The Patriotic Panpipes look to be something spectacular, but in reality it is composed of nothing more than PVC piping and some corks. Now leaving the PVC piping plain would just be boring. Therefore I covered each pipe with red, white, or blue construction paper. I attached the paper with glue stick. From there I made eight holes in a bar of Styrofoam. The Styrofoam bar is used to keep each of the tubes in its proper place, and with a little bit of hot glue keeps the tubes from sliding around as well.
The instrument itself makes sound by blowing air over the tops of the tube. The vibrations inside the tube are what make the sound, hence why the corks are at the bottom to stop the air from completely going through the tube. Each tube is a different length to create different pitches. The reason this happens is because the shorter the length of the tube gets the faster vibrations that occur, causing a higher pitch. Where as the longer the tube the slower vibrations, causing a lower pitch.
Volume control with the Patriotic Panpipes is, the harder you blow air into the tube, the louder the sound is. And just the opposite, the softer you blow air into the tube, the quieter the sound gets.
The vibrations within the tube are the resonance, as they aid in making the pitches through the amplification of sound with air columns (the tubes).
When all of these factors are put together its timbre is airy and somewhat muddied. The Patriotic Panpipes are in the key of C so you can play many songs with it. These Panpipes were enjoyable to make and are entertaining to play with.
