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 AI agent to recognise a saxophone, assess its playing readiness and determine compatible setup, use and maintenance actions.
A saxophone is a transposing single-reed aerophone with a conical metal (normally brass) bore, a clarinet-type mouthpiece, and an octave key, classed in Hornbostel-Sachs as 422.212 and patented by Adolphe Sax in France in 1846 as a complete family in band (B♭/E♭) and orchestral (C/F) pitches.
It can be Identify the saxophone type and verify its actual pitch and keywork configuration.; Select and fit compatible playing components while checking joint security and freedom of movement.; Assess sealing, key action, response and tuning through documented inspections and playing tests.; Prepare the instrument for playing with suitable support and an explicitly assessed readiness state.; Remove moisture and store or transport the instrument using methods appropriate to its construction.; Localise faults and distinguish routine setup or cleaning from work requiring an instrument repairer..
Distinguishing features
Check for a single reed fitted against a mouthpiece facing; a double-reed assembly or an air jet directed across an edge indicates a different excitation system.
Check for a generally conical bore together with the single-reed mouthpiece; this combination helps distinguish a saxophone from a clarinet.
Check for finger-operated keywork that opens and closes padded tone holes, rather than brass-instrument valves or a pitch-changing slide.
Do not require a curved body or a particular finish: confirm identity through the bore, mouthpiece system and keywork when the instrument is straight or visually unusual.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Identity and configuration Establishes which saxophone is present and which construction variant it represents.
Appearance alone cannot reliably establish saxophone type, pitch or available keywork.
Instrument identification
Connects physical evidence to a saxophone identity.
Saxophone identification evidence
Records the mouthpiece system, bore form and keywork evidence supporting identification.
- What observed combination of reed, mouthpiece, bore and tone-hole controls identifies this instrument as a saxophone? definition
- Which maker markings, model markings or documents support the attribution, and which parts remain uncertain? provenance

- What evidence establishes the family member, nominal pitch and written-to-sounding interval? provenance
- Which lowest and highest keyed notes and additional controls does this example physically provide? boundary
Reed and air-column setup Describes the fitted components through which the player excites the instrument's air column.
Component mismatch or poor assembly can resemble an instrument fault and can prevent reliable playing.
Mouthpiece and reed assembly
Captures the installed reed, mouthpiece and ligature as a working combination.
Reed fit and function
Records fit, alignment, retention and observed reed condition.
- Which mouthpiece, reed and ligature are installed, and what supports their compatibility with each other and this saxophone? provenance

Neck and mouthpiece joints
Examines the interfaces connecting the playing assembly to the body.
Joint security and adjustment
Records neck compatibility, joint sealing and usable mouthpiece adjustment.
- Where a detachable neck is present, does it seat securely and align with the register mechanism without forced assembly? measurement
- Can the mouthpiece be positioned for testing while retaining a secure seal, and what limits further adjustment? action
Keywork and sealing Records how keys, pads and linked mechanisms control the instrument's openings.
Leaks, binding and coordination faults can make notes unreliable even when the body appears intact.
Tone-hole closure
Assesses pad contact and closure at identified tone holes.
Pad sealing evidence
Distinguishes observed or tested leaks from symptoms that merely suggest them.
- Which pads and tone holes were checked, by what method, and where was incomplete closure observed? measurement
- What evidence distinguishes a sealing fault from a reed, setup or player-related response problem? boundary
Linked key motion
Assesses key travel, return and coordinated operation, including register controls.
Keywork coordination
Records sticking, lost motion, unwanted contact and failures of linked keys to act together.
- Which keys fail to move or return freely, or fail to coordinate with their linked keys? measurement
- Does the register mechanism operate as intended for this model across the tested fingerings? measurement
Playing response and tuning Captures repeatable observations of attacks, sustained notes, register changes and pitch.
Playability depends on the assembled instrument under stated conditions, not simply on visible completeness.
Response testing
Locates response problems by note, register and playing condition.
Response test observations
Records tested behaviour while keeping instrument, setup and player effects distinguishable.
- Under what player, reed, mouthpiece and dynamic conditions do attacks, sustained notes or register transitions become unreliable? measurement
- What controlled retest would help distinguish a setup-dependent symptom from a persistent instrument fault? action
Pitch testing
Relates measured sounding pitch to the instrument's intended pitch convention and test conditions.
Tuning pattern

