Listen Up! "W" is for Willow Flute
The willow flute is a Nordic folk flute with no finger holes. You play it by varying the amount of air blown into it, and by using a finger to control the hole at the bottom, covering it at times. Modern willow flutes are made from plastic, but originally, they were made from the bark of green willow branches. They could only be made in the spring, and when the bark dried out, they were unplayable.http://www.youtube.com/watch?v=hPJ8NotbjIA
