Measuring 22 51/2" in length, this unsplit Coast Redwood (Sequoia sempervirens ) branch flute is voiced with a clear and soulful sound to a concert tuned G minor pentatonic scale, playing 4 upper octave notes and a controllable warble on the fundamental.  Some of the characteristic red bark has been left on, contrasting beautifully with the exposed and finely finished wood grain.  All knot holes and surface checks have been inlaid with crushed malachite, a stone associated with the heart chakra.  To aid against wet-out the bird has been fitted with a redwood heartwood shoe, for its absorption qualities, and a drain hole has been designed into the air chamber.  Deer lacing with red horn bone and malachite beads holds the bird to the nest, while covering the drain hole.
