bow
Enable an AI agent to recognise a musical instrument bow, assess its playing condition and compatibility, and decide whether it can be used, adjusted, stored or referred for repair.
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 musical instrument bow, assess its playing condition and compatibility, and decide whether it can be used, adjusted, stored or referred for repair.
It can be Identify the bow's design and propose an instrument pairing for confirmation.; Inspect and document the stick, head, contact material and fitted adjustment mechanism.; Adjust working tension where the design, condition and available instructions permit.; Prepare the contact surface using a documented method appropriate to its material.; Compare playing response on a specified instrument under recorded test conditions.; Withdraw a damaged bow from use, arrange specialist service or prepare it for supported storage..
Distinguishing features
Check whether the implement is intended to excite another instrument's strings through a drawn contact surface; a curved outline alone does not establish musical-bow identity.
Distinguish it from an archery bow by the intended string-contact action rather than a projectile draw-and-release function.
Distinguish it from a musical bow instrument by whether another instrument supplies the strings being sounded.
Distinguish it from a plectrum or beater by its extended drawing contact rather than a primarily plucking or striking contact.
Distinguish a complete but unserviceable bow from loose bow components by evidence of the original assembly and missing parts; missing hair alone should not erase its identity.
Scope
+ Bow type, intended instrument family and supported playing configuration
+ Stick, head, hair or alternative contact material, grip and fitted tensioning components
+ Dimensions, mass, balance and deformation under documented conditions
+ Hair engagement, adjustment behaviour and observed playing response
+ Damage, component replacements and requirements for care or specialist intervention
- Archery bows, projectiles and shooting equipment
- Musical bows that are themselves stringed instruments
- The played instrument's body, strings, tuning and independent condition
- The performer's skill, repertoire and interpretation
- Rosin products, spare hair and carrying cases as independently managed objects
- Ownership transactions, insurance valuation and material trade regulations
Characteristics
- Intended instrument association
- Instrument family or specific instrument reference; intended, tested or uncertain Separates documented compatibility from resemblance or an untested pairing.
- Bow construction type
- Documented tradition or design; modern, historical, experimental or unidentified Determines which components and adjustment expectations apply.
- Stick material
- Identified wood, composite, other or unknown, with identification evidence Supports appropriate inspection and intervention without inferring material from appearance alone.
- Overall and usable contact lengths
- mm, with endpoints and adjustment state recorded Supports instrument matching and identifies the available working stroke.
- Mass
- g, with fitted components recorded Provides a reproducible handling characteristic and a baseline after component changes.
- Balance point
- mm from a named reference point, with assembly and adjustment state recorded Helps compare handling without reducing suitability to mass alone.
- Stick curvature and lateral alignment
- Profile or offsets in mm under specified unloaded and permitted working conditions Allows intended curvature to be distinguished from a suspected change or deformation.
- Contact material condition
- Intact, uneven, sparse, contaminated, detached, absent or unassessed; observations may coexist Guides whether poor engagement needs preparation, replacement or further diagnosis.
- Tension control configuration
- Screw-adjusted, manually controlled, fixed or other documented mechanism Prevents an agent from assuming every bow has a screw or movable frog.
- Structural serviceability
- Unassessed, usable within stated limits, specialist inspection required or withdrawn from use Connects inspection evidence to an explicit action decision.
- Component and repair attribution
- Component linked to maker evidence, replacement event or repair record; attribution confidence stated Avoids treating the maker of one component as the verified maker of the entire bow.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.
Bow identity and fit Establishes what musical bow is present and which playing configurations it supports.
The name bow is ambiguous, and musical bows cannot be matched to instruments from shape alone.
Musical bow boundary
Identifies the implement by its intended interaction with an instrument.
Sounding role
Record the evidence that this object is a bow for sounding another instrument, including incomplete or damaged examples.
- What evidence identifies this object as an implement drawn across another instrument's strings? definition
- Is this an individual bow, a detached component, or a musical bow instrument requiring a neighbouring model? boundary
Instrument and grip fit
Records intended instrument association and the handling configuration required by the bow.
Supported playing configuration
Separate maker or tradition-based intended use from pairings confirmed through observation.
