Kattookihi

Kattookihi is a traditional wind instrument described in fictional and worldbuilding contexts as part of the maritime culture of the archipelago of Kirtu. In many depictions, the term denotes both the instrument and a foundational repertoire associated with coastal communities. The name is typically presented as belonging to the local language, sometimes explained as a reference to sound or sea imagery, though etymologies vary across sources.

The instrument is usually depicted as a small end-blown flute, about 18–22 centimeters long, carved from reed, bamboo, or light hardwood. It commonly features four to six finger holes and a simple flared mouthpiece, sometimes fashioned from clay or bone. The timbre is described as bright and penetrating, well suited to outdoor performance and signaling across water.

Playing practice and repertoire are described as traditional and communal. Kattookihi is often taught within families or apprenticeship groups and used in contexts such as dawn rituals, storytelling, and festival gatherings. The tuning is frequently pentatonic or diatonic, with players adjusting pitch through lip pressure and breath control. Improvisation within a given modal framework is a recurring element in many fictional depictions.

Construction and variation vary by imagined locality. Some versions include decorative elements such as shell inlays or painted motifs. Modern replicas are produced for museums, educational programs, and contemporary performances by world-music ensembles, sometimes incorporating added materials or adaptive tuning.

Cultural significance in the sources where kattookihi appears centers on coastal identity, intergenerational knowledge transfer, and ceremonial life. In popular culture, the instrument is used in novels, games, and soundtracks inspired by maritime traditions, often carrying symbolic associations with sea, memory, and community cohesion.
