CECILIA Rosin — the finest premium formulas for violin, viola, cello & bass
Low-dust, long-lasting professional rosins crafted in New York by Peter Bahng, Cremona in America. Choose the response you want — from round and warm to bright and projecting.
“Does rosin really make a difference?” "Yes!"
Rosin is what helps produce the sound when your bow makes contact with the string. An analogy would be how the tyres you put on your car change the way it drives and performs. If you have exhausted other options, such as set-up, and are still not satisfied with your sound, then we’d strongly recommend investigating the impact a professional quality rosin can have.
CECILIA rosins are all developed for professional use. They are low-dust. Only a small amount is needed (do not over-rosin your bow with CECILIA), which means they are economical and will last a long time. Each rosin type has been designed with different players and their needs in mind by a professional violinist and has been extensively tested in different countries.
During 2020, Peter Bahng changed the name of the rosins from ANDREA to CECILIA, offering the original, unchanged formulas. Orchestra rosin was discontinued.
CECILIA Signature Formula
Full, rich and expressive tones without excessive bite — made using a new liquid-blending method for purity and freshness. A small amount goes a long way.
CECILIA Sanctus
Developed for CECILIA’s 10th anniversary — a unique two-in-one cake. The hydrogenated base resists oxidation for consistent performance over its long life.
CECILIA Solo
Maximum projection with clear articulation, yet forgiving under pressure without “cracking”. Ideal for big halls and standing out in an ensemble.
CECILIA A Piacere
A warmer, rounder tone with refined, blended articulation. Especially good for orchestral work; offers slightly less projection than Solo for a silkier sound.
CECILIA Bass Rosin — Softer & Firmer
Designed for dependable grip and consistent traction across temperatures — unlike many bass rosins, CECILIA does not dry out.
CECILIA Rosin Spreader (included with Full size)
Attaches under the rosin base to distribute particles evenly. Thoroughly settles rosin between the bow-hair strands after a fresh rehair, evens out application, and removes excess — improving response and keeping dust down.

The history of Cecilia Rosin — from inception to the present day
From an inspired workshop experiment to a trusted professional staple, here’s how Cecilia Rosin grew into a modern collection loved by string players worldwide.
Where curiosity met craft
In 1998, a young Peter Bahng was practising violin in his father Andrea’s workshop. Andrea was immersed in varnish research—often sap-based—while Peter began testing rosin variations, exploring shared ingredients and refining formulas to make playing easier and sound better.
The first launch
After many small-batch experiments, Peter found a compound that enhanced both ease and tone. While he returned to the Cleveland Institute of Music, his parents helped bring the original Tartini rosin to market in 2001—and a legend was born.
Growing pains & lessons
Subsequent business changes led to a rename from Tartini to Andrea, with production happening at two companies using different formulas. Quality inconsistencies followed, and by 2007 production of Andrea rosins ceased for a time.
Back to the original feel
Peter—then a professional violinist in New York—founded Cremona in America and, with his mother Cecilia, revived the original Andrea formula without compromise for professional players. Over the next decade he expanded the range, ultimately producing 200,000+ Andrea rosins.
A name that honours a legacy
Following Cecilia’s passing in 2019, Peter renamed the brand CECILIA in her honour—aptly sharing a name with the patron saint of musicians. From early 2020 onward, production moved entirely under the CECILIA name. Formulas did not change.
Note: Orchestra rosin has been discontinued; Solo, A Piacere, and Sanctus continued alongside the flagship Signature Formula.
Signature sound, consistent performance
Today’s CECILIA range focuses on expressive, reliable response across climates and playing styles, including Signature Formula, Solo, A Piacere, Sanctus, and dedicated Bass rosins.
Essence: refined grip, long life, and musical clarity—engineered in New York with a player’s ear.
