Tongue and mounting Describe the wooden vibrating element and the attachment that establishes its working configuration.
Vibrating tongue
Record the material and shape of the element that generates vibration.
Tongue identity and profile
A useful record identifies the installed tongue and measures its profile rather than treating every tongue as interchangeable.
- What evidence identifies the tongue's material, maker and profile? provenance
- What are its length, width profile and thickness profile in millimetres? measurement
Clamp and support
Describe the tongue attachment, soundbody and support as an assembled mechanical arrangement.
Working mounting configuration
Record the clamp boundary and support arrangement so playability observations can be tied to a reproducible setup.
- Where does the clamp restrain the tongue, and how much tongue projects beyond that boundary? measurement
- How should this build be supported so the mounting remains stable and the tongue has clearance during playing? action
Bow and dax control Describe how excitation and movable contact produce the instrument's controllable response.
Tongue excitation
Capture the demonstrated ways of initiating and sustaining tongue vibration.
Bow contact and response
Playing trials should relate the excitation location and technique to the resulting response, with bow preparation recorded.
- Which bow contact locations and stroke directions produce a sustained response on this tongue? action
- What bow, hair preparation and rosin were used in the documented trial? provenance
Dax contact
Describe the dax surface and how its placement changes the tongue's response.
Contact-to-sound map
Treat pitch and timbre control as an observed relationship among dax position, orientation, contact and excitation rather than a fixed keyboard layout.
- Which dax face and orientation are used, and where does it contact the tongue? measurement
- What repeatable changes in pitch or timbre follow movement of the dax under otherwise comparable playing conditions? measurement
Sound response and output Separate the instrument's demonstrated acoustic behaviour from its electrical capture and reproduction.
Playable response
Document repeatable sounds for a stated tongue and playing configuration.
Configuration-specific range
Record demonstrated pitch regions, transitions and unpitched responses without assigning an unsupported universal range.
- Which sustained pitches or pitch regions are reproducible, and under what tongue, mounting and playing conditions? measurement
- Which apparent range limits arise from the setup, performer or measurement method rather than an established instrument limit? boundary
Pickup signal path
Identify how vibration reaches an electrical output and the requirements of the receiving input.
Transducer and input compatibility
Record the installed pickup arrangement and actual connection requirements instead of assuming all builds share wiring or electronics.
- What transducers, connector wiring and onboard electronics are documented for this build? provenance
- Which input, cable and power arrangement is compatible with those components? action
Playability and care Assess defects and maintenance needs at the tongue, clamp, dax and pickup interfaces.
Mechanical readiness
Inspect the parts that carry bowing forces and dax contact before playing.
Tongue and contact condition
Record cracks, splinters, deformation, attachment movement and damaged contact surfaces as observations requiring evaluation.
- Are cracks, splinters, deformation or movement visible at the tongue and its clamped region? measurement
- Which observed defects require stopping a playing trial, refitting the tongue or seeking repair according to the maker's guidance? action
Response troubleshooting
Use controlled comparisons to locate problems in excitation, mounting or electrical capture.
Weak or unwanted sound
A weak output, rattle or squeal needs a recorded diagnostic comparison before it is attributed to a defective tongue or pickup.
- Does the symptom occur acoustically, only through amplification, or only at particular bow and dax positions? boundary
- Which controlled check of bow preparation, mounting, cable or input can isolate the symptom without altering the tongue? action

What it is Filled
A daxophone is an experimental musical instrument invented by Hans Reichel in which a thin wooden tongue clamped at one end is usually bowed and its vibrations amplified through a contact pickup, with pitch and timbre altered by pressing a curved handheld block called a dax against the tongue.
In scope
- The wooden vibrating tongue and its attachment to a supporting soundbody.
- The dax as a movable contact used to influence tongue vibration.
- Bowing and the relationship between excitation, dax contact and audible response.
- Contact-pickup interfaces and the instrument's connection to external amplification.
- Configuration-specific playability, condition and care.
Out of scope
- Bows as independently modelled musical accessories.
- Amplifiers, loudspeakers and recording systems beyond their interface with the instrument.
- Compositions, performances and recordings featuring a daxophone.
- The biography and complete output of its inventor or subsequent makers.
- Generic timber production and woodworking machinery.
Why it exists Filled
Enable an AI agent to recognise a daxophone, assess its playable configuration and condition, and choose suitable setup, playing or maintenance actions.
Distinguishing features Filled
- The principal vibrating element is a wooden tongue anchored at one end, rather than a tensioned string or an air column. [Maker description](https://dfiction.com/daxophone-portfolio/)
- The characteristic playing arrangement combines tongue excitation with a separate curved dax that alters the tongue's vibrating behaviour. [Maker explanation](https://dfiction.com/daxophone/)
- Unlike a musical saw, its characteristic vibrating element is wooden and its pitch control uses dax contact rather than primarily bending a metal blade.
- Unlike a conventional kalimba, its characteristic setup uses bow excitation and movable dax contact rather than an array of separately tuned, plucked tines.
- Voice-like sound alone is insufficient identification: the tongue, mounting and control arrangement must be established.
What robots and AI may and may not do Filled
Must not
- Attribute the instrument or its recordings to the wrong maker or performer.
- Copy and sell recordings or designs in breach of the rights holders' terms.
- Advise wiring amplification in ways that bypass electrical safety.
Only with a human decision
- Publishing recordings or plans that may be under copyright.
May
- Describe the daxophone and its inventor from reputable music sources.
- Help a user record, play or build one for their own use.
Moral aspects Filled
- Experimental instruments depend on credit for their inventors and players.
- Amplified play can damage hearing at high volume.
Who is affected
- Players and builders

- Which departures from the characteristic wooden tongue, separate dax and contact-pickup arrangement remain daxophones rather than neighbouring experimental instruments?
- What measured dimensions and playable ranges are supported across multiple documented builds, and which remain specific to one tongue or performer?
- Which maker instructions establish acceptable clamp force, cleaning methods, storage conditions and criteria for retiring a damaged tongue?
- Are there daxophone-specific standards or certification requirements, or only requirements applying to particular electrical components and intended markets?
