1. I see that there are three kinds of ANDREA rosin each for violin, viola, and Cello; Orchestra, Solo, and A Piacere. What are the differences between them?
Solo rosin provides powerful sound projection, yet it does not compromise on the sensitivity for the soloist. It is also very forgiving without the “sound cracks” on the strings under a high amount of bow pressure. You will not be overpowered in the orchestra. You will feel the immediate change in your sound.
Orchestra rosin is formulated to provide more blending and warmer sound - without compromising on clear bow articulations - for the player to create a better ensemble. Some soloists prefer the orchestra rosin for the sound color.
A Piacere has the exact same formula as the Tartini “GREEN” which was introduced in 2002. One of the secret ingredients in A Piacere helps the bow hair to make optimum contact to the strings and provides the effortless bow control with even sound production. This rosin will get the most out of your instrument and add that extra something you had with Tartini “GREEN.” The previous admirers have described the rosin as “Silkier sound.”
Now, choose your style. It is only a matter of taste.
2. Do you make ANDREA rosin for double bass?
There isn't ANDREA rosin specifically formulated for double bass. However, the ANDREA rosins for cello are highly recommended for use by double bassists.
3. Is it necessary to scratch the shiny top surface of the rosin with a sharp object to start off?
It is not necessary. Just simply start rubbing at the frog of the bow with a bit more pressure and you will see the shiny surface giving up and powderising. Make sure you don't put too much rosin or it will cake up on the strings.
4. How many swipes of ANDREA rosin do you need?
ANDREA rosin is manufactured with a sophisticated formula, and only 4-5 full bow length swipes will be enough to draw optimum performance.
5. Is it OK to mix ANDREA rosin with other rosins?
It is recommended not to mix it with other rosins. However, it does not cause any negative effects if mixed.
6. I see some small bubbly spots on the rosin. Is it normal?
After the hot liquid rosin is poured into the mold, some bubbles are too stubborn to come all the way up to the surface of the rosin during the cooling process. However, it does not result any negative effects on its quality of performance.
