sorry, that I missed your post on May 24. So, Nicholas, I'm thankful that you quoted the respecting chapter causing my interest.

"When I was a young man" as "Five-taker" Dave Brubeck uses to say, I belonged to the generation in Germany which welcomed the big band sound of the swing period like a drug against the traumatic nazi nightmare.
It was that time I bought my first chromatic and after having been familiar with this strange slide, I started to reproduce all these fascinating big band effects the German youngsters were so delighted about.
I mean eg. this trombone effect caused by moving pots there and back, you understand what I mean. And then, this snoring trumpets, hey, hey.
Well, the harp family loves their babies not at last because of their versatility in producing all kinds of sound & playing variations: TB, puckering, bending, overblow, vibrato, tremolo etc. ect.
Now, as we all know it's hard to teach anybody else all these technics by "linguistic information" only. So, I never heard that somebody has learned how to whistle by the mere instruction how that works.
So, if the learning effect of the doityourself method needed a superfluous example, harp-L would be a good one.
In the same way, I'll never forget my "Eureka" (Hi, Ken) when I successfully bended my first note. Hey, hey, Harpie said to me, you heard that? It really works.
However, I didn't succeed to produce this trumpet snoring on harp till now.
So, Winslow, you may give me some general hints only. I know that I finally have to teach myself.
