Solveig Slettahjell (pronounced: Sul-vay Shlet-I-Yell) was born in Bærum near Oslo in 1971 and grew up in the small town of Orkanger near Trondheim. As her father was a pastor, she grew up in church. She sang in choirs from the age of 7 and began accompanying various youth and gospel choirs on the piano from the age of 13. She also sang and played her own versions of hymns, negro spirituals, Norwegian religious folksongs, as well as her own compositions.

Studies Solveig studied classical piano and singing at a secondary school for music in Trondheim, before going on to jazz studies at the Norwegian Academy of Music in 1992. Here she met Sidsel Endresen, who was her teacher from 1993 and until Solveig finished her master’s degree in 2000. Her final exam consisted of a thesis on the rhythmic aspects of phrasing and a concert, which was the beginning of the Slow motion concept.
