[Harp-L] tongue roll

[SONNYTONE@xxxxxxx]

I hope Mr.Kinsella can help you, but I know Tom Ball and Paul Lamb will back 
me up on this: Sonny Terry used the tongue trill exclusively, where the tip of 
the tongue is tilted up slightly, and the tongue moves from side to side, 
between the two notes, rapidly. The tongue is a muscle that can be trained if it 
starts out too slowly. One can also do it with straight tongue side to side, I 
prefer the tilt up. Tom, you agree?
