7 limit tuning
Hi Kinya
i have a question about the 7 limit tuning and that "pre-war sound". I am interested in changing the temperament of a harp that is a modern compromise tuning to a 7 limit / pre-war type tuning
I really love the sound and I'd like to try it out. I undstand tunings have changed a lot over the years and I am not up on all the details. But it seems 19 limit, compromised and Equal temperament covers a lot of the territory In the current landscape.
You do talk about this in your videos but my question is really about taking a modern harp that is in say a compromised tuning (I mostly play Seydel 1847's) to 7 limit tuning which is what I think was common in those pre-war days. The goal is to get that nice chordal sound you hear. I understand there are limitations (pun intended) but wanted to hear you thought on this approach. And if it is a major thing or something that would be a walk in the park for a harpsmith!
Best,
Andrew
Hi Andrew
Yes. That is sage advise. ALWAYS PRACTICE ON A THROW AWAY HARMONICA.
This is especially true when learning to tune "down" (flatten) the pitch of a reed. The reason being, tuning down requires removal of metal from the rivet side of the reed--to slow it down. This "back end" of the reed is where the flexion occurs. If too thin, the reed will fracture prematurely (probably during a gig ;o(
In addition to flattening the 5 and 9 draw reeds, you will also need to flatten the 2+blow, 3draw, 5+blow and 7draw.

I tune lots-0-reeds down a lot further, with no problems. When done properly it can extend reed life rather than shorten it. If you dig it out in one spot it can lead to a stress point.
Thank you Joe
For first "timers", can you elaborate on the best techniques for them to learn.
Much appreciated, Kinya
For stainless steel reeds I use Shofu Brownies chucked in a varible speed cordless micro motor that's used in the nail salons. It takes metal off by polishing. It goes fairly fast. You can also use them on brass reeds. I've found a sanding wand works well too. Both tools don't gouge the reeds.
I use the Sleigh scraper, 220# sandpaper folded up works fine too.
The Sleigh scraper is a fantatic tool for brass reeds. Do not use it on stainless steel reeds.
Sorry I overlooked that the OP was about stainless. I break out the power tool for those:)
Thank you Sensei Jon and Sensei Joe!

Andrew,
I'm not familiar with the numbers. I use the bullet shaped brownie. As I tune the reed the brownie will clog so I keep a piece of 220 grit sandpaper to quickly dress it. I buy my brownies either on eBay or at Otto Frei, a jewelry tool dealer in Oakland, CA. They have a website. I buy them by the dozen.
For the micro motor I use the WeCheer WE 243. You can buy them on Amazon but I've been able to find them online for less at stores that supply the nail salons. Sorry, but I can't remember the name of the company ( the site had a lot of pink and lavender colors ).
I would email Richard and look on Rockin' Ron's if he has any Sleigh tools.
I haven't used sanding wands in quite some time. They work. I got mine from Micro Mark online. They have a pack os 4 with different grits. I'd start there.
Thank you Jon!
Here is the link for the MicroMark sanding wands:

Hi. is there a table with how much cents up or down must be in wich hola up and down to get that kind of tuning? For example hole 1 blow 0+3 cents, 1 draw 0-2 cents. Etc. or something like that. Thanks alot :)
I sent you the recipe in another post for "Compromised Tuning"

Thank you, good day
Hi Andrew. It's good to hear from you.
This "just intonation" project will be fun for you---if you have prior tuning experience.
So, before I lay out the process, are you comfortable with tuning harmonicas (Seydel)?
