um, if that lot is a "wild stab in the dark", what do you count as
precision? ... on second thoughts don't tell me, I'd never follow it! :-)
Best wishes,

Can someone please tell me if with concert pitch A=440Hz what is the
frequency of A with traditional pitch? If it is that simple!
As with all things wikipedia, I'd take this with a huge pinch of salt,
but it is a starting point:
http://en.wikipedia.org/wiki/Equal_temperament#Calculating_absolute_frequencies
For an equal temperament C scale where A=440Hz:
F = 440*(2^((45-49)/12)) = 349.228Hz
F# = 440*(2^((46-49)/12)) = 369.994Hz
'Traditional' pitch would be somewhere in this range (corresponding to
the G finger on the chanter)
For arguments sake, let's take 20 cents as 'traditional' .. feel free
to pick another value ... 20 cents sharp in this range would be:
(369.994-349.228)*0.2 +349.228 = 353.381Hz
and this gives you the root note of a 'traditional' pitch chanter. You
then plug this frequency back in to the formula as the reference
frequency and it is now the 47th note in the scale (G) and you want
the 49th (A)
Piper's A = 353.381*(2((49-47)/12)) = 396.657Hz
This ignores the fact that the pipes are not usually tuned in exact
equal temperament.. but that would be my wild stab in the dark..
