In reed instruments, the vibration is set up when the flow of air from the player’s lungs is converted into a series of air-puffs as the reed rapidly snaps open and shut over the mouthpiece opening. Another way to create such an open-and-shut mechanism involves stretching a light, stretchy membrane over the opening in such a way that the blown air is forced to squeeze under rim of the membrane to enter the tube. Several membrane reed instruments appear in this collection. This version is a set of long tubes each of which makes one note, to be played by several players in hocketing style.
In the audio clip, a set of honking memreeds are joined by several other instruments in the tune “Use Me” by Bill Withers. The melody is played on scraper flute.
