Here I was, wondering about the Piobaireach high G. I was under the impression that the Piobaireachd high G was the 16/9 ratio to the fundamental coming in at ~4 cents flat of equal temperament. However, when I tuned my chanter as such (it would barely get sharp enough), it sounded pretty bad. However, Hugh MacCallum’s on his World’s Greatest Pipers album is awesome at the 4 cents flat tuning. So, I tuned the Piobaireachd high G by ear instead and found it tunes just where the light music high G tunes at ~31 cents flat, only it sounds different (sharper to my ear, of course, given my previous misunderstanding). Below you’ll find a mp3 of the normal high G followed by a Piobaireachd high G and also a fourier analysis of the time domain signal normalized to the fundamental high G note. Note the Piobaireachd high G is in red and the light music in green; and because their spectra overlapped exactly (proving they both tune at ~31 cents flat) I had to offset the light music one (green) up 20 Hz to make it easier to see their relative ratios.
