This is an unusual approach. Ordinarily Highland pipe tunes are played on a D whistle, in the key of A, where the Highland pipe scale comes out perfectly:

xxx ooo Low G
xxo ooo Low A
xoo ooo B
ooo ooo C#
oxx xxx D
xxx xxo E
xxx xoo F#
xxx ooo High G
xxo ooo High A

For the tunes to come out in Bb/Eb, as they do on the Highland pipes, you use an Eb whistle. For the tunes to come out in A/D, as they do on Scottish fiddle etc, you use a D whistle.

If you play in the key of A on a Low G whistle, it comes out in A minor with a C natural, not A Mixolydian with C sharp as is does on the Highland pipes.
