The Kakapo Green (named after a New Zealand native flightless parrot) is a handcrafted tuneable version of my popular PVC Kakapo low-C penny whistle in the key of C major. The tuning slide is for fine tuning and allows the pitch to be shifted about 30 cents each way.
This is a big whistle and is not recommended for beginners. The Kakapo Green features carefully offset tone holes to simplify fingering. With these offsets and use of the 'pipers grip' the Kakapo Green can be played even if you have relatively small hands. NB, the offsets are configured for the conventional hand position, left hand above right hand. If you play right hand above left, get in touch with me and I can arrange to manufacture a Kakapo Green with opposite offsets.
These whistles are tough, made from PVC. They feature a small bell/horn which helps improve the volume of the lower notes of each octave compared to the higher ones. They also have a curved lip against which the air is directed like a classical flute, rather than a straight one, giving a distinctive tone. Each whistle is carefully hand tuned to concert pitch A=440Hz, within the limits of variable air temperature and how hard you blow.
The range of the Kakapo Green is two octaves, C4 to B6, and maybe a couple of notes higher although they are rather loud! Besides the key of C, the whistle is easily played in Dorian mode (the scale starting on D), in F by half-holing the B and of course Am. My whistle has a very comfortable mouthpiece shape compared to many PVC or aluminium whistles and all feature the Takahe emblem of my Takahe Flutes brand. They are shipped in a triangular package which is very strong. A demo of the basic Kakapo whistle by Eamon Spillane is on YouTube here: https://www.youtube.com/watch?v=8VTywPCNgrk&feature=youtu.be
