[Harp-L] circular breathing

[Captron100@xxxxxxx]

A few years back, there was a thread on circlular breathing, the technique  
didgeridoo and horn players use to enable a note to be held indefinitely.   At 
that time several people sent good instructions on how to practice this  
technique.  One practice technique involved blowing thru a straw into a  glass of 
water.  I saved these instructions, but lost them when my computer  died last 
year.
  I have 3 questions.  Does anyone have any good instructions for  practicing 
circular breathing?  
  Do any of u use this technique to good effect on harp?  A guy  who plays 
bothe didgeridoo & harp told me that it's not effective on harp  because you 
need some inherent resistance, which is provided by the didgeridoo  but not a 
harp. 
  Are there any examples of this technique we can listen to, even if  not on 
harp?
