In practice
- For how a bow feels, the balance point matters more than absolute weight. The closer it sits to the tip, the more head-heavy the bow feels.
- Too soft and the stick bottoms out under pressure, making spiccato difficult; too stiff and the stick responds less to your bowing.
- The ferrule at the frog holds and spreads the hair; it is a structural part, not decoration. Through the mass of the metal parts the bow maker also sets the balance point.
- The mother-of-pearl eye in the middle of the frog, by contrast, is purely a matter of finish.
- Slacken after every session so the stick keeps its shape. Never overtighten, apply rosin sparingly and wipe the stick.
- Sideways warp, lost camber or hair falling out unevenly are reasons to have the bow looked at in the workshop.

Sound and physics
The horsehair carries the string along in an alternation of sticking and slipping and produces at the bridge a sawtooth motion rich in partials, from which the body of the violin makes its own selection.
A 4/4 violin bow measures around 740 mm without the button (the screw head at the frog) and carries around 150 horsehairs, or 160 where the hair is finer. In a pernambuco bow, typically around 40 g of the total weight is the wood of the stick alone. The balance point of a violin bow sits around 19 cm from the lower end; the ebony and mounts of the frog keep it close to the hand through their material and mass.
The hair ribbon is 8 to 9 mm wide and gives around 65 cm of playing length. Half the hairs are set in the opposite direction, so the ribbon grips equally on up-bow and down-bow.
Massaranduba is a wood species of its own. It is considerably heavier than pernambuco.
On every Massaranduba model, as on the pernambuco bows, the frog is ebony. Every Götz bow is haired with natural white horsehair.
The Massaranduba models 62 with a round stick and 63 with an octagonal stick sit between 22 and 66 in this series. Up to model 73 the mounts and wire winding are nickel silver (an alloy of copper, nickel and zinc); from model 74 they are sterling silver 925. A lined slide means that the mother-of-pearl slide on the underside of the frog is framed in metal; the Parisian eye is a mother-of-pearl inlay in the frog, set in a brass ring. The frog is made of East Indian ebony (Diospyros ebenum); neither this ebony nor the mother-of-pearl on our bows appears on the species protection lists.
The stars on the stick show the quality grade of a pernambuco bow; besides the wood, details of the finish such as winding and button feed into this grading. Pernambuco bows are stamped on the frog and on the stick, Massaranduba bows on the frog only, and since 2025 every bow has also carried a laser-engraved serial number.
Our experience
Our experience from many consultations: as a guide to matching quality grades we recommend model 20 for violins of grade 98, model 66 for 107 to 110, models 70 and 72 for 112 to 115 and model 73 for violins from 120 upwards. We make bows to a requested weight or balance point only in pernambuco, from model 66 upwards.
Our Massaranduba is seasoned for at least ten years before it becomes a bow. We recommend Massaranduba bows for beginners because they bring the craftsmanship and fittings of our range at excellent value.
In our experience a model with a higher number brings a harder stick and more handwork.
Frequently asked questions
How much does a Götz violin bow weigh?
Our 4/4 violin bows weigh around 58 to 62 g. We do not offer very light bows of 48 to 52 g, because such a weight calls for a special build and leaves the pernambuco stick unstable.
What is the difference between models 72 and 73?
The fittings are the same; model 73 additionally has a titanium screw with a copper nut. At 4,510 kg/m³ titanium weighs little more than half as much as steel at 7,800 to 8,000 kg/m³.
What does model 78 S have that the 78 does not?
A silver tip plate at the head; otherwise the fittings are the same.
