Measuring 22 7/8" in length, with a 7/8" diameter sound chamber and four direction holes, this unsplit English Walnut (Juglans regia) branch flute has been accurately tuned and voiced with a clear soulful sound, to a 6 holed F# minor pentatonic scale, playing 3 upper octave notes, with a controlable warble on the fundamental.  Most of  of the bark has been left on, except at the tone holes , the thinckness there taken down to decrease the depth of the tone holes.  Bark fissures and knot holes have been inlayed with crushe Serpentine stone, and the whole branch flute has been finely finished and sealed, insuring that the bark will remain tight to the wood grain over the long life fo the flute.   As an aid against wet-out, 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 Serpentine and brass beads holds the bird to the nest.  The branch for this flute was sustainably gathered, with respect and gratitude, along San Marcos Creek, in San Diego County, California, amongst a wild grove of English Walnut trees.
