launeddas

Three differentiated pipes

The conventional arrangement combines a holeless tumbu drone with fingered mancosa and mancosedda pipes. Source: [SardegnaTurismo](https://www.sardegnaturismo.it/en/launeddas-others-sardinia-music?language=it).

1. Which present component is the tumbu, which is the mancosa and which is the mancosedda? definition
2. Is this a complete set, a surviving component or a collection whose association remains unverified? boundary

Bound and free pipes

The mancosa and tumbu are joined, while the mancosedda remains separate; this relationship is part of recognition and handling. Source: [SardegnaCultura](https://www.sardegnacultura.it/articolo/le-launeddas).

1. Are the tumbu and mancosa joined securely in their intended relative positions? measurement
2. Does an unusual assembly reflect documented practice, later alteration or an assembly error? provenance

Individual reed generators

A documented construction uses a small cane mouthpiece with a reed tongue cut from its own wall, inserted into each pipe and sealed with beeswax. Source: [SardegnaCultura object record](https://www.sardegnacultura.it/en/search/1f0a1645-24c4-43ff-b081-8c035395eae9).

1. What reed construction, seal material and visible condition are present on each pipe? definition
2. Which reeds are associated with the maker's original set, and which are documented replacements? provenance

Finger holes and arrefinu

The fingered pipes conventionally have four finger holes and a further opening, the arrefinu, whose wax adjustment regulates the fundamental pitch.

1. What are the dimensions and positions of each pipe's finger holes and arrefinu? measurement
2. Which wax deposits are intentional acoustic adjustments rather than dirt or damage? boundary

Named pipe configurations

Documented cuntzertus distinguish configurations within launeddas; retain the source's terminology and verify its application to the particular set. Source: [Iscandula](https://www.launeddas.it/iscandula/launeddas_cuntzertus.php).

1. What cuntzertu name is attributed to this set, and by which maker, player or collection record? provenance
2. Which pipe roles and pitch relationships support or challenge that attribution? definition

Measured set relationships

The model should distinguish measured frequencies, intended intervals and the player or maker's judgement of tuning; numerical tolerances remain to be established.

1. What frequencies occur for the drone and each documented fingering under recorded test conditions? measurement
2. What tuning reference and acceptable interval deviations does the responsible maker or player specify? provenance

Circular breathing interface

Launeddas performance uses circular breathing to sustain sound while the player inhales through the nose. Source: [Muravera tourism](https://www.muraverasardegna.it/it/articles/4/le-launeddas.html).

1. Can an experienced player sustain the three pipes together, and what interruptions or response differences occur? measurement
2. What further assessment would distinguish a reed or sealing problem from difficulty with breath technique? action

Paired hand interface

The conventional hold places the bound pair in the left hand and the separate mancosedda in the right; record the actual set's spacing and any documented adaptation.

1. Can the intended player cover the finger holes while maintaining the required pipe and mouthpiece positions? measurement
2. Does a proposed change to bindings or pipe alignment require a skilled player's assessment before use? action

Component-specific condition

Record cracks, loose bindings, displaced wax and reed defects by component, together with whether their effect on playing has actually been tested.

1. Which pipe bodies, reeds, seals or bindings show visible defects, and where? measurement
2. Does the set's condition and intended use support a playing test or require specialist inspection first? action

Documented component changes

Replacement reeds, altered wax and exchanged pipes should be recorded with their purpose and before-and-after observations; compatibility must be assessed for the actual set.

1. What repairs, reed replacements, wax adjustments or pipe substitutions are documented? provenance
2. Who can assess a proposed intervention, and what playing or preservation outcome should it achieve? action
