What is rosin? Why do instruments need rosin? How do you rosin a bow? Violinist Jamie Hutchinson has just finished a session at Abbey Road Studios, where she discusses:
- What rosin actually is
- What rosin is made of
- How rosin makes a difference
- The best way to apply rosin
Using her 300-year-old Italian violin to demonstrate, watch the film now, then head over to look at our Beginner’s Guide to the Violin.
What is rosin?
Rosin is a solid form of resin (the sticky substance that seeps out of trees; similar to sap). But while sap is used to make syrup and medicines, resin is used to make things like varnish and glazes.
How is rosin made?
Violin rosin is made by heating liquid resin until it becomes solid. It smells like pine and has a glassy, orange look. It’s also very brittle in texture, so if you drop it on a hard floor, it will shatter like glass.
Why do you need rosin?
Without rosin, there isn’t enough friction between the hair and the strings – so the sound of the instrument is barely audible. The bow just glides off the string. Applying the rosin creates the friction needed to allow the hair to grip the strings and make them vibrate more clearly.
Students Be Careful
HOW TO ROSIN YOUR BOW​
Every string instrument needs rosin. Here are the steps to successfully rosin your bow.
Time Needed: 1 minute
Total Cost: $ 5
Step 1
Make sure your bow is tight. Applying rosin on loose bow hairs can cause damage.
Step 2
Start with your rosin cake at the base of the bow. When applying rosin, do it slowly and gently. Pass the bow across the cake's surface from the bottom of the bow hairs to the top. Back and forth.
Step 3
Don't touch the hair with your finger (the grease on your fingers isn't great for the rosin to stick to the bow)
Step 4
Do just a couple of strokes; be careful not to apply too much rosin. Little and often is the key to success!
Step 5
Rotate the cake rosin, so the surface wears equally.
Step 6
As you play, you'll notice fresh rosin dust float onto the strings and instrument. Just use a soft cloth to wipe excess rosin dust off as and when necessary.
Bonus Tip:
To make light work of cleaning your instrument, we recommend the ToneGear Rosin Remover.
- It cleans all of your strings, all the way around
- It removes the excess rosin quickly and easily
- It keeps your fingerboard clean
- It makes the strings last longer
- You don’t need to carry chemicals around with you to clean
It really is a no-brainer!
How to rosin a brand new bow
Your new bow will come without rosin. So for the first time, you’ll need to do between 30 to 50 strokes to build up a base layer of rosin on the bow.
Take your time; go too fast, and it’ll heat up the rosin and cause it to melt. Expect to see a lot of dust; especially on the first time you rosin the bow. Don’t worry though; it’s totally normal!
What is the difference between light and dark rosins?​
Violin and viola players tend to use light rosin – it’s harder for the bow hair and produces a smoother sound. Importantly it’s also less likely to become too soft in hot and humid climates, so this may be your primary reason for choosing a lighter rosin.
Darker rosins are used by cellos and double bass players as it is softer and stickier and therefore gives more friction on those instrument’s thicker strings. Dark Rosin also usually produces a richer, warmer tone, but that’s very much down to personal choice. Always buy instrument specific rosin, though, especially if heat and humidity are a consideration.
How often should you rosin a bow?
Violinists typically need to re-apply violin rosin every four to six hours of playing. Don’t worry about timing it though; when you need to apply more, the bow will start slipping around the strings more than normal, and the sound changes.
If in doubt, just add a small couple of strokes every few days.
Do I need to do anything to a new rosin cake?
Yes! You’ll see the surface of the rosin is nice and glossy. We actually want to make it easier to glide your bow along the rosin; so carefully grab a knife or fork, and score the rosin so get it a bit scuffed. Then you’re ready to rock – or play your Paganini – whatever your preference is!
How tight should the bow be?
This is a difficult question to answer that all beginner string musicians grapple.
Firstly, be careful to not over-tighten the bow; it can cause the bow to snap.
Under-tighten and you’ll feel it challenging to produce a decent sound on the instrument. If you notice the strings meeting the wood of the bow (through the hair) – this is a clear case of your bow being not tight enough.
Summary
Over time, applying rosin will become second nature, and something you’ll do without thinking about. Buy a reputable brand of rosin – we recommend the MoreYes in large – it’s easy to hold, is low dust, eco friendly, and is large enough to hold steady.
Finally, do remember; little and often is the way to go!
