Measuring 24" in length, with four tuning/direction holes, this Arroyo Willow (Salix lasiolepis) unsplit branch flute is clearly voiced to a sweet and soulful F minor pentatonic scale, playing three upper octave notes.  Much of the beautiful dark underlayer of  bark has been left on, sanded smooth to a fine finish, contrasting nicely with the exposed wood grain.  A few small surface checks and knot holes have been inlaid with crushed malachite.  Deer lacing with malachite and horn bone 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 respect 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.
