Landini Cadence¶
A late-medieval cadential voice-leading pattern in which the upper voice descends to the note below its goal before leaping up a third, commonly inserting a fifth between an expanding sixth and final octave.
Core Idea¶
The Landini cadence is a voice-leading detour at a medieval close. The upper voice briefly moves below its expected goal and then leaps upward, enriching the standard outward motion from sixth to octave.
Its identity is contrapuntal and contextual rather than a standalone melodic cell. Analysts must identify the cadential final, voice pair, interval path, and rhythmic arrival inside the polyphonic texture.
Scope of Application¶
- Medieval music analysis. Identifies cadential voice-leading in fourteenth- and fifteenth-century repertory.
- Historical performance. Locates phrase articulation and contrapuntal goals.
- Counterpoint pedagogy. Contrasts direct and embellished cadences.
- Source study. Tracks naming, attribution, notation, and distribution.
Clarity¶
Report work and source, date, mode/final, voices, pitch spelling, interval sequence, rhythmic placement, ficta or editorial alterations, surrounding texture, cadential function, and whether 'Landini' denotes attribution or conventional name. Inclusion test: Require a cadential context with the characteristic upper-voice descent below its goal followed by an upward third into the final octave/unison over compatible lower-voice motion. Exclusion test: Exclude any melody containing down-step/up-third motion, the direct sixth-to-octave medieval cadence, a deceptive cadence, and a modern tonal submediant interruption assumed equivalent by chord labels alone. Nearest boundary: The ordinary medieval cadence expands a sixth directly to an octave; the Landini pattern inserts the under-third escape tone before that final arrival. Exit condition: The label should be withheld when voice assignment, interval succession, final, rhythm, or cadential function cannot be established from the source. Common misclassifications: Landini did not necessarily invent the pattern. Any down-step/up-third melody is not the cadence. It is not defined primarily by modern functional-chord labels. Additional inner voices do not erase the two-voice skeleton. Nearest named distinctions: Deceptive cadence: Redirects expected harmonic closure under tonal syntax. Direct medieval cadence: Moves from sixth to octave without the inserted under-third. Escape tone: Is the general melodic ornament, not necessarily the full cadence. Landini chord progression: Is a misleading chordal reduction of a contrapuntal pattern.
Manages Complexity¶
Three notes in one voice encode a relation among two or more voices, modal final, rhythm, editorial pitch choice, and historical style. Modern harmonic shorthand can obscure the original contrapuntal logic.
Abstract Reasoning¶
- Identify a genuine phrase-ending cadence and its final.
- Select the upper and lower voices carrying the main contrapuntal motion.
- Trace the preparation interval, inserted lower neighbor/escape tone, and final octave or unison.
- Check rhythm, notation, ficta, and inner voices.
- Use the historical name without turning it into an invention claim.
Knowledge Transfer¶
The contour can be quoted in later styles, but literal Landini-cadence classification requires the medieval cadential relation. Formal melodic resemblance alone carries only an analogy.
Neighborhood in Abstraction Space¶
Landini Cadence sits in a moderately populated region (47th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
