Heidi Parviainen (born 8 March 1979) is a Finnish professionally educated classical lyric soprano and a singing teacher. She is best known from her cinematic metal band Dark Sarah and as the former lead singer of Finnish power metal band Amberian Dawn. Before working with Amberian Dawn, she played keyboards and provided background vocals for a band called Iconofear.
Heidi's musical history started quite early in a children's music playschool. Later on, at a primary school, she went to a music-oriented class. She started taking piano lessons at the age of 11, but soon she said it became very clear that she wanted more than just classical piano playing. After various teachers, she quit taking piano lessons and has played by herself. At the age of 14, she started classical singing studies in a music institute with the diploma singer Raisa Lahtiranta. During more than ten years she had also sung in various choirs and ensembles.
