[Harp-L] Suzuki Pipe Humming PH-20 Tutorial?

[Don Whitener <whitener@xxxxxxxxxx>]

Several years ago, there was mention made on some forum about someone 
writing a booklet or tutorial on how best to play the PH.

For info on the PH, see:
http://www.suzukiharmonica.com/products/pipehumming.htm

Does anyone know if a tutorial was ever completed, or if anything along 
this line has ever been posted on a web site?  I have done quite a bit of 
searching and have found nothing.

Regards,
