The language - as far as I can tell is Arrenerrte (pronounced ARR-unh-duh ~ with a VERY short 'a' sound as in 'apple')

I thought after I wrote that piece that the term 'correct spelling; was probably 'off the chart' - what I meant was the correct accpted spelling by most indigenes' (in English and derived from the way they pronounce it) is didjeridu. BTW - I learned all this from Aboriginals in Alice Springs when I was there and actually took a couple of lessons from them. Lot of fun. Except for the student who tended to 'dribble' and ended up with a pool of drool on the floor at the end of her didj!!!

Never heard the term Yidaki - where is it from?
