I personally find the "tongue flutter" an elusive technique. I'd swear I
hear Little Walter and Sonny Terry using these tongue flutters, but then
again I have difficulty pointing out a specific example. Can anyone shed
some more light on this technique? How many holes are covered with the
tongue? I can't seem to do it with less than 2-3 holes, but I think I hear
it done with only one. I find it nearly impossible to twist my tongue into
the "vertical" orientation that would be required to "flutter" a single
hole. So, I can't do it with only one hole and it doesn't sound right if I
use more than one hole. Also, the motion involved is a bit mysterious.
Gary mentioned the tongue is tilted slightly up and moved side-to-side. Tom
mentioned bouncing it up and down. No one mentioned actually lifting it and
replacing it repeatedly.
Can anyone cite some examples I can study? I don't recall seeing it in your
LW/BW or ST "licks" books, Tom.
