gong
Enable an AI agent to recognise a gong, assess its sounding body and readiness for use, and select actions compatible with its construction, condition and intended role.
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 gong, assess its sounding body and readiness for use, and select actions compatible with its construction, condition and intended role.
It can be Identify and compare a gong using its profile, markings, dimensions and documented identity.; Select a compatible beater and permitted striking region for an intended response.; Suspend or support the gong with suitable attachments and vibration clearance.; Sound and, where permitted, damp the gong under controlled conditions.; Inspect changes in body condition and acoustic response to decide whether use should continue.; Prepare the gong for handling or transport while protecting its body and attachment points..
Distinguishing features
Confirm that the object itself is a vibrating sounding body intended to produce sound when struck; a gong-shaped decoration or electronic playback device does not meet this test.
Inspect for a plate-like or shallow bowl-like body, with or without a central boss, rather than relying on the name alone to distinguish it from a deeper bell.
Check whether its intended use involves striking a supported or suspended body with a separate implement; paired plates intended primarily to clash together suggest cymbals, although playing method alone is not decisive.
Distinguish a bowl-form gong from a singing bowl using documented identification, support arrangement and intended excitation methods together; ambiguous cases require an explicit boundary decision.
Scope
+ The gong's sounding body, profile, material and identifying features
+ Its intended striking regions and compatible striking implements
+ Its suspension or support interfaces and installed clearance
+ Its acoustic response under recorded sounding conditions
+ Damage, alterations and restrictions affecting handling or sounding
- The construction and maintenance of a separate stand or mounting structure
- Mallets and beaters as independently managed objects
- Musical compositions, performance notation and ensemble coordination
- Ceremonies, traditions and cultural permissions beyond their constraints on this gong
- Electronic gong simulations and recordings
- Room acoustics and venue-wide sound management
Characteristics
- Sounding-body profile
- Flat, shallow-curved, bossed, other documented profile, unknown; record rim form separately Helps recognise the gong and locate regions whose support, contact or damage may affect its response.
- Body dimensions and mass
- Diameter or principal spans in mm; depth and thickness at specified locations in mm; mass in kg Supports identification, mounting compatibility and handling decisions without assuming uniform thickness.
- Material identification
- Documented or tested material or alloy, with identification method and confidence; unknown allowed Informs interpretation of condition and treatment options; appearance alone may not establish composition.
- Suspension and support configuration
- Attachment points, cords or fittings, orientation and linked support Determines whether the gong is securely carried and free to vibrate as intended.
- Striking-region guidance
- Documented preferred, permitted and prohibited regions; unknown Makes sounding decisions specific to this gong rather than assuming every surface is suitable.
- Compatible beater
- Linked beater or documented head material, hardness, size and mass constraints Connects the desired response and damage constraints to an actual striking implement.
- Acoustic response
- Prominent frequencies in Hz, decay time in s and sound level in dB with weighting, distance and test conditions stated Allows meaningful comparison of sound across inspections and playing conditions.
- Pitch role
- Specified pitch target, relative ensemble pitch, no fixed pitch requirement, unknown Prevents treating every gong as either a precisely tuned note or an entirely unpitched instrument.
- Body and attachment condition
- Located observations of cracks, deformation, surface change, attachment wear and repairs, with date and severity assessment Supports decisions about sounding, suspension, transport and specialist inspection.
- Use restrictions
- Permitted actions and conditions, restricted actions, authority and unresolved permissions Distinguishes physical capability from authorisation to strike, move, clean or alter this gong.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 4 bundles · 8 layers · 8 findings · 20 questions.
Gong identity and form Establish what this gong is and which physical features support that identification.
Gong names and neighbouring instrument categories can overlap, so recognition must combine documented identity with observed construction.
Identity and boundaries
Locate the individual object within the gong category without forcing uncertain subtype labels.
Gong identification
Record the evidence for identifying this object as a gong and any unresolved overlap with bells, cymbals or singing bowls.
