Step 3Determine the bore dimensions
The first step is to figure out what shape of bore you want to build. In general, you want a small enough mouthpiece that you can play easily (1.25" to 1.5" diameter or so), and a gradual taper towards the end.
You can use my DidjImp program to help design the bore. You enter the bore dimensions, and then you can see what note that didge will play.
Here are the dimensions for the didge that I will be building in this article. The first column is the distance from the mouthpiece, and the 2nd column is the diameter of the bore at that location.
0m (mouthpiece) - 30mm
.628m - 40mm
1.256m - 60mm
1.78m - 100mm
This didgeridoo should play a "D" (73hz)
