The Native American plains flutes we recorded were carved from walnut and cedar, in the keys of D and G minor. They are traditional end-blown 8-hole flutes, with two air chambers joined by a channel covered by an ornate block often called a “bird” or “fetish”. These flutes have a mellower, darker and generally softer sound, yet have the ability to produce powerful trills, overtones and chirps. Finally, we took the source material and contorted it into a broad selection of ambiences, drones, atmospheres, pads, leads and special FX instruments.
