What is the timbre (instrumentation) of “Origins”?

What will be an ideal response?

• Synthesizer and Native-American flute. Note Figure 2.16, p. 85, in Worlds of Music. This instrument is basically a tube through which the flutist blows air and produces different pitches by covering different holes in the tube with his fingers. By comparison, the familiar metal flute from the Western music-culture has finger holes covered by keypads, and its tone is created by blowing across a hole in the end of the flute.
