Rosin is a sticky substance which is applied to the bow of an orchestral instrument. The consisency of the rosin helps create friction between the bow and the instrument’s strings, which allows for easier playing and a stronger sound.
Rosin is made of tree resin, which is like sap. Resin is a sticky liquid which is usually derived from pine trees. To make rosin, the raw resin is heated until it becomes solid. The end product, known as rosin, looks glassy in texture but is actually brittle and can break somewhat easily.
Rosin and resin are different in that rosin is the product of heating resin. Natural resin, extracted from trees, is a sticky, viscous liquid. However, once the resin is heated, it becomes a solid called rosin, which is suitable for application to bows.
Rosin comes in Light and Dark options. The main difference between light and dark is the melting point, which translates to being either more or less sticky.
Dark rosin has a lower melting point and feels stickier. The extra stickiness helps players grip the string with the bow hair, making it great for people who play instruments with wider/longer bow hair (i.e., cello or viola).
Light rosin is less sticky, making it easier for people who have lighter bows or who might not need the extra leverage on their bow. This is good for the upper string players, like violin or viola.
The process of making rosin is pretty straightforward. Tree resin is collected by cutting and tapping a tree. The resin is then heated, sometimes in combination with other ingredients, which may affect the color or material quality of the resin. The final result is a solid piece of rosin which can be applied directly to the bow.
