Overtone Flute/Whistle Construction
Posted: Wed Oct 27, 2010 7:44 pm
I am interesting in trying to make my own PVC Overtone Flute/Whistle, and am posting this here on C&F with the hopes that some of you with experience making whistles may be able to guide me in the process. Besides, I'm pretty miserable at making things and can use all the advice I can get.
Nadishana has created a "chromatic" overtone flute as seen on this YouTube video:

Obviously, changing the length changes the fundamental pitch. On the video @4:00, he is playing the instrument with no attachments, pitched in "A". It looks to be about 3 feet long in "A", and about 5' long down in the low A# range.
First question: Should the pitch chart (page 3) in this article about creating PVC didgeridoos apply to the closed tube of a low whistle? The lengths seem to correspond with the instrument length on the video at various pitches.

Second question: Should I attempt to make a fipple at the top of the overtone instrument like this video about a fujara? (single hole, not a slot)

OR... should I cut a slot long and cover the slot similar to this video? (It looks like Nadishana has a cover on the top of his instrument)

Last question: What would be the best way to fashion the connector on the bottom for attachments? It looks like there is a coupling on the end. I assume that if the coupling hangs off an inch or two off the main instrument body, that would affect the pitch of the "A" and therefore should be taken into account when making the main pipe? Also, the attachments would have to be slightly longer than anticipated in order to compensate for an inch or two inside the coupling, yes?
OK I lied one more question...
Any idea where I can find the calculations for the chromatic half-steps not on the chart?
