What key is the Great Highland Bagpipe in? The GHB is in keys of A major and B flat major plus, I'd suggest.
Just played out a Piobaireachd on the electric keyboard here in the keys of A major and it sounded pretty good. Then, with the base of my David Naill practice chanter, I plunked out the A major scale while playing it on my chanter (with its three 'sharps') and they were in tune.
So I think my Naill practice chanter is in the key of A major, but I can also blow it harder and make the tones come out sharper (and even produce a B flat major scale).
And I think my pipe chanter for the full GHB is in B flat major (but sometimes even yet sharper, because, I hypothesize, pipers have wanted a brighter sound over the decades :) ... And I hypothesize that both chanters' Cs and Fs are even sharper and at their own unique frequency in piping, too (is all this correct?) ...
And I have a question about the high Gs, per a number of web sites I've read.
(This information about keys and pitch will be helpful for MuseScore - http://musescore.org/ - composing software with bagpipe register, for example ... ).
I found some informational web pages about this, when I 'googled' "What key is the Great Highland Bagpipe in?"
This first one offers the frequency of current GHB notes in Hertz ...
