Playing the violin to its fullest potential requires a quality bow. Get the best sound by understanding the bow’s materials and its various components.
What are the Different Parts of the Violin Bow?
The bow has different parts. As a beginner playing the violin, you should know these parts of the violin bow:
Key Takeaways
- The Stick: Typically made of Pernambuco or Brazilwood, the stick is essential for balance and flexibility. Modern sticks may also use carbon fiber for durability and affordability.
- The Hair: Usually made from the tail of a white Mongolian Stallion, the hair is crucial for sound production. Black hair is also used but primarily for cello and bass bows.
- Bow Screws: Located at the end of the stick, bow screws allow players to adjust the tension of the horsehair, which is necessary for proper sound production.
- The Frog: Made from ebony hardwood, the frog secures the hair and includes decorative elements like a silver “eye” or abalone shell.
- Materials: Pernambuco wood remains the best choice for bow sticks, though it’s getting scarce. Alternatives include Brazilwood and modern materials like carbon fiber and fiberglass.
1) The Stick
The stick is the most prominent part of the bow. As the backbone, it supports the bow and handles pressure during violin playing to produce great sound. Made of hardy and resilient Pernambuco wood or the less expensive Brazilwood, these materials primarily come from Brazil. Brazilwood is less dense and less responsive than Pernambuco.
Besides these two types of wood, modern materials are used for sticks, created using contemporary technology. Fiberglass and carbon-fiber sticks are gaining popularity. Fiberglass is perfect for students seeking an affordable bow, while carbon-fiber bows are popular and suitable for any violin player.
2) The Hair
The violin bow has hair that touches the violin strings to create sound. Modern bow hairs are cut to the needed length by heating them with an open flame. The hair, coated with rosin, grips the strings when slid and pulled along them.
The bow hair is usually made from the tail of a white Mongolian Stallion, which provides the best quality. Some bows use black hair, which is coarse and not ideal for violins but suitable for heavy cello and bass players.
The hairs are positioned at the top and bottom of the bow, secured with small wooden wedges. These wedges create tension to hold the hair in place.
3) The Bow Screws
The main mechanical part in a violin bow is the bow screw. This small screw is located at the stick’s end and lets the violinist twist it to adjust the horsehair tension. Tightening the hair is necessary to play the violin. Adjusting this screw not only fine-tunes the bow’s grip but also prevents the stick from warping due to excess tension.
4) The Frog
Made of Ebony hardwood, the frog has an unusual appearance among the different violin bow parts. Located near the grip at the bow’s bottom, it keeps the hair in place. One side is U-shaped, and the other is square-shaped. The frog sits on the stick and is secured with wooden wedges and a metal ferrule system. Often, it features a silver circle, called the “eye,” and sometimes an abalone shell decorates it.
Different Types of Materials & Woods Used to Violin Bows
The bow is mainly a long wood piece with materials between its ends. Hair fibers typically run along the wood’s edges, while some cultures use a single string instead. Violinists should consider the bow stick’s material, choosing between Pernambuco, Brazilwood, and carbon fiber.
1) Pernambuco Wood
The main wood for a violin bow’s stick is Pernambuco, used since the late 18th century. It’s dense, heavy, and native to Brazil. This wood balances elasticity, strength, and responsiveness. Pernambuco has many subspecies, offering various options.
If you’re a master bowmaker, you’ll spend extra time finding the best Pernambuco sticks. You’ll reject many woods to find those with the right elasticity, responsiveness, and strength. However, Pernambuco is scarce due to forest degradation. Also, Brazil restricts its cutting and export. Now, finding a Pernambuco violin bow is very difficult.
When you examine the quality of Pernambuco used for bows, you’ll see a decline over time. Earlier bows made from Pernambuco were of excellent quality, but recent ones aren’t as good. Experts think the Pernambuco species used in the past became extinct by the early 20th century.
2) The Brazilwood
The Brazilwood covers different types of tropical hardwoods. It’s a great alternative to Pernambuco, being more affordable and perfect for beginners and intermediate violin players. Brazilwood violin bows range from $50 to $200.
Modern technology has expanded the materials for bow sticks, including fiberglass and carbon fiber. These materials make bows more affordable for students and beginners. Some bows use cheaper woods, which are less expensive but lack good quality.
2) Carbon Fiber
Carbon Fiber is a remarkable material created using modern technology. These fibers, around five to ten micrometers thick, consist mostly of carbon atoms. They offer high stiffness, low weight, impressive tensile strength, strong chemical resistance, and high-temperature tolerance, with minimal thermal expansion. Often combined with other materials to form composites, carbon fiber makes a great base for violin sticks. Synthetic bows made from carbon fibers are available for both beginners and intermediate violinists.
The Contemporary Violin Bows
I owe the creation of the modern violin bow to 19th-century bow-maker Francois Tourte. He discovered that Pernambuco wood was perfect for violin bows because of its resiliency, weight, beauty, and strength. Since then, Pernambuco became the standard material for violin bows.
The making of the bow requires perfection. Bow-makers shape the curve (cambre) of the stick by carving and gradually heating it. The screw in a contemporary violin lets the frog move and adjust the hair’s tension, which typically consists of up to 150 hairs for effectiveness.
Cheaper bows often use synthetic or nylon hair. Applying Rosin, a sticky tree sap substance, creates more vibration on the string, producing better tones.
