A type of tuned "bull-roar-er"

Unlike the conventional...this one is a hollow tube....with an "adjustible (to put it very loosely) plunger" that is manipulated as it is swung over the head. You might also consider it a type of trombone on a rope.

Almost impossible to play - except when stoned at a "burning man" or after years and years of intoxication.

I'm still working on it .... along with a similar... but eight note device.... from Godollo Hungary.

Both require the strength of youth to play - so sorry to say - my day has probably past.

Sincerely,
Gargoyle
