Re: [Harp-L] Brendan and Suzuki



I have heard from many people that the "locking up" of
reeds is a more or less common problem with Suzuki
reeds. I have no idea about the reason myself. I am
wondering if Suzuki has an idea. 
What I can imagine is that the reed is pushed into the
slot before it would be able to start vibrating.
Vibrations are caused by airflow separation at the
reed and reedslot edges. I would guess the rougher the
surfaces are, the sooner the laminar airflow separates
and the sooner the reed starts vibrating. If the reed
cannot start vibrating in time, it will "choke".
Probably it would be worth trying to enroughen the
surfaces and see what happens. My impression was that
Suzuki reeds probably have a smoother surface finish.
Whether I am correct or not and if this slight
difference is enough to result in the "locking up" of
the reeds, I don't know.
