Rosin, as one of the indispensable violin accessories, is very important, but its importance is often overlooked. Different rosins have amazing and huge differences in all aspects of sound and performance.
The raw material of rosin is called rosin, which is collected from fir and pine trees. The source of raw materials, the composition of finished products, the measurement of ingredients, and the production procedures are kept confidential by each manufacturer.
The characteristics of different raw materials, the different ingredients mixed in post-production and the production methods all play a decisive role in the performance of rosin.
The characteristics of rosin and how to use it:
Rosin is divided into dry and hard, and sticky and soft. Generally speaking, the violin is more suitable for dry and hard, while the cello is suitable for sticky and soft.
Generally speaking, if it is a chamber music or a recording studio, a softer rosin is more suitable. On the contrary, on the stage, especially outdoors, a harder rosin is more suitable. From a geographical point of view, tropical regions are more suitable for harder rosin, while colder regions are more suitable for softer rosin.
When smearing rosin on the bow hair, if the rosin is too hard to apply the bow hair (especially after new molting), you can put a little rosin powder on the cloth, and first use a bow to pull on the cloth like a violin few times. You can also scratch some cracks on the surface of the rosin to make it easier for the bow hair to bite the rosin.
Points to note when using rosin:
The rosin on the bow hair melts at high temperatures.
For cleaning the rosin layer on the strings, it is best to use cotton cloth, never use alcohol.
After the rosin is used up, wrap it up well.
Rosin is easy to shrink and deform in places that are too dry, it is easy to stick in places that are too humid, it is easy to melt in places that are too hot, and it is easy to crack in places that are too cold.
