Measuring 21 1/8" in length, this unsplit English Walnut (Juglans regia) branch flute has been accurately tuned and sweetly voiced to a 6 holed F# minor pentatonic scale, playing 2 upper octave notes, and a controlable warble on the fundamental.  Some of the bark has been left on, sanded smooth and finely finished in a beautifully paterned contrast with the exposed wood grain.  Small knot holes and a few surface checks near the mouth end have been inlayed with crushed Lapis lazuli.   As an 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 shoe, for its absorption qualities, and a drain hole has been designed into the air chamber.  Elk lacing with Lapis lazuli and brass beads holds the bird to the nest.  The branch for this flute was sustainably gathered, with deep respect and gratitude, along San Marcos Creek, in San Diego County, California, amongst a wild grove of English Walnut trees.
