The Hemisphere (Heaven & Earth Flute) is a double-ended bamboo drone flute that is played with the mouthpiece in the center of the instrument. The drone comes out the upper half while the melody notes come out the lower half. It is hand-made by Oscar La Rosa in Peru.
The tuning of the Heaven & Earth Flute is F Minor Pentatonic Scale. Drones in the lower and higher octave of F are possible on this instrument.
The notes are played from low to high by first covering all the finger holes, then lifting one finger at a time starting with the hole closest to the end of the flute and moving up toward the center of the flute.
