This was performed on a small bamboo fife which I constructed some 30+ years ago. It is modeled after a bamboo that I then owned made in India. The Indian flutes have very thin walls and create the sound that is most appealing to me.
I acquired a length of thin bamboo and made this one.
The little melody was inspired by Baka (Pygmy) music I was listening to in preparation for writing music for a National Geographic Television documentary about the Lowland Gorillas of the Congo.
This melody is an example of something simple that is complete and needs no additions, no harmonization, or orchestration.
