igil

Combined identification evidence

Record string arrangement, resonator outline, neck interface and bowing configuration as a combined identification case.

1. Which observed features support identifying this instrument as an igil? definition
2. Which features leave it confusable with a morin khuur, byzaanchy or another regional fiddle? boundary

Documented igil attribution

Preserve the exact attributed name and its evidence; do not silently merge related regional names or reject documented variants.

1. Who identified the instrument as an igil, and where is that identification recorded? provenance
2. If the construction departs from the usual form, what evidence establishes it as an igil variant? boundary

Resonator material evidence

Document the actual face material and assembly. Alash describes both wooden and skin-faced igils. [Alash instrument guide](https://alashensemble.com/instruments.htm)

1. Is the resonator face wood, skin or another documented material, and how was this established? provenance
2. What are the body's dimensions and the visible condition of its face and joints? measurement

String path geometry

Record string materials, attachment details, bridge seating and clearances before proposing replacement or adjustment.

1. What material and construction does each string use, and which evidence supports that identification? provenance
2. What are the vibrating lengths, bridge position and clearances along each string path? measurement
3. Which replacement or adjustment specifications have the maker or an experienced igil repairer endorsed? action

Documented tuning target

Record both target pitches and their authority. Alash's Achai notes describe fifth and fourth tunings, so no single interval should be imposed universally. [Achai liner notes](https://www.alashensemble.com/CDs/Achai_liner-notes.pdf)

1. Which open-string pitches and interval does the player or maker specify for this use? provenance
2. What pitches are measured, and how far do they differ from the specified targets? measurement

Bowed response and drift

Record onset, sustained response, unwanted contact and pitch drift without treating every complex tone as a defect.

1. Under which bow, player and tuning conditions were response and pitch stability assessed? provenance
2. Which strings or playing positions exhibit unstable response, unwanted contact or measurable drift? measurement
3. Does practitioner assessment call for technique changes, setup adjustment or repair? action

Supported playing position

Record the demonstrated playing position and any restrictions on bow travel or instrument support.

1. How does the player support this igil without obstructing its strings or loading vulnerable body areas? action
2. Can the associated bow reach the intended strings throughout the demonstrated stroke? measurement

Technique-specific playability

Assess neck access and string response using demonstrated igil technique, with the intended musical role recorded separately.

1. Which string-contact technique does the practitioner demonstrate for this instrument? provenance
2. Do its clearances and response support the demonstrated technique across the required range? measurement
3. What tuning or setup changes, if any, are needed for the intended solo or accompaniment role? action

Load-bearing condition

Assess string attachments, pegs, bridge, neck and resonator for conditions that require restricted use or specialist examination.

1. Are there frayed strings, slipping pegs, displaced supports, cracks or face deformation? measurement
2. Which observed conditions require withholding tuning or playing pending expert assessment? action

Supported care plan

Record approved cleaning, storage, restringing and bow-hair care procedures, distinguishing routine player care from maker or conservator work.

1. Which care instructions are documented for this igil's face, finish, strings and bow hair? provenance
2. Which interventions can the player perform, and which require an igil maker or conservator? action
3. What post-intervention checks establish that bridge position, tuning stability and bowed response are acceptable? action
