Directly above are two Whitepath bamboo flutes.
The top one with no spirit holes, the bottom
one with spirit holes. These holes at the front,
or foot of wood or bamboo flutes are also
sometimes refered to as "direction" holes, alowing
the sound to come out to the four cardinal directions
of North, South, East and West. They also may be
refered to as "tuning" holes, which is there purpose
as they determine the "tonic", or key note of the flute.
