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.

Solo Formula: a long-time popular formula with strong grip that gives a very stable bowing sensation. The formula focuses on providing maximum projection as well as clear articulation. It is also forgiving under high bow pressure on the strings without the sound cracking.
