Measuring 20 5/8" in length, with four tuning holes, this unsplit Coast Redwood (Sequoia sempervirens ) branch flute is sweetly and accurately tuned to a G minor pentatonic scale, playing 3 upper octave notes.  Much of the characteristic red bark has been left on, contrasting beautifully with the exposed and finely finished wood grain.  All knot holes have been inlaid with crushed turquoise.   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 turquoise and red horn bone beads holds the bird to the nest, while covering the drain hole.
