Measuring 21 1/2" in length, this unsplit Coast Redwood (Sequoia sempervirens ) branch flute is accurately tuned and voiced to a sweet and soulful G# minor pentatonic scale, playing 3 upper octave notes.  The bark has been left on at the north end, morphing to the finely finished wood grain at the south end.  All knot holes and a few surface checks have been inlaid with crushed Malachite stone.   To aid against wet-out (the build-up of breath condensation that can clog the windway of the flute) 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 Malachite and brass beads holds the bird to the nest, while covering the drain hole.
