sonata
Enable an agent to recognise a sonata as a musical work, assess its identity and musical completeness, and identify suitable expressions and permitted uses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an agent to recognise a sonata as a musical work, assess its identity and musical completeness, and identify suitable expressions and permitted uses.
A sonata is an instrumental composition whose meaning varies historically, most commonly a work in several contrasting movements for a solo instrument or a solo instrument with keyboard accompaniment.
It can be Resolve a sonata title or catalogue reference to a work while retaining competing identifications.; Match score movements and recording tracks to the sonata's documented movement sequence.; Select a scoring and edition suitable for the available performers and instruments.; Compare revisions or arrangements and expose differences relevant to rehearsal and performance.; Flag missing movements, uncertain attribution or later completion before presenting an expression as complete.; Identify the work, edition and recording evidence needed to assess a requested performance, reproduction or reuse..
Distinguishing features
A sonata attribution requires title, catalogue or contextual evidence; detecting sonata form in a movement is insufficient.
A movement using sonata form can belong to another genre, while a work identified as a sonata need not use that form in every movement.
Movement count, instrumentation and duration support identification but are not individually decisive genre tests.
A sonatina designation must be recorded as evidence rather than automatically converted into sonata or distinguished by a fixed duration threshold.
The sonata as a work persists across linked scores and performances; an edition, recording or individual movement is not automatically the whole work.
Scope
+ Evidence for identifying a musical work as a sonata
+ Composer attribution, titles and work-level catalogue identifiers
+ Movement sequence, internal organisation and completeness
+ Intended instruments, ensemble roles and alternative scorings
+ Relationships to revisions, arrangements, score editions and recorded performances
+ Evidence needed to select an expression and assess a proposed use
- Sonata form as an independently modelled compositional structure
- General music-theory accounts of harmony, rhythm and thematic development
- Publication production and inventory management for score editions and copies
- Recording production, audio encoding and distribution
- Instrument construction and performer biographies
- General copyright rules and jurisdiction-specific legal determinations
Characteristics
- Sonata attribution
- explicitly designated; catalogued as sonata; contextually attributed; disputed; unresolved Makes the basis for genre recognition visible without treating musical form as sufficient proof.
- Work identification
- Links to composer authority records, thematic catalogues, opus designations and documented title variants Distinguishes works with similar titles, numbering or keys.
- Performing forces
- Documented instruments, player counts, ensemble roles and scoring alternatives Determines performance suitability and helps distinguish original scoring from arrangement.
- Movement organisation
- Ordered movement identities with headings, boundaries and version-specific membership Supports whole-work recognition, movement matching and completeness assessment.
- Tonal designation
- Documented work-level key or tonal description; absent; disputed; not applicable Supports identification while avoiding the assumption that every sonata has a single governing key.
- Musical completeness
- complete; unfinished; fragmentary survival; externally completed; unresolved Separates an unfinished composition from missing source material or a later completion.
- Expression relationship
- Links to documented revisions, arrangements, editions, performances and recordings with relationship evidence Prevents different musical texts or scorings from being silently treated as interchangeable.
- Performance duration
- Minutes or seconds, tied to a specified performance or estimate and repeat choices Supports programming without treating one recording's duration as an invariant of the work.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 24 questions.
Sonata identity Establishes which musical work is being described and why it belongs under sonata.
Titles, numbering and structural similarities can otherwise produce false identifications.
Genre evidence
Records the basis and limits of the sonata designation.
Sonata designation
Retain the documented designation and its context independently of movement-level formal analysis.
- Which title source, catalogue entry or scholarly account identifies this work as a sonata? provenance
- Does the designation refer to the whole work, an individual movement, or an analyst's description of form? boundary
Work disambiguation
Separates the work from similarly named sonatas and inconsistent numbering systems.
Catalogue and attribution
Connect title variants, composer attribution and catalogue references without assuming a number or nickname is unique.
- Which combination of attribution, catalogue identifier, scoring and musical incipit distinguishes this sonata? definition
- Which sources explain conflicting sonata numbers, titles or composer attributions? provenance
Movement architecture Describes the sonata's constituent movements and their musical relationships.
An agent needs to recognise the whole work without imposing a fixed movement count or universal sonata-form template.
Movement membership
Identifies the movements, their order and any disputed or version-dependent boundaries.
