Overtone Flute

July 12th, 2015

Several years ago I got into making pennywhistles out of pvc. My main goal was to get a low whistle without paying hundreds of dollars, but once I figured out the basic principles it was a lot of fun experimenting. I found one of those experiments yesterday and got it out:

That's a 5' overtone flute in A. It's six times the length of a standard D whistle, so the lowest note it can play is two and a half octaves lower, at 110 Hz. The flute is very narrow for its length, though, so it's extremely quiet playing that note and instead is much more at ease when playing overtones.

The available notes are all multiples of the base frequency:
notefrequency
110 HzA
220 HzA
330 HzE
440 HzA
550 HzC#
660 HzE
770 HzG
880 HzA
990 HzB

I'm not very good at playing it, but it sounds like this: mp3.
