Bicycle Pump Flute
A small tutorial article to introduce you to one of my favorite instruments, and very easy to make, I use it a lot on stage for the human beatbox:
The manufacturing can hardly be easier, one hole and it’s done!
For the manufacture you need a bicycle plastic pump (the metal versions is too thin for a good mouthpiece), a drill with 9mm drill bit, a small half-round file and sandpaper.
Drill and use the file on the hole to give it the desired dimensions, it will work also with a simple round hole, but this form allows better sound control. You also have to work inside the hole with the file like this :
I often play on with breaths and beatbox, but the instrument can also play with a flute sound, and you can use the pump hole for a lovely tremolo effect!
