The analysis covers every measure of Op. 95 at the harmonic level — Roman numeral identification, cadence inventory, voice-leading observation, and cross-movement structural argument — for all four movements.
What distinguishes this project from a general analytical survey is its method: every harmonic reading is extracted directly from MusicXML score data and verified at the beat level before being committed to prose. Claims are not made from listening or memory; they are derived from the score as data and then described.
Classical sonata convention is clear about where the second theme should appear. Beethoven disregards it. The analysis traces where the movement actually goes, why the expected destination is bypassed, and how the recapitulation resolves the asymmetry this creates — not by correcting the original departure but by changing the quality of the home key itself.
The development is only 22 measures long. The coda returns the opening gesture in a way that makes the entire movement feel circular — as though it began knowing how it would end.
F minor
Not the expected key
Bare octave, F
D major is the tonal opposite of F minor. The second movement opens there — a solo cello, four bars, no other instruments. What follows is 192 bars of D major that is perpetually shadowed by the flat side: chromatic chords that pull away from the tonic, an extended passage that touches harmonies well beyond any single key, and a final chord that belongs to neither the key that has just concluded nor the key that is about to begin.
The formal structure of this movement has been regularly misidentified in the analytical literature. The analysis argues for a different reading — one determined by which instrument launches each section and in which direction.

Movement III begins on the exact chord that ended Movement II. It is not a coincidence. The analysis identifies that chord — the same four pitches — serving two different harmonic functions in two consecutive movements, the attacca connection transforming meaning rather than merely continuing it.
The movement's formal structure is unusual: the scherzo and trio are distinguished not by key signature but by texture. The key signature changes without disrupting the formal identity of the section it belongs to. Understanding why requires attending to how the music moves rather than how it is notated.

The final movement performs a retrospective act in its opening bars: it takes the bare F octave that ended Movement III and reframes it as a preparation rather than an arrival. What sounded like a conclusion becomes an upbeat. The movement then stages, over 176 bars, the process by which F minor becomes F major.
That conversion is not a brightening at the end — it is argued for across the entire movement, through three ascending chromatic passages and two extended harmonic plateaux that suspend tonal function entirely. The final chord states something that has been withheld for the full length of the quartet.

The analysis is based on the IMSLP22095 OMR scan of Op. 95, processed via Audiveris and corrected at the measure level. All harmonic readings are extracted from MusicXML data at the beat level — every chord identification is verified against the raw pitch data before being committed to prose.
The principal analytical categories are: Roman numeral analysis, cadence identification and classification, voice-leading observation with attention to chromatic events, formal structure, and cross-movement tonal argument. Each movement analysis is maintained as a separate verified document.
A standing rule throughout: no analytical claim is made from memory or inference. If a specific measure is cited, the pitch content of that measure has been extracted and checked. Scan errors in the source have been identified and documented.
This project does not propose a speculative programme for the work or argue from biographical context. It does not treat harmonic analysis as a means to a narrative end. The analysis describes what the music does, not what it means outside itself.
It also does not claim to resolve all ambiguity. Several passages in Op. 95 are genuinely analytically resistant — places where multiple harmonic readings are defensible and the choice between them is a matter of interpretive judgment rather than fact. These are identified and discussed rather than papered over with a confident label.
The analysis is descriptive before it is argumentative. The argumentative layer — the cross-movement structural claims — rests on the descriptive foundation and is available in the analytical guides.