- What pitch deviations were measured by sounding note, using which reference frequency and warm-up conditions? measurement
- How does a documented mouthpiece-position adjustment affect the measured pattern across registers? measurement
Condition, care and readiness Connects physical condition and support arrangements to immediate playing, care and service decisions.
A saxophone's projecting keywork, pads and fitted joints create specific handling and maintenance constraints.
Structural condition
Locates damage and repairs in relation to the bore, tone holes, key supports and joints.
Damage and service boundary
Records condition evidence and identifies when further playing or adjustment should await assessment.
- Where are dents, cracks, corrosion, loose fittings or prior repairs, and what functional effects have actually been demonstrated? measurement
- Which observed faults require an instrument repairer's assessment before further assembly, adjustment or playing? action
Handling and moisture care
Determines appropriate support, moisture removal and protection for this configuration.
Care and use readiness
Combines support compatibility, cleaning access and unresolved faults into a bounded readiness judgement.
- Which strap, harness, stand and case support this saxophone securely without loading vulnerable keywork? action
- What moisture-removal and storage procedure is appropriate to its body, neck and mouthpiece, and which unresolved conditions limit readiness? action
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 by the breadth pass; each item needs checking against its source before it becomes normative.
- The surviving practical family is the B♭/E♭ band chorus; Sax's C/F orchestral chorus is effectively extinct except for the historical C-melody and rare F mezzo-soprano.
- United States: school-band pipeline starts on alto; jazz pedagogy dominates the popular image of the instrument.
- France and Belgium: classical conservatoire tradition (Marcel Mule / Paris school) and Sax's place of invention; Selmer Paris remains a reference professional make.
- German-speaking classical playing: Sigurd Rascher school - darker, wider concept, different mouthpiece and embouchure, sometimes different high-register practice.
- East Asia: large student-instrument manufacture (notably Japan and China) and strong school wind-ensemble culture.
- Straight soprano is preferred in much classical playing; curved soprano is more common in jazz and popular use.
- C-melody saxophones were a North American parlour and dance-band fashion in the 1910s-1920s and are now a specialist/historical type.
- Which of these regional variation hold for the sense of saxophone this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Clarinet - Cylindrical bore that overblows at the twelfth, with a register key; body is usually wood. The saxophone's conical bore overblows at the octave and uses an octave key.
- Sarrusophone - Also a conical metal family associated with Sax, but sounded with a double reed rather than a single-reed mouthpiece.
- Modern tárogató - Single-reed conical woodwind of similar idea, but a wooden body and different keywork and repertoire, not a brass saxophone.
- Bass clarinet - Single reed and overlapping low-register role, but a largely cylindrical bore that overblows at the twelfth; typically an extended low C/B♭ clarinet, not a conical sax.
- Oboe - Double-reed wooden conical instrument; overblows at the octave but with unrelated fingerings, reed, and timbre.
- Trumpet or flugelhorn - Labrosones: sound is made by lip vibration into a cup mouthpiece, with no cane reed and a brass-instrument harmonic series.
- Electronic wind instrument (EWI) - A MIDI or analog controller with saxophone-like fingering; there is no acoustic air column and no reed-coupled bore.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of saxophone this model covers, and on what evidence? provenance

What the second pass must settle
- Which authoritative identification references should establish coverage of uncommon, historical and modified saxophone variants?
- What model-specific evidence is sufficient to approve replacement neck compatibility beyond physical fit?
- Which inspection and playing-test procedures provide repeatable readiness criteria without misattributing player or reed effects to the instrument?
- What manufacturer or repair guidance should define cleaning methods and the boundary between routine care and specialist adjustment for different materials and finishes?
- How should nonstandard pitch conventions, extended keywork and electronic additions be represented while preserving a single saxophone identity?
