How to Rosin a Bow
A bow without rosin will produce virtually no sound when it’s drawn across the strings of an instrument. But when rosin is added to your bow, it’s able to “catch” the strings and produce vibrations, which result in the music you hear. If you’re starting with new rosin, you’ll need to rough up the surface. Then you can make your first application to a new bow or regularly apply it to an old one.
Method 1 Choosing and Preparing the Rosin
1. Buy light rosin for smaller instruments. There are different types of rosin, but the two most common are light rosin and dark rosin. Light rosin is harder, and not quite so sticky as dark rosin. It's sometimes called amber or summer rosin (for the time of year it's tapped), and it's appropriate for the higher strings, like violins and violas.
2. Choose dark rosin for a fuller sound for larger instruments. Dark rosins, or winter rosins, tend to be very sticky. The stickier the rosin is, the fuller the sound will be. Select a dark rosin if you play a low-stringed, large instrument like the cello, for which a fuller sound is preferred.
3. Select boxed rosin for a durable, low-priced option. Boxed rosin, as its name suggests, comes in a box, which makes it less prone to cracking and breaking. It's typically only available as a light or summer rosin and is usually a lower quality than cake rosin. But its low price tag makes it a good option for beginners.
4. Opt for cake rosin for a higher-quality product. While cake rosin tends to be more expensive than boxed rosin, you're getting a purer, more high-quality rosin. It comes in a variety of colors, from amber to black, so you can select the best kind for your instrument.
5. Rub new rosin with fine-grit sandpaper to increase stickiness. New rosin needs to be roughened in order for it to stick to your bow. Take a piece of sandpaper, around 220-grit, and rub it all over the top of the rosin block. Stop when you see the rosin producing dust.
You can also use a knife to score it and cut a crosshatch pattern into the top.
Method2 Applying Rosin to a New Bow
1. Tighten the bow. Twist the screw at the end of the bow and tighten it until it appears straight and parallel with the hairs. Then slacken it just a little until you see the curve reappear in the wood. This is the best position for the bow to be in while you play.
Don't touch the hairs or bounce them on your arm, as this will make them greasy and harder to play.
2. Hold the rosin in your left hand and the bow in your right hand. It doesn't matter if you are right- or left-handed, as you always hold the bow in your right hand while playing. Cup the rosin block in your left hand, being sure to keep your fingers off the side you’ll be stroking the bow against.
3. Stroke the bo
