The quena is a traditional flute from the Andes. Quenas can be made from bamboo and other natural materials in addition to PVC pipe. PVC panel quenas are durable, waterproof and easy to make and play. In this article, you’ll learn how to make just such a PVC quena in the key of G.
Cut the PVC pipe to 17 inches long. You will shorten it later to tune it to G, but you will want to start with it longer than it will end up.
Drill the holes. It is important that the holes be in precisely the right places for the quena to be in tune, so always measure twice with the precision rule before drilling. Start with the top hole,PVC ceiling positioning it 7.56 inches from the top of the quena. The second hole should be 8.62 inches from the top. The first and second holes should be .44 inch in diameter. The third hole is positioned 25 degrees off to the left (as you look down the quena from the notch) of the center line created by the notch and first two holes.
The third hole should be 9.81 inches from the top of the quena and .38 inch in diameter of PVC ceiling panel. The fourth hole is positioned 11.14 inches from the top and is back on the center line. It should be .25 inch in diameter. The fifth hole is 12.03 inches from the top of the quena and is .47 inch in diameter. It should also be on the center line. The sixth and final hole is 13.25 inches from the top of the quena. It should be .25 inch in diameter and is 25 degrees off to the right (as you look down the quena from the notch) of the center line. Finally, drill a hole .27 inch in diameter in the back 6.87 inches from the top. The illustration here shows these dimensions in a chart created by Dan Bruner.
Blow through the quena with all of the holes covered to PVC wall panel. All of the notes will be flat until you tune them. Set the tuning machine to G. Shorten the quena in small amounts from the end until the sound you make with all of the holes covered matches the G on the tuning machine. Lifting one finger at a time, continue to tune each note, going up the scale. To raise the pitch and bring notes into tune, enlarge the holes a tiny bit at a time using the reamer.
