Finding the right professional rosin for a given stringed instrument can be a “sticky” effort. Professional orchestra players know that there is no one rosin that fits all instruments. Violin’s and Viola strings need less frictional energy transfer from the bow, while larger instruments, Cello and the Double Bass demand more energy transfer to vibrate the heavier string mass, however too much tack (stickiness) and the tonal quality can be dampened. Professional Double Bass players often carry multiple rosins depending on the weather, and humidity. Many carry alcohol to “thin” harder rosins for application in certain conditions. Terms are often used to identify rosins, like hard, soft, extra soft, etc. Cello players have had little choice in rosins, and often use violin rosin. Double bass players typically prefer a softer rosin with more tack for strong low frequency and higher amplitude sound, while other musical pieces and solos may call for a more firm rosin with less tack. Personal preferences in rosins vary from person to person. For the first time a new concept in rosins for all players is available. The Salzman Symphony professional rosin series.
This unique series offers a range of rosins from a # 1 through a #10 with smooth transitions between each rosin for softness and tack. The figure above illustrates this new rosin scale for rosins, with 3 different rosins for Violin/Viola, three for Cello, and 4 for the Double Bass. The Salzman rosin scale used for this rosin series ranges from #1, hard/dry light (low tack) to the most soft and sticky (high tack) rosin #10. Numbers in between 1 and 10 follow a slightly exponential scale.
