What I know about Randy's cutting reeds for a Bb accordion

What I know about Randy's theory is that he thinks shorter reeds respond faster and have a brighter timbre.

He explained to me about how he has done some Bb accordions so that they aren't "lazy" or "dull." Instead of using a set of Bb reeds, be basically uses a set of C reeds (which naturally would be shorter than a set of Bb reeds) and retunes them to match the C pattern. In order to do this he has to mount the reeds in different position.

For example, you can't just mount a number 5 in C (which would be G on push and A on the Pull) on number 5 on the Bb. You have to use the reeds you would normally use on the 4 of a C (which would be E on push and F on the pull) on the number 5 button of the Bb accordion. Then you must retune the reed so that the number 5 button plays F on the push and G on the pull--this is the proper pitch for the #5 button on a Bb.

In order to make these last tuning adjustments, (which require raising the pitch of the reed or making it "sharper in pitch) he may be "clipping a bit of the reed tip (this part is a guess, by the way)...otherwise you would have to file a lot off the tip end to bring the pitch up. This might be what he means by "cutting the reeds."

I am not positive about the cutting...but I know that is what he calls this practice of making a Bb accordion from a set of C reeds.

Anyway, the claim is that this Bb accordion with a set of reeds with shorter reed tongues made from a C is supposed to have more of the bright timbre of the C even though it is pitched a whole step lower than a C...in effect...it is a Bb accordion with the tone color of a C.

Re: What I know about Randy's cutting reeds for a Bb accordion

Chris is correct, in a since, you just bring down all of the reeds one row, then put a regular set of Bb's at the number 10 row. In my new quest to build accordions my plan is to make all of the Bb's this way. Takes a bit more time to do but it is still very loud and powerful, as Chris says the "timbre" is like that of a C. Thanks Chris, new word for the day !

Re: Re: What I know about Randy's cutting reeds for a Bb accordion

completely clear, Rusty and Chris.

Funny thing is that I think that the C reeds of a Castagnari one row (Antonelli a mano reeds) I posessed were shorter than the Binci's. (so simular story as your Bb) But I have to measure.
Which is sure that the antonelli's had a direct (fast, loud) tone, but with a short time duration/ no echo when stopped; dry sound. But this is non scientific subjective...
Somebody called it an 'old sound' referring to the older instruments (John Delafosse maybe; while they had big reeds, I heard).
One thing was extraordinary. I never had to retune them for more that 8 years. Reeds looked very sturdy too. (they are now in an Eric Martin cajun accordion, and this proves that the construction also makes a cajun sound, the castagnari wasn't really cajun, the martin 100%)

MLMH

To anyone else with Martin boxes.... is yours set up MLMH too?

I wonder if he had to set it up like this because I had its switched from Binci to Salpa.

It is really bizarre but the first set of mid reeds are definately longer than the lows.

What is done about button number one?

Re: Re: Re: What I know about Randy's cutting reeds for a Bb accordion

You would put a regular set of Bb reeds on the number one row. Since this row is such a low and "bassy" tone, a difference in sound can barely be heard.

Re: Re: Re: Salpa sizes and other stuff

If anyone says they can tell you the brand of an accordion by just listening to it and not seeing it. They are dealing in falshoods.

Re: Re: Re: Re: Salpa sizes and other stuff

I do know that hand made accordions are never 100% alike. I do know that certain builders have certain ways of tuning the reeds. I'm not talking about wet/dry.

People may say that Salpas sound brighter than Bincis. I think it all depends on how the maker tunes the reeds. I've got 2 accordions with Bincis of the same brand.

They sound way brighter than a different brand that has Salpas. In fact one of the reasons I wanted to have the Bincis out of this accordion is because I didn't recognize the sound I'm used to.

The brands of accordions I mentioned, I have played extensively enough to know what they sound like. I couldn't name them by means of a recording, but I know the style of tuning.

From listening to thousands of hours of playing my different brand Cajun accordions, this is not true at all.

Descriptive words on sound

I don't even know if brighter is the right word... Maybe crystal clear, maybe even thinner in someone elses opinion.

Maybe thinner is the word. I don't know enough about tuning reeds to presume, but my favorite builder has written about tuning reeds, but never ever specified how he does it "by ear" to me.

Perhaps the reeds in my favoritve accordions have been scraped "thin" enough to sound brighter?

I don't know how it's done, but I know I've heard Bincis sound different in different brands. In fact, VERY different.
