To: harp-l@xxxxxxxxxx
I've been trying to gap for overblows and am finally
having some success. Even for harp that I don't
overblow, changing the gap has made a huge difference.
However, I almost always narrow the gap.
With this being said, I noticed that on my C and D
harps the 3 draw bends are very hard to bend in
comparison to lower keys (and similar keys of
different harps). In fact, I tend to choke them on
any keys higher then D way too much. I feel like
there is just too much of a change in technique from
key to key...especially when compared to bent notes
else where on the harp.
If I widen the gap, will the bend be easier to play?
What about with blow bends (not overblows)? If I
adjust those reeds, can I make them easier to play?
Or is just the nature of beast in terms of changing
keys?

High end harps play differently to low end harps, but with gapping you
can
reduce the difference some what.
Something that is helpful to bear in mind when gapping unvaluved diatonic
harmonica - Gap the higher pitch reed more than the lower pitch reed in
the
same chamber. The higher pitch reed can produce bent notes, and
therefore
doesn't choke as readily as its partner.
Eg. Key of D harmonica blow reed hole 4 is D5, draw hole 4 is E5. So
you
can increase blow hole 4 reed a bit more to reduce the chances of
choking,
while reducing the gapping of draw reed hole 4 to improve reed response.
Although if the difference in gapping between the two reeds is too wide
you'll run into trouble like having the reeds decouple while playing a
bent
note. And no matter how widely you gap blow reed hole 4, there is a
limit
to how close you can gap draw reed hole 4 before it chokes. But its good
to know you can get a bit tighter by compensating with the other reed's
gap.
Although if you are gapping a harmonica for overblows, there are other
considerations.
