Anyone working with soundports on violins?

Post by Anders Eliasson »

Thats the question: Anyone working with soundports on violins?
If so, how does it affect the sound of the violin?
I´ve made many flamenco guitars with soundports and I like ported flamenco guitars a lot. But its another very different instrument. The Spanish guitar is not specially loud and the soundhole bursts sound away from you. With a port you get more volume for yourself and a nice stereo or surround sound like effect.

Doesn't the violin already blast the sound to the player's ear?
I may be crazy...but I'm not insane.

The Catgut Acoustical Society has experimented with that concept many years ago. One violin they used had holes all along the ribs and they would plug them in various configurations with corks to change the resonant frequency of the air chamber. Check their web site for more information.

Oops, other than ff holes as soundports. I don't know what to say.
If you meant soundposts, then I can answer this



Anders,

I must say that this post, if asking about soundposts, to a violin maker, has really only one *standard, correct* answer.

As you look at the violin, head on, as if the front were a standard map, the post goes inside the belly just below (south of) the treble foot of the bridge's leg - I say about the thickness of the belly below the line of the bridge foots south edge. Perhaps more, perhaps less, and perhaps just a tad east or west of that position, may be correct for the tone of that particular fiddle. But starting off making any post you,ll be lucky to get it the right height and the ends trimmed correctly to contact the inside top and bottom plates perfectly evenly anyway, where it belongs. Which they should do.

The post should just fit in with enough pressure so that, without strings, it will just fit tight enough to stand on its own.

Some makers put the post it's own diameter below the right foot of the bridge - some tighten it up a bit more.

A lot depends on the violin. And the maker.

Once you are able to correctly fit a bridge on either of these positions, vertically and with the ends correctly trimmed, you will have already learned most of the other things having to do with setting a violin sound post.. So until you can roughly fit the post "standardly" most of the finess about fitting it, doesn't really matter much and will be beyond caring much about.

It's a pretty standard job. So correctly fitting one should be pretty achievable - given a certain amount of practice, time, and attention to detail.
