KAPLAN Premium rosin by D’Addario

Premium sound control for demanding string players

KAPLAN Premium Rosin by D’Addario is one of the finest rosin formulations on the market, developed specifically for violin, viola and cello. The carefully balanced recipe provides clean, low-dust application and optimal bow grip, delivering a warm, clearly focused tone with minimal unwanted noise.

The slim, modern case can be opened comfortably with one hand. Inside, a rotating tray allows the rosin to be distributed evenly on the bow hair – ideal for consistent performance and a professional playing feel in daily practice, on stage or in the rehearsal room.

KAPLAN Premium Rosin is made from high-quality natural ingredients and is cast and packaged under strict quality control at D’Addario’s facilities in New York (USA). The formula is based on the original recipe of Ladislav Kaplan and combines tradition with modern manufacturing quality.

Light & dark formulations

KAPLAN Premium Rosin is available in two formulations so players can fine-tune grip to their instrument, climate and playing style:

• Light: slightly harder with less grip – ideal for violin and viola or for players who prefer fast response and a slightly lighter feel.
• Dark: slightly softer with more grip – ideal for cello or whenever extra traction is needed for powerful, projecting tone.

Note: The colour of the rosin (light/dark) is only a guideline. Both softer and harder rosins can be produced in different colours – what really matters is grip, feel and sound.

Which rosin type is right for me?

As a general rule:

• Players of lower instruments (e.g. cello) often prefer softer/darker rosins, as they provide more grip to set the thicker strings into motion reliably.
• Violin and viola players often choose lighter/harder rosins, which support fast bow strokes and an immediate response.

Application tips – for best sound & a clean instrument

Many players use too much rosin, which can lead to a harsh, grainy sound and visible build-up on the top and the strings. With KAPLAN Premium Rosin this is easy to avoid:

• At the start of a practice or playing session, 3–4 strokes on the bow hair are usually enough.
• After playing, wipe the instrument and strings with a soft cloth to remove excess rosin.
• If the grip decreases, apply rosin sparingly and as needed instead of using large amounts too often.

This way, your sound remains clear, warm and defined, and your instrument stays well protected – exactly what KAPLAN Premium Rosin is made for.
