>Now that I look at how the flute/cylindrical tube end correction
again, I see the form in which it was given matches the form that you
presented the end correction for notes with open tone holes; just the
end correction is given, so if I understand correctly, the end
correction is added to the length of the tube. =

Yes. And the advamtage is that you can go back up to a cylindrical part of
the tube before the flare.

>In the case of the
whole flute, it is the full length (L) from top to bottom plus 0.6 *
radius (a). =

Yes.

>Whereas in the case of the tube with open tone holes, I
assume, the length from the mouthpiece tip to the open tone hole
counts as L which is added to the end correction C, noted in the
previous email.

Yes.
