[Harp-L] vibrato and effects

["Docta Funk" <dustin@xxxxxxxxxxxxxx>]

There are some effects on the harp I am interested in learning more about and am not sure where to start...

Anybody have any good tips on vibrato sounds?  Trying to conquer a "wooowa wooowa wowwowa" sound.  Three or two draw seems to be the hole(S).  The best example in harp songs I can name would be toward the middle/end of "Juicy Harmonica." (slamming song by the way)  I have this info from the diatonic harp reference, but still am having trouble getting where I'd like to be.
A good way to get the feel of throat vibrato is to try put vibrato or even tremolo on the 3 draw 1/2 step (or even less) bend. Your throat is involved getting the bend initially, so there's some feel there before you go for the vibrato.  Breathing from the diaphragm will help control the vibrato.  There's always an interaction between the throat and diaphragm when doing a vibrato, since each is involved in controlling the air stream.  For throat vibrato, obviously the emphasis is on the throat--but you'll probably notice some involvement of the diaphragm as well.  As you pulse the diaphragm for tremolo on this note, the change in playing pressure coupled with the throat pulling the bend will tend to add a pitch fluctuation vibrato to the diaphragm tremolo. 
Try playing the 3 draw 1/2 step bend amplified, but play softly.  Practice very soft draw bends.  At some point you'll notice what feels like a direct connection between your throat and the note.  Every little nuance of throat motion will be reflected in the sound.  Work on playing softly, with good note formation and support from your diaphragm.  Then put some vibrato on the note by pulsing the air stream with your throat.  The pitch will change up and down because you've got a hold of the bend with your throat.  Keep at it, it's worth it! 

While down at that end of the harp, how about a deep growl out of the 3 and 2 draws.  Anyone have any tips on getting a raw junior wells-esque draw out of these notes? Is there a technique involved where both the holes are played together?

Or how a clickty clicka sound that would resemble a washboard or almost a rap-DJ sound "chicka", also played at the bottom end of the harp.  I see local harp player(NOLA) Andy J. Forest do this alot.

How do you choke a reed and what does that sound like? ???

Thanks for any help
