My Internet went wonky when I tried replying last night. Richard’s second post addresses my main point which is the difference in chanters. When I purchased a set of the common stock/Northumbrian style smallpipes in A, I soon discovered they were a very different instrument and not completely suited for GHB practice. To continue Richard’s point about the cylindrical bore chanter, the holes have a slightly different placement and low A is pitched about 440. I suspect if I used the smallpipes in lieu of the practice chanter, bad habits would follow. My other concern along those lines is that the mouth blown bag takes a very light touch. It is fun for slow airs and dance tunes, but in general I stay away from the band’s parade tunes.
