How does it work? Air is blown through the narrow slit of the windway to strike the beveled edge of the next hole, producing sound, then vibrates throughout the inside of the flute. Covering holes lowers the pitch; uncovering them raises it. In fact, the size of the holes is important in setting the pitch: each of the seven holes must be cut and tuned one at a time. Because enlarging a hole raises its pitch, each hole must start small and be enlarged until the desired pitch is achieved. Fingering chart is included.
