, while the bass clarifies its function and direction. Several harmonisations may be possible, but melody and bass must confirm the same structural resting point—a practical lesson in figured bass.

When weaker notes follow the accented caesura, they create an overhang, or feminine ending. Triad members may follow one another in many combinations, enriched by passing notes or appoggiaturas. These continuations soften punctuation and encourage further motion without relocating the true division. Even when prolonged for one or two measures, the structural close remains on the earlier strong beat.

An apparent weak-beat caesura is acceptable only when the preceding accented note has genuine harmonic stability. In Koch’s example 63, an intervening C demands its own harmony, so D cannot act as the true caesura and G cannot be its feminine continuation. Remove C or make it a clear passing note, and the reading works. A well-designed cadential bass exposes the difference between written ending and structural punctuation.