- Which instrument family, size and grip configuration is this bow documented as supporting? provenance
- What fit or handling checks must be satisfied before using it with the proposed instrument? action
Stick and component assembly Describes the bow's load-bearing form and the identity of its fitted parts.
Interpreting curvature, damage and repair options requires the actual assembly rather than an assumed standard violin-bow design.
Stick geometry
Captures material evidence and the stick's shape under stated conditions.
Material and shape baseline
Record material confidence, length, section and curvature without treating all departures from straightness as defects.
- What evidence supports the stick's material identification and intended curvature? provenance
- What are its length, section dimensions and lateral alignment at the documented adjustment state? measurement
Fitted parts and attribution
Identifies head fittings, frog where present, grip and adjustment parts as an assembled object.
Assembly continuity
Record which parts are present, secure, replaced or uncertain in origin.
- Which head, heel or frog, grip and adjustment components are fitted, absent or replaced? definition
- Which marks, records or examinations support the attribution of the stick and each potentially substituted component? provenance
Contact material and tension Records the working contact surface and how its tension is established and retained.
A bow may remain recognisable while its hair, anchorage or adjustment system makes it unusable.
String-contact surface
Describes the installed hair or alternative material and its preparation.
Contact surface readiness
Record contact material, distribution, contamination and treatment separately from stick condition.
- What contact material is fitted, and where are strands or contact areas missing, uneven or contaminated? definition
- What evidence supports applying rosin, cleaning or replacing this particular contact material? action
Tension and anchorage
Captures the applicable adjustment method and the security of contact-material attachment.
Working adjustment envelope
Record permitted adjustment behaviour, working clearance and anchorage concerns without inventing a universal tension target.
- How is tension established on this design, and what observations indicate its permitted working setting? definition
- Does adjustment expose slipping attachments, binding parts, exhausted travel or unexpected stick deformation that requires stopping? action
Handling and playing response Relates measurable handling properties to observed performance in a specified playing setup.
Bow suitability depends on the instrument, player and test conditions; tonal judgements alone cannot establish an intrinsic bow property.
Mass and balance
Captures reproducible handling measurements for the assembled bow.
Handling baseline
Record mass and balance with explicit reference points and configuration.
- What are the assembled mass and balance-point distance from a named reference point? measurement
- Which fitted parts and tension state were present during measurement, and have these changed? provenance
Controlled playing observations
Records response without attributing all sound or handling differences to the bow.
Response in context
Capture attack, sustained contact and controllability together with the instrument, player, preparation and tested strokes.
- Under which instrument, string, tension, preparation and player conditions were response observations made? provenance
- What comparison would distinguish a bow-related response problem from an instrument, preparation or technique issue? boundary
Condition and bow care Connects bow-specific inspection findings to use restrictions, service and storage.
Structural integrity and maintenance needs must govern whether playing or adjustment can proceed.
Structural use decision
Assesses the stick, head and attachment regions before further loading.
Damage and use limits
Record cracks, distortion, loose fittings and previous repairs with their location and assessment status.
- Where are cracks, splits, distortion, loose fittings or previous repairs visible, and how were they assessed? measurement
- Which observed defects require withholding tension or playing until a bow specialist has assessed them? action
Service and storage
Defines the next care action for this construction and condition.
Care plan and return to use
Record applicable storage tension, support, service needs and evidence required after intervention.
- What documented instructions govern tension release, handling and case support for this bow? action
- After rehairing, component replacement or structural repair, what inspection and playing checks are required before return to use? action
What the second pass must settle
- Does the registry intend Q204948 to include every regional and historical musical-bow construction, including designs without a frog or screw, and bows with alternative contact materials?
- Which documented measurement methods allow useful comparison of curvature, stiffness and balance across bow designs without imposing one tradition's expectations?
- What design-specific evidence defines permitted working adjustment and reliable stop-use criteria for damaged or previously repaired bows?
- Which specialist or maker instructions support contact-material preparation, cleaning, rehairing and storage for each included construction?
- Does an existing Vercy world model already own musical bows or a materially overlapping concept, requiring this registry entry to link to that publication?
