Measuring 24" in length, with a 1" diameter sound chamber, this Arroyo Willow (Salix lasiolepis) unsplit branch flute is tuned to a clear and soulful low D# minor pentatonic scale, playing four upper octave notes, as heard in the sound sample.  Tone holes have been ergonomically offset for ease of playng.  Some of the dark underlayer of  bark has been left on, sanded smooth to a fine finish, contrasting nicely with the exposed wood grain.  A few end checks have been inlaid with crushed malachite.  Deer lacing with malachite and brass beads holds the bird to the nest.  To help prevent wet-out, the bird has been fitted with a redwood shoe, and a drain hole, covered by the lacing, has been designed into the bottom of the air chamber.  The branch for this flute was gathered sustainably, with prayer and gratitude, within the San Marcos Creek watershed of California.   California Indians found many uses for the wonderful willow tree, including bows, baskets, shelters, clothing, fish traps and medicines derived from salicin in the willow's bark, the original "aspirin".
