Colla Voce chamber choir was founded in 1999.  The SATB choir is made up of singers from the Quarry Bank area of the             Black Country in the West Midlands.

Our love of choral classical music from a variety of styles and genres has lead to the choir having a rich and varied repertoire.  The choir sings a number of concerts throughout the year to share our love of music with our audiences.

Musical Director, Mariana Rosas, took up her post in

September 2019.  She brings a fresh energy to the choir, and has introduced us to new music from around the world.

She also coordinated a student lead choir in the outskirts of Buenos Aires as part of a Voluntary project.

Mariana has worked as guest conductor in Argentina, Denmark, Canada, Italy and Switzerland. In 2018 she moved to England with her husband to study at the University of Birmingham.  Since then she has studied and worked with Simon Halsey, Simon Carrington, Julian Wilkins, and Mike Seal, and has gained her Masters in Choral Conducting at the University of Birmingham.
