I have read posts about purring and advice on how to do it, but I have another question.

I can flutter my tongue fine and gargle also, but when I put the call in, it is like there is not enough room to flutter tongue anymore and I can't do it.

Do you have to move the call back farther than normal in your mouth when you do this or say a keyword?

Also, when you gargle, are you making a particular noise or saying a keyword?

I can get a horrible vibrating gargle sound, but thats about it

I can do the fluttering lip thing with decent results but have heard others do it much better

Thanks for any advice in advance...
