NAF out of tune

[ThorntonRose]

This NAF has plays the natural scale (322222), plus a few accidentals. It's a little different, but I have been able to noodle out some tunes from my whistle repetoire, such as Suo Gan and The South Wind.

ThortonRose, that exceeds 12 semitones (octave).
Don't you mean 3:2:2:1:2:2 instead?
(my understanding is that is a type of hexatonic scale of many NAF).

NAF out of tune

Aren't they all?

different scale white man!

I've read that the traditional design (or one of them) is equal-sized holes, equally spaced the distance of a thumb-width.

Well, there you go! You're not out of tune, you're traditional!

A "standard" modern 5-hole NAF would have a natural scale of 3:2:2:3:2, or in G: G Bb c d f g. The 6-hole NAF allows a scale M6th 3:2:2:2:1:2, or in G: G Bb c d e f g. Basically a gapped Dorian with the 2nd missing.

Tuning a Bell note/Keynote/Fundamental/Root note, is done by changing the bore end hole diameter. If the note is sharp, reduction of the diameter with "Blu-Tack" or other type putty will flatten the note. The reverse is also true. Quena Makers use this technique on short bore Bamboo to lower the Keynote

Tone holes can be tuned in the same manner. If the holes have been undercut, a little application of putty to reduce the diameter will flatten the note. Rolling a piece of fine grain sandpaper into a "cone shape" can be used to sand/increase the undercut to sharpen the note. SMALL INCREMENTS!!!

If you make a mistake, you can correct an oversized hole with clear laquer/nail polish. You can also make a tuning reduction permanent this way too.
