Chinrest Viola, Schulze-P, Ebony, Titanium, ZK-V252-T
ZK-V252-T
A lighter, slimmed-down form of the Guarneri: mounted centrally over the tailpiece, with a small wing to the left; the plate extends a little to the left. Black stained ebony with the white Götz mark, the heaviest of the three woods.
- For players who like the Guarneri construction but want less wood at the chin
- Screws and barrels in pure titanium, uncoated and free of nickel
- Sized for viola rib heights
Technical data
| Model | Schulze-Priska |
| Material | Ebony |
| Fittings | Screws and barrels in pure titanium |
| Instrument | Viola |
| Item number | ZK-V252-T |
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.
Guarneri, Stradivari and Schulze-Priska are mounted over the tailpiece. Together with the Varga, these shapes differ mainly in how deeply the dip is curved: of the four, the Stradivari has the deepest and most contoured plate, the Varga follows, the Guarneri is gently curved and the Schulze-Priska has no curvature. The deeper plate guides the chin more closely and so gives more control.
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 the viola we like to recommend the Varga instead of the Guarneri.
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 to rest the chin beside the tailpiece will find a flat, side-mounted shape in the Kaufmann or the Slim Style.
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.
Which of these chin rests has the deepest dip?
The Stradivari, followed by the Varga; the Guarneri is more gently curved, and the Schulze-Priska has no curvature.
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.
