Carlsson Swedish Double Bass Rosin for Bowing



Fresh bass rosin is a necessary Performance Accessory for Arco Bass Play

Carlsson Swedish Double Bass Rosin

  • Carlsson’s is a Hard Rosin used by orchestra pros.
  • Its color is dark brown.
  • Made in Sweden by the Hart Family for many generations.
  • Season for use is All Weather in most climates. Because Carlsson’s bass rosin is another of the Hard Rosin Formulas, we sometimes rosin our new bass bows with Carlsson’s first, then layer over the top with softer rosin like Pop’s. This hard bass rosin under softer rosin combo gives brand new bow hair noticeably better grip much more quickly. Later, The Carlsson’s will absorb much of the extra moisture in the Pop’s so the remaining rosin in the bow dries more quickly, a real plus in our Bow Trial Room, where quick refurbishing of bows is crucial to accurate, effective testing.
  • Other names for this double bass rosin are Carlsson arco bowing rosin, Carlsson bass bow rosin, Carlsson orchestra bass rosin, Carlsson rosin for bass bowing, Carlsson’s, blue box bass rosin, kolophonium (in Germany), or colophonium (in France.)
  • Carlsson’s Package is a metal foil-wrapped cylindrical cake stored in a plastic flip-top storage container.
  • Endorsed by orchestra professionals worldwide.
  • We order Carlsson’s Rosins 10 times each year to insure Lemur has the freshest cakes from the most recent batch at all times!

How to use Carlsson Bass Rosin

A cake of Carlsson Rosin is wrapped in a metallic foil cylindrical cup. Just peel one side of the foil down about one-quarter inch at a time and …

Draw the bow across the surface of the cake with long downward strokes. The bow hair should be tensioned. Do not “scrub” the hair back and forth across the cake, which can damage bow hair. Draw the bow across the cake three or four times to apply the rosin.

Remember, new bow hair will absorb a surprisingly large amount of rosin. The first time application of rosin will take much more effort than subsequent applications. During extended periods of play, re-application of rosin may be necessary.

The purpose of bass bow rosin is to increase traction of bow hair on the string. The choice of how much rosin is needed to get a good grip is very much a players preference, but keep in mind that too much rosin will slow the bow stroke and dampen tone. Too little rosin will result in the bow ‘sliding’ too much to properly start (and control) the string’s vibration.

Softer rosin goes on more quickly than harder rosin. Softer rosin builds up more quickly also, so take care not to over apply. Warmer weather and higher humidity make harder rosin easier to apply. Hard rosin does not produce as much dry rosin debris, nor does it gum up the bow hair as quickly as softer rosin.

Store rosin in a cool, dark place so it does not get runny and lose its shape. Use the container it comes in. Rosins packaged in cloth wraps must be kept cool, or they will run. Foil containers, cardboard or plastic tubs offer the most protection for retaining the rosin’s form. Do not store rosin in a hot car, on a windowsill, or near other heat sources.

After play, allow rosin to dry in the bow hair, then tap the hair gently to shake the ‘dust’ out of the bow hair. Wipe the hair-side of the stick with a soft cloth to eliminate rosin build-up on the wood. Ditto, wipe the frog down after play. The oils and perspiration on hands can discolor the frog, wire wrapping, and especially pearl or shell trim.
