Features
- Contact points lined with Portuguese cork
- Height means the distance between the top and the plate. It depends on neck length and shoulder rest: those who set the instrument high get by with a flat chin rest, those who carry it lower need more height
- Higher models are usually heavier. In our experience a heavier chin rest makes the sound a little warmer and darker; a light one leaves it more open
- The ebony we use is not subject to CITES requirements
Sound and physics
Viola barrels come in 32 mm and 35 mm; many viola models are supplied with one pair in each length. What counts for the choice is the rib height at the lower bout, measured from back to top.
Acoustically, the chin rest adds a mass with its own damping to the edge of the body through a few contact points. It therefore mainly slows those natural vibrations of the body that move strongly at these contact points, and leaves free those that have a node (a point at rest) there.
The viola chin rests we have weighed come to between around 55 g and 67 g including screws.
Ebony is the densest of the three woods we use for chin rests, followed by rosewood and boxwood. African ebony (Diospyros crassiflora) has a density of 1,000 to 1,050 kg/m³ at 12 % moisture content. Only the deep black heartwood is suitable for instrument making; the broad sapwood is discarded.
It is stained mainly with walnut stain and then polished; this gives the even black surface. After making, our chin rests are stored for several months so that they dry through completely.
Of our models, the Stüber is the one most strongly designed for chin support. The Hamburg has a higher curve at the top that gives the chin extra grip, and it runs out longer. Compared with the Hamburg, the Stüber is rounder and smaller.
We make the Hamburg in ebony only, the Stüber in ebony and boxwood. For the Hamburg we use deep black ebony of documented origin. The two viola Stübers ZK-V301 and ZK-V303 differ only in wood, not in size.
On the versions with the suffix -T, screws and barrels are made of pure titanium. Screws and barrels in titanium Grade 2 weigh around 42 to 44 per cent less than the same shapes in steel.
On the Guarneri in rosewood the scales show the difference: around 51 g with standard metal screws, around 45 g with titanium screws. Pure titanium contains no nickel and resists corrosion without any coating, including from perspiration. A thread in pure titanium runs a little stiffer than one in an alloy and therefore likes a light oiling.
We make our titanium screws ourselves in Wernitzgrün. We offer titanium in the closed design only; pure titanium cannot be brought into the geometry that Hill fittings need.
Our experience
When we advise on a viola, we ask for the rib height and then put together the matching pair of barrels. Our experience with tightening applies to the viola as well: only firmly enough that the chin rest holds securely, because the rib beside the bottom block is more delicate than the spot directly over the block.
For anyone who wants to play without a shoulder rest and hold the instrument securely with the chin, our first recommendation is the Stüber.
For us titanium is the choice when a chin rest is meant to stay on the instrument for decades: in normal use we know of no limit to its lifespan.
When another model suits you better
Anyone who prefers a flat, side-mounted rest will find it in the Slim Style or the Kaufmann.
Anyone who values the classic Hill fitting will find it on our models with gold-plated Hill screws, whose feet are firmly joined to the chin rest.
Frequently asked questions
Is the ebony coloured?
Yes, our ebony chin rests are stained and polished so that they are evenly black. Anyone who wants to see the natural figure of the wood chooses the unstained version with the suffix -NAT.
How dense is ebony compared with rosewood?
On average, African ebony at around 1,030 kg/m³ is just under a fifth denser than East Indian rosewood at around 870 kg/m³.
Do you also make the Hamburg in rosewood or boxwood?
No, we make the Hamburg in ebony only, stained or unstained.
Which of the two gives more hold?
For pure chin support the Stüber; with its higher curve at the top the Hamburg offers good grip for the chin.
Can I convert a chin rest to titanium later?
With models that have closed screws, yes; the titanium screws are also sold individually for this. Models with Hill screws cannot be converted to titanium.
