I play a number of instruments, some self taught, and can confirm that no bagpipe study should be attempted without the aide of a good tutor. There are precious few self taught pipers who can measure up sans the many pitfalls and bad habits that self instruction invariably brings with it.

I also second the sagacity in passing on the Sailkot Pakistan made, Chanter shaped object that you have purchased. Both Gibson and the afore mentioned Dunbar make great Polypenco/Delrin long practice chanters. The Gibson PC reeds are also among the best sounding and playing out there.
