Ruth Wilhelmine Meyer is a distinctive voice artist, multi-vocalist, and composer who explores her instrument to create music through vocal timbres with different ranges of expression and colour. Her music free of genres is filtered through several genres and stylistic expressions that range from classical vocal tradition, selected ethnic traditions including throat singing, Norwegian folk music, multiphonics, and pure noise music. Her voice range is from 32 Hz to 2800 Hz, almost 7 octaves. This expression makes her popular for concerts, stage productions, film music, sound installations, and recordings all over the world. With her multi-expressive vocal expression, she creates sound worlds from the realistic to the unrealistic, the expected and the unexpected, and the sound becomes the narrator. She collaborates worldwide with instrumentalists and singers from various genres and cultures. She is the vocal soloist in the World Orchestra/Warsaw under the direction of Grzech Piotrowski and other main collaborators are jazz pianist Helge Lien and organist/composer Nils Henrik Asheim.
