After Homemade Instruments Week on the facebook page, here is an article with some PVC pipes instruments!
Percussion on PVC pipes
A classic, long pipes for big bass, easy to tune by changing the length of pipes, guaranteed effect! Despite the percussive gesture, it is indeed an aerophone, the impact vibrates the air column of the pipe.
Depending on the PVC type, it is also possible to strike the wall of the pipe, the impact of the rod on the plastic vibrate the air column, so this is an idiophone / aerophone.
The soft reed instruments have a membrane stretched over the the air column pipe, the system is similar to the car horn and the fog horn, the sound also, a little!
Same principle, here is my own version with drones and foot pump!
