Measuring 11 3/8" in length, this unsplit English Walnut (Juglans regia) branch flute has been accurately tuned and sweetly voiced to a 6 holed high G minor pentatonic scale, playing 5 upper octave notes, as heard in the sound sample.  Most of the bark has been left on, with touches of yellow lichen preserved on the right side. Knot holes in the bird have been inlaid with crushed malachite.  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.   Elk lacing with malachite and horn bone beads holds the bird to the nest.  The branch for this flute was sustainably gathered, with love, respect and gratitude, along San Marcos Creek, in San Diego County, California, amongst a wild grove of English Walnut trees.
