If you happen to pick up one of Thomastik-Infeld’s new rosins for violin, viola, and cello, it may very well be that you’ll find it’s better traveled than you are. The waxes and resins therein were sourced from five different continents, after all. It’s also rather attractively packaged in a metal container: two pieces (one “regular” rosin, one “booster”) in each, closed with a magnetic mechanism.

The two-step customizable rosin is made to get the most out of Thomastik-Infeld’s strings, intended to support “focus, attack, and brilliance” while adding a dash of color. Violinist and project manager Stojan Jovanovic, in a product video, suggests swiping the regular rosin over the bow hair twice (in both directions) and the booster once. The booster, he says, will enhance your grip and response, but overdoing it could inhibit projection. Overall, the company’s new offering is designed to work in a variety of climates and will soon be available for bassists as well.
