Founded in 2009, Cecilia (formerly Cremonia in America) rosin has formulated a perfect blend for violin, viola, and cello. Each Cecilia brand rosin comes in four different formulas: Signature Formula, Solo, A Piacere, and Sanctus.

Sanctus: developed to combine two rosin formulas in a single cake. The appearance of each Sanctus rosin is truly unique. The outer ring formula gives smooth bowing experience with a focused sound on the strings, and the softer center formula kicks in when the player demands more power and gutsiness from their instrument.