Movement sequence
Record movement identities separately from score page divisions and recording track divisions.
- What movement sequence and headings are documented for the selected version? definition
- Do continuous sections, omitted movements or track divisions create ambiguity about movement boundaries? boundary
Musical organisation
Captures supported accounts of form, tonal relationships and recurring material.
Movement form and links
Keep analytical claims attributable, including uncertainty about sonata form and relationships between movements.
- Which movements have supported formal analyses, and where do those analyses disagree? provenance
- What tonal, thematic or transitional relationships help explain how these movements constitute this sonata? definition
Scoring and realisation Connects the sonata's performing requirements to a specific playable expression.
Instrument labels alone may conceal alternative scorings, ensemble roles and editorial realisations that affect performance.
Instrumental requirements
Records the documented forces and the status of scoring alternatives.
Forces and roles
Identify required instruments and roles, distinguishing source-supported alternatives from later substitutions.
- Which instruments, player counts and ensemble roles does the selected source specify? definition
- Is an alternative instrument or accompaniment documented for this version, or does it require an arrangement? boundary
Performance choices
Makes consequential realisation and timing choices explicit.
Playable expression
Link performance planning to the chosen score, including repeats, cuts and any required realisation.
- Does this score require a continuo realisation, editorial supplementation or another preparation before rehearsal? action
- What duration is supported for the selected movement sequence, repeat policy and performance approach? measurement
Text history and use Tracks the sonata's surviving musical text, versions and expressions relevant to a proposed use.
A complete score, a reconstructed text and a recording can represent different evidence and different permissions for the same sonata.
Version and completeness
Distinguishes authorial states, source loss, editorial intervention and later completion.
Textual state
Assess completeness against a stated version and retain the provenance of reconstructed or added music.
- Is the sonata unfinished, incompletely preserved, or complete in a version different from the selected score? boundary
- Which sources identify revisions, reconstructed passages or music supplied by a later completer? provenance
Expression selection and permissions
Links the intended use to the actual musical text, publication or recording involved.
Use-specific expression
Keep work identity distinct from the edition or recording selected for performance, reproduction or reuse.
- Which version, arrangement, score edition or recording matches the requested use and movement coverage? action
- What rights or licence evidence applies to the composition and the particular edition or recording being used? provenance
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

Failure modes and hazards
Recalled without web access and unsourced; every item is a lead to verify.
- Confusing the sonata genre with sonata form, which is a way of organizing an individual movement and also occurs in other genres.

- Assuming every sonata has three or four movements or begins with a movement in sonata form.
- Misidentifying works through an opus number or generic title without the composer and catalogue context.
- Assuming that the copyright status of a composition also determines the status of an edition, arrangement or recording.
- Which of these failure modes and hazards hold for the sense of sonata this model covers, and on what evidence? provenance
Regional variation
Recalled without web access and unsourced; every item is a lead to verify.
- Italian Baroque usage distinguished sonata da chiesa and sonata da camera, although their musical features could overlap.
- German-speaking Classical and Romantic traditions made the keyboard sonata and the sonata for instrument and piano prominent models of the genre.
- French Baroque repertoire also used the spelling 'sonate'; naming and movement conventions varied across periods and composers.
- Which of these regional variation hold for the sense of sonata this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Sonata form - A formal organization typically involving exposition, development and recapitulation, rather than a genre of complete composition.
- Sonatina - Usually denotes a smaller-scale or less technically demanding sonata, though the distinction is not governed by a fixed threshold.
- Concerto - Typically features one or more soloists in relation to an orchestra or larger ensemble.
- Suite - Typically groups dances or character pieces; historical overlap with the sonata da camera prevents an absolute structural boundary.
- Symphony - In its usual modern sense, a substantial orchestral composition, often using movement structures also found in sonatas.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of sonata this model covers, and on what evidence? provenance
What the second pass must settle
- Which historical and catalogue authorities should establish the boundary of sonata when the title is absent or disputed?
- How should the registry relate sonata to sonatina and historically qualified sonata designations without creating unsupported separate entries?
- What criteria should distinguish a revision or arrangement of a sonata from a separately identified derivative work?
- Which source hierarchy should resolve disagreements over movement order, scoring, attribution and completeness?
- Which existing Vercy music-work, sonata-form and rights models should this model reference to avoid duplicating their responsibilities?
