Octave Tuning

[Richard Brekne]

Not with the stupid bit...grin..

couple of easy ways of checking this.  Ghosting... hold both notes of 
the octave down (dont play... just hold them down) then play sharply the 
next octave up.  That notes fundemental is coincident with the 4:2 pair 
for the two notes you are holding down.  Example... hold C3 and C4 and 
bang C5.

Then there is the usual third/tenth beat rate test.   Example... play C3 
and Ab2 and compare the 5:4 beat rate with the 5:2 generated when you 
play C4 and Ab2.

Get the book "On Pitch" by Rick Baldersin... and pugg your tuning 
theory.  Tuning life becomes much more interesting and easy when you 
have a good grasp of tuning theory basics. Keep at it !

Cheers
