Cecilia is the continuation of the brand known for many years as Andrea Rosin. The formulas were developed by Peter Bahng in the United States. In 2026, Cecilia will be the standard for professional string players seeking maximum control, projection, and tonal purity.
Why professionals switch from Andrea to Cecilia
Cecilia builds on Andrea's beloved formulas, but with further refinements. The focus is on consistency, control, and an immediately audible effect on the sound.
- Handmade in the United States.
- Developed for soloists and advanced players.
- Immediate improvement of articulation and projection.
If you search for Andrea rosin, you're now looking for Cecilia. The philosophy and quality have been retained, and the formulas have been further developed.
The Cecilia formulas. From Signature to A Piacere.
Each Cecilia rosin has a distinct sonic purpose. You choose not based on your instrument, but on your playing style and desired response.
Cecilia Solo. For the soloist seeking maximum power.
Cecilia Solo is the most chosen formula for soloists.
- Very strong projection.
- Clear articulation at high stick pressure.
- Forgiving and stable.
Ideal for large halls and concerto repertoire.
Sanctus. The unique 2-in-1 resin for every playstyle.
Sanctus combines two properties in one block.
- Hard outer ring for grip and focus.
- Soft core for flexibility.
- Adaptable to dynamics and repertoire.
Suitable for musicians who frequently switch between styles.
The secret behind the sound. Handmade craftsmanship from New York.
Cecilia uses the Liquid Form Blending Method. Each ingredient is filtered and processed separately.
- High purity.
- Constant grip.
- Minimal noise and unwanted background noise.
Larger packages include a rosin spreader. This helps distribute the rosin evenly across the bow.
