OK, this is my problem..
I'm wrighting my first opera, and it is based on a traditional Australian-Aborigional dreamtime story, and as it is based around traditonal aboriginal themse and characters, i found it fitting to have native aborigional instruments aswell. So, 'Didgeridoo' crept its way into my score, BUT, my one porblem with this fantastic idea is..... I don't know how to notate it

. This is porbably a very hard question:
HOW DO I NOTATE DIDERGIDOO?
And i'm sure very few of you, if any, know how to notate it. But if anyone could give me the slightest bit of help, it would be GREATLY appreciated.
Thanks