- What physical features and intended sounding method support identifying this object as a gong? definition
- Which maker, collection or practitioner records establish its name and subtype? provenance
- Does its form or use leave a boundary with a bell, cymbal or singing bowl unresolved? boundary
Body construction
Describe the sounding body's geometry, material and visible construction evidence.
Profile and material
Capture dimensions, boss and rim geometry, thickness variation and the basis of material identification.
- What are the body's principal dimensions, mass, boss height if present, rim profile and measured thickness locations? measurement
- What evidence establishes the material and manufacturing method, and which aspects remain unknown? provenance
Striking and acoustic response Connect how the gong is excited with the sound it produces.
A useful gong model must distinguish intended response from a response changed by beater choice, strike position, mounting or condition.
Excitation and damping
Establish suitable contact methods for starting and stopping vibration.
Permitted contact methods
Record supported striking and damping techniques without assuming that all gong-playing techniques suit this object.
- Which striking regions and beater properties are recommended or prohibited for this gong, and by whom? action
- What damping method, if any, is permitted, and which surfaces may be contacted? action
Response and pitch
Describe the gong's sound relative to a reproducible test and its intended musical or signalling role.
Acoustic baseline
Record expected pitch behaviour, attack, sustained sound and decay with enough context to interpret later changes.
- Does this gong have a specified pitch target, a relative pitch role or no fixed pitch requirement? definition
- What frequencies, decay behaviour and sound levels are observed with the beater, strike position, excitation method, mounting and microphone position recorded? measurement
- Which audible changes would justify inspecting the body or mounting before further sounding? action
Support and playing space Model the interfaces that carry the gong and the space required for sounding it.
The support must carry the gong while allowing its intended vibration and any movement produced by striking.
Load-bearing interfaces
Identify how the gong's weight reaches its support and where attachment condition matters.
Suspension or resting support
Record suspension holes, loops or resting contacts and their compatibility with the current installation.
- Which points are intended to carry this gong, and what evidence supports the installed orientation and attachment arrangement? provenance
- Are the gong's attachment points and contacting cords or fittings free from damage or wear that would require unloading it? action
Clearance and contact
Assess unintended contact and available space during playing.
Free-sounding envelope
Describe clearance for the body, its movement and the player's beater path.
- What clearances exist between the gong and its frame, floor and nearby objects at rest and during intended use? measurement
- Which unintended contacts could cause rattling, damping or collision, and what adjustment would remove them? action
Condition and use decisions Connect observed condition and object-specific restrictions to sounding, care and movement decisions.
A gong can remain recognisable while damage, repairs or custodial restrictions make particular actions unsuitable.
Body integrity and change
Track changes in the sounding body and distinguish observations from diagnoses.
Damage and alteration
Locate cracks, dents, deformation, surface changes and repairs, relating them to earlier records where available.
- Where are cracks, deformation, surface changes or repairs, and how have their measured extent and appearance changed? measurement
- Which marks are documented manufacturing or tuning features, and which remain unexplained? provenance
- Which observations require suspending sounding or obtaining specialist assessment before moving or treating the gong? action
Handling, care and permission
Establish the actions allowed for this gong and the conditions under which they may proceed.
Action readiness
Combine care instructions, handling requirements, acoustic conditions and custodial permissions into explicit action constraints.
- What documented handling, packing and cleaning methods protect this gong's profile, surface and attachment points? action
- Who may authorise sounding, relocation, cleaning or alteration, and what object-specific restrictions apply? provenance
- Before sounding, what conditions must be met for mounting security, nearby people and permitted sound exposure? action
What the second pass must settle
- Does the registry intend gong to include bowl-form and friction-excited instruments, and how should overlap with singing bowls be resolved?
- Which documented subtype vocabulary can represent different gong traditions without treating regional names as interchangeable?
- What evidence is sufficient to establish an acoustic baseline when the gong has no maker specification or known undamaged recording?
- Which damage observations and attachment conditions warrant stopping use for each construction type, and which require specialist judgement?
- How should custodial and ceremonial restrictions be recorded when published descriptions do not establish permission to sound or alter the individual gong?
