In general, higher (shorter) flutes are more responsive, and easier to play, requiring less breath control. The bore length is typically shorter and smaller in diameter, the amplitude is higher, and the air has less distance to travel down the second chamber. Higher flutes tend to have a brighter sound and are very "forgiving."
Lower (longer) flutes require more breath control and more finesse to play. The bore length is usually longer and larger in diameter, and the amplitude is lower, as the air has a greater distance to travel down the second chamber. Lower flutes are usually perceived to be more melodic and tend to have a more "moody" quality.
* There are slight variations in flute construction, depending on whether the Air Channel is cut into the block,
bird, fetish, or saddle (as is typical in Plains flutes); the Air Channel is cut into the body of the flute (as is
typical in Woodlands flutes); or the Air Channel is formed within the Nest or Spacer. The above diagram
represents general construction of most Native American Flutes.
