Low-A Pitch Inflation

As an aside, it is clear that the pitch of the bagpipe low A has gradually increased over time.  It is apparently somewhere around 480 Hz currently.  I have my original Regal chanter from the mid-1960s which tunes with low A around 462 Hz.  It simply cannot be made to play at a modern pitch of around 480 Hz.

But let's leave to one side the relatively uninteresting question of the basic pitch of low A.  A more interesting and important question relates to the differences between the bagpipe scale and the Western classical scale in relation to the intervals between the notes.
