Ruth Bieri is a freelance pianist, keyboard player and composer based in Zürich, Switzerland. For over 30 years, she has been heavily involved in music projects. She has played and continues to play in diverse formations at home and abroad as well as composing for film and theatre. In 1993, she founded Serpent (known today as Women in Music) in Zürich – the first ever rock, pop and jazz academy for women in the DACH countries – where Bieri provided vital impulses in her ten-year tenure as an instructor and academy director.
The common thread running through her musical career is her passion for combining music with images or language. Her extraordinary gift for spontaneously inventing and varying musical themes finds expression in her work as a live accompanist for silent films.
