This instrument is a horn (labrophone) based off the traditional Maori instrument the Putorino.

The traditional Putorino is an interesting case study of an instrument. There are multiple playing techniques that use the instruments body in a variety of ways. Most commonly the instrument is used as an edge blown flute, but there is an advanced technique that also uses it as a labrophone. When this technique is performed the singular hole located about half way down the length of the instrument is used as an enharmonic modifier. I have adapted the second part, the use of a large hole as an enharmonic modifier on a labrophone, as the bases of this instrument. The instrument is far longer with a narrower bore then the bore of a Putorino, and does not have the characteristic reversing of the cone bore like the Purotino has. Instead I have opted to have a large bulbous bell like those found on English horns. The end bell on this instrument is entirely enclosed, forcing any standing waves that form in the bell end to return to the larger finger holes. Sound in manipulated by opening and closing the palm and fingers of the hand over the holes. Pitch is changed primarily by the lips with a minor amount of pitch bend capable of being caused by opening and closing the tone holes. When played this instrument has an unstable tonal center and produces a voice like warbling. The alterations of the enharmonics of the instrument result in a sound character similar to shifting vowels in the mouth.
