Re: [Harp-L] eed tuning questions

["Ben Bouman" <fitgo@xxxxxxxxxx>]

A few days I made a mistake on a Bb beta-harp ( = seydel 1847 with steel 
reeds)...
I tuned 1 blow up 2 semitones....but it had to be 3 semitones down....  so I 
tuned it down and it worked well with the steel reeds...
So that's tuning down a reed 5 semitones!!
For tuning I use a Dremel at medium speed and blue Shofus... it is more like 
polishing at high speed and it takes away very little material. It took me 
some time to get used to the feel but now I can tune up or down by a few 
cents in a controlled way.

In my experience a reed can be tuned down 3 semitones by removing material 
from the base without weakening the reed - I have reeds that have lasted for 
several years after having been returned this way. I use a sanding wand and 
remove metal gently from an area about a quarter of the length of the reed 
starting from the base.

I've never noticed any dullness from reeds tuned down either with material 
removal or solder.

Doug asks:

"1. How far up or down can I expect to easily tune a reed before I wreck
it?"

Others will disagree with me probably but I say 2 semitones, or a full step.
Beyond that you are probably going to damage the reed unless you are
EXTREMELY careful and you use a consistent method that's easily repatable.

2. "I've heard that solder can be used to lower the pitch - is that required
to
get just 4 semitones?"

Yes adding solder to weigh down the reed and then tuning back up to the
pitch you want is the way to go; you can also remove material from near the
base of the reed (the dog) but you are weakening the reed a lot and it won't
last. But soldering is not as easy as it sounds and you have to be careful
about staying near the end of the reed and not letting it drip too far
toward the middle. And then there's the issue of cleaning up the sides
after adding solder - it's a pain in the first place but 4 semitones is 2
full steps - like from A down to F. That's a lot. I've tried it and it
worked but I was left with a very dull sounding reed. It plays but it's
much darker than the adjacent reeds.

You need to replace the reed with one of the proper pitch, which may have a
lot of solder, but done properly and cleaned up and pitched already.
Better, I think, to develop your reed replacement skills.

3. It would make sense for me to set up some kind of 'tuning station'. Best
not
to reinvent the wheel so any info or direction on this would be helpful."

I've never done this on a large scale so I got nothin' on this one. But
good luck. I hope you're able to accomplish what you want. Which is what,
by the way?
