Sound and physics
The fitting is a closed U-bracket made of commercially pure titanium Grade 2 to ASTM B348, without aluminium or vanadium content. For the same shape, the fitting therefore weighs just over half as much as one in brass.
The lower bridge that rests against the back is deliberately curved by 1 mm; this directs the main force precisely into the area above the bottom block, where the wooden block inside reinforces the body. Instead of one through hole, the two barrels have three blind holes for the adjusting tool, which therefore cannot protrude beyond the barrel or touch the rib. The blind holes also allow a longer internal thread and so more adjustment range in a compact build.
- Violin 4/4 and 3/4: 8.5 g with cork, barrels 22 mm, span 40 to 55 mm
- Viola: 9.6 g with cork, barrels 29 mm, span 46 to 60 mm
- Span measured from the height of the drill hole in the chin rest wood to the lower edge of rib and back
Our experience
Our design idea: when the force is introduced above the bottom block, the freely vibrating area of the back stays free of clamping pressure, and we hear a freer, more open sound in this than with a straight lower bridge. We have been making chin rest screws in our own house for around 120 years, and three years of development have gone into this fitting. We oil the thread with our own modified, thickened linseed oil; after a long rest it turns a little stiffly at first, by design, and then runs silky smooth.
Frequently asked questions
Will the fitting suit my existing chin rest?
The Götz thread is a standard that has been widely adopted over many decades; the fitting therefore suits older Götz chin rests and many chin rests from other makers.
Does the fitting contain nickel?
No, it is made of pure titanium with no alloying elements and no coating.
Does the thread need oiling?
Yes, pure titanium runs a little stiffer than alloys and should be lightly oiled.
