The influence of different material tailpieces and chinrests on violin Sound

In my experience, trying different chinrests was very interesting.  A luthier saw my center-mounted chinrest, and he suggested a side-mounted, taller profile chinrest with titanium hardware.  The chinrest switch was like taking a mute off.  It was weird, and the effect wasn't just under my chin but clearly audible to folks in the room.

MJ Kwan has presented some really valuable stuff in the past, so I would look forward to that.

The placement though, is probably what caused that. My chinrest is the SAS thing that many of us with taller necks need, and simply moving that around has massive changes in the sound. I was taking an audition, the violin was sounding great, and the chinrest fell off... Hadn't been tightened down enough (or maybe I was tense and gripping everything too tightly). I put it back on, probably 8mm away from where it was, to try. It felt much better, the violin sounded dead. I finished the audition like that, and days later moved it back. The violin sounded really good again.

If I had to bet, I'd say the glue right under the chinrest was failing, and the chinrest was/is holding it together. Alas, I only get to visit a shop every year or 2, so it will be that much time before I can get open seams glued. All that to say, it's impossible to say if your new chinrest made a difference because of the material, or where it clamped down on the violin.

Valuable insights. Chinrest positioning can make large differences in sound and response, even when no open seams are involeved.

Not that I expect you to share the secrets to your bread and butter, but have you observed any trends in placement?

For me, it seems that the closer to center, the worse the sound and response, though that's really where I think I want it. I'm sure there are tons of variables, but just curious about general trends.

I usually find that side-mount chinrests work best for what I want.

Center-mount chinrests usually have a large cantilevered part, and its vibration can get into the playing range and cause some disturbance.  However, if you keep your chin clamped on it, that should eliminate the effect.  I don't "clamp" with my chin (being a fiddler), so that might be part of my preference for sidemount rests.

Cool.  I was wondering when someone would get around to commercially squishing out all the air from wood for the musical instrument field.  I think they should have a dyed product to look like ebony, though.

I don't see any price list (probably 'cuz it's expensive)... anyone know?

Quite often a middle mounted chinrest "kills" B1-, both in amplitude and frequency, sometimes lowered by ~20 hz. Sometimes B1- is not even a clear peak when mic is on the front side and a normal tap to the bridge. It doesn't help much on such violin to change to another middle mounted one. The only option is to change to a side mounted, to get the violin to live up

When referring to "middle mounted", are we talking specifically about ones that the cup of.the chinrest is directly over the tailpiece, or just that the rest is seated and clamped on either side of the tailpiece on the sides of the end block, regardless of whether the cup is above or off to the bass side? Or center as opposed to one that is totally mounted to the left.of the tailpice?

Yes, it's expensive. Comparable to the corene boards - also Swiss. Makes you wonder what's in the water there.

The motors on the first 3 Mars rovers were also from Switzerland.  I visited the factory a couple of times... gorgeous place at the side of a lake, surrounded by open fields with grazing cows.  And they were building an expensive multi-story parking structure on a small patch of land, as there were barriers to just purchasing and paving over a pasture.  A different set of priorities for sure, but I can't argue against the result.

I'd imagine that when someone talks about a center mount chinrest, mostly they are talking about the kind that clamps on both sides of the tailpiece. I'd imagine that tends to be a problem because you're restricting the flexibility of the plates much more than if just 1 spot is clamped down. Not that I know anything, but that's got to be why side mounted is better. You're not restricting the movement of the plates quite as much, and you're clamping on the side of the bassbar, which tends to not move as much anyways.

I think this is the main reason for the success of this type of chinrest, a solid point where clamp pressure does not involve too many risks, even if inadequately strong.  Too many violins has wavy or cracked ribs due to the pressure of the side mount chinrest, especially if inappropriately tight clamped for long time. I think that a reinforcement inside the rib would be essential to avoid as much as possible the problem from inappropriate clamping force from these kind of chinrest.

My thought too, which is why I reinforce the rib on the bass side of the lower block.717957015_sidemountreinforcement.jpg.6a886fb79805140db618d6b70fc4164a.jpg

B) Out of curiosity, do you round off the linings and then adapt the reinforcements or are the reinforcements continuous and in contact with the rib along the entire height and the linings interrupted?

I'm beginning to believe the entire rib perimeter should have many of your reinforcements to stiffen the rib assembly.  This will create more of a "clamped" edge effect rather than a "hinged"  edge for the plates which will raise the B1- and B1+ mode frequencies.  These frequencies can be lowered back towards their original frequencies by thinning the top and back plates.  The plates' lowered mass and stiffness should increase the violin's sound output.
