What is rosin?

Rosin is typically manufactured from pine sap or tree resin. It is extracted directly from live trees via a tapping procedure, much like maple syrup (the process in no way harms the tree).

Rosin is purified before it becomes the amber-colored, sticky material we know and love. Rosin, when added to the horse hairs of a violin bow, aids in the creation of friction between the bow and the strings. Without rosin, a bow cannot hold the violin strings and make music.

Rosin is required for every musician who performs on a fretted string instrument such as the violin or cello. It is also a must for any electronic violin or viola. Without rosin, the hair of the bow will glide over the strings, creating insufficient friction to make music. 

The violinist must brush the rosin along the whole length of the bow to enable the bow hairs to develop hold on the violin strings and therefore make a sound. Rosin is required to play the violin, viola, or any fretted string instrument.

Even if you have the best bow rosin, you still need to apply rosin. Here’s how you put rosin on your bow:

Scratch your rosin block to bring the rosin powder to the surface.

Scratch the surface of the rosin with the screw of the bow or a nail file.

Start placing rosin on the bow hair using your tightened bow

This should be done in a motion akin to washing a counter stain or sparkling your shoes. Spend a few seconds in each part of the bow and evenly apply rosin throughout, traveling up and down the bow to get a lovely even layer. Again, don’t be hesitant to dig your bow into the rosin because you want the rosin to adhere to the bow hairs.

Test the amount of rosin on the bow

Test the amount of rosin on the bow by delicately taking the back of your finger and checking it like you did previously, but don’t do it too often.

If it’s a fresh bow, you may not detect much rosin in specific areas. If you’re being overly gentle with it, rosining a fresh bow may take up to five minutes.

Reapply

Once you’ve applied enough rosin to the bow, you must reapply it every 60 minutes of practice.

This is usually once every other practice session. Each time you apply extra rosin to the bow, it generally only takes five to ten seconds to be effective.

Advice for new bows:

• Aim for a consistent application throughout the length of the bow.

• Apply the rosin on the new bow in a brief back and forth motion to ensure a consistent quantity of rosin is applied.

• For a fresh bow, 10-15 seconds should be enough to apply the appropriate quantity of rosin.

• Don’t be concerned if you apply too much rosin; it will fade off as you play. Rosin dust should be gently cleaned up using a craft cloth.

Tips for adding rosin to a bow that has previously been rosined:

• Long strokes should be used throughout the whole length of the bow.

• A good rule of thumb is to apply 10 even strokes to your bow for every hour of practice.

• Other options include rosining your bow once a week or a little bit each time you play. Depending on how much you play your instrument, determining the perfect quantity will take some time!

How much rosin is required?

Experiment with how much or how little you apply over time to see how varying quantities alter your playing’s feel and sound.

There is no rosin.

You’ll note that no rosin, or very little rosin, produces a hollow and pallid tone – and that you’ll have to push considerably harder to produce any sound at all.

There isn’t enough rosin.

More rosin, but not quite enough, will produce more sound, but it will be inconsistent because the bow will struggle to move smoothly, yet with sufficient friction, over the strings.

Rosin that is just just

When there is just enough rosin (four to five strokes), the bow travels effortlessly and consistently over the strings, producing warm, rich tones.

There is too much rosin.

You’ll know you’ve used too much rosin when, in addition to the cloud of rosin that emanates from the bow as it goes over the strings, the bow feels “stickier,” needing more effort to move, and the sounds are scratchy and harsh.

Rosin application will become an automatic part of your technique before you realize it. Until then, keep these pointers in mind to improve your rosining skill.

FAQs

How often should I rosin my bow?

In general, we find that players reapply rosin every 4-6 hours of solid play. Professionals normally do this once a day, but for novices playing 15-30 minutes each day, we found that once a week is sufficient.

Should I clean the rosin off the strings?

Rosin dust, which builds on the face of a violin every time it is played and may harm the varnish if not wiped away after each playing session, is the most hazardous kind of filth. Rosin dust should constantly be swept away from the strings and fingerboard. It is advisable to use a soft cloth for this reason.

Do you wipe the rosin off the bow?

Fortunately, the cure is sometimes as simple as wiping the rosin accumulation on the bow with a soft cloth. If the rosin accumulation is too persistent, a warm, moist cloth dampened with wood-safe detergent can assist the sticky mixture loosen and come away with the cloth.
