Becoming a great musician requires getting to know every part of your instrument, including accessories like rosin. While you’ve been told you need to rosin your bow regularly, do you know what rosin actually is and the role it plays?
Learn more about rosin, including where it comes from, how it works, tips for applying it, and more.
What Is Violin Rosin Made Of?
Violin rosin comes from resin. Similar to sap, resin is a gooey material that comes from pine and conifer trees. Once the resin is collected from a tree, it’s heated, purified, and poured into molds to solidify into rosin. Depending on the manufacturer, other ingredients may be added to the rosin, like beeswax.
The rosin you order online or pick up from your local music store usually comes in a round cake or rectangular block that you can rub against your bow hair.
What Does Rosin Do for a Bow?
Violins rely on the friction between the bow hair and the strings to create the string vibrations that produce sound. Bow hair on its own is too smooth to grip the strings, leading to a lack of vibration. If you try playing with a brand new bow or “naked” bow hairs, the sound will be barely audible.
You need to apply rosin to the strings to create the friction necessary to vibrate the strings and produce notes. When you apply rosin, you coat the bow hair in a powdery, sticky substance that allows the hair to grip the strings as it slides across.
Rosin’s uses can go beyond string instrument bows. For example, some fiddle players apply it to the bridge to help prevent movement. In a powdered form, rosin is even used by athletes like ballet dancers, bowlers, and gymnasts to improve grip and prevent slipping.
Selecting a Rosin
You have countless choices when it comes to picking your rosin. There are different brands, shapes, and darknesses to consider. Boxed rosin is usually cheaper and preferred for beginners, while caked rosin leans more expensive but is better for professional use.
As for color, lighter rosin is harder and helps produce a softer sound, making it the better choice for violinists and violists. It’s also great for warm, humid climates. Darker rosin is softer and stickier, making it the preferred choice for cellists and bassists. Unlike light rosin, dark rosin fares better in cool, dry environments.
As you advance in your skillset and explore different bows, techniques, and instruments, you also want to experiment with your rosin. Don’t be afraid to test out different brands and types until you find one that produces the sound you like. Be sure you clean the hair in between each rosin, though.
Tips for Applying Rosin
Rosin application isn’t an exact science, but you want to avoid applying too much or too little. Not enough rosin, and your bow will slip against the strings and produce too quiet of a tone. Too much rosin and you could wind up with a harsh sound.
You also want to ensure you are applying rosin often enough without overapplying. Below are some general rules of thumb to follow.
- Score new rosin before using
- Don’t touch the hair with your fingers
- Apply more rosin to a new bow than a used bow
- Apply rosin in even coats
- Use about 4 to 5 strokes of rosin each application
- Reapply rosin after about 4 to 6 solid hours of playing
- Gently clean the hairs with a cloth to remove excess rosin or residue buildup
