Re: [Harp-L] U-blocking



I didn't notice the appended post of Robert Bonfiglio's. I had actually wondered, not being a regular 'U' blocker, whether it was possible to play a 'double block' as Robert mentions here. Have I got this right? To play 'A-D-A', you would have to play the two 'A's respectively out of each corner of the mouth, then use the 'U' channel to select the 'D, blocking the B and the F. Now I'm not bad at tongue blocking and switching, and as I might have mentioned before, have found that I can convert this skill into whistling two-part harmonies as well. But if I try what Robert is talking about, I find that I need the corners of my mouth to support the tongue-channel (or 'U') Does that mean, Robert, that you can curl your tongue to form the channel WITHOUT support at the sides from your mouth??

I find it fun to change up tongue technique as required in mid phrase.  
It is especially helpful if I am playing a rhythm role on the  
diatonic. I'll toss a line played by pucker next to some tongue  
blocked chords and back to tongue, etc.

I haven't u- blocked but I may give that a try too.

I also like to mix tongue shakes into the textural mix to add another  
element.

Mixing up tongue techniques makes it feel like my tongue is sort of  
dancing on the instrument.
