[Harp-L] Tongue Swishing?

[Daniel McKernan <danm11758@xxxxxxxxx>]

As I was practicing to Ultimates Jam Tracks' Slow Blues in A, I noticed
that when I move my tongue rapidly side to side over 2 holes (at 1:50 and
2:00) it kind of sounds like piano keys.  I think it sounds kind of neat
and was wondering if others use this technique much?  I'm mostly a lip
purser but I tried this technique while tongue blocking.  Anyway I hope you
enjoy this little improv I call Slow Moonlight Bluesin'.
