Tracy Elizabeth Dahl (born 13 November 1961) is a Canadian coloratura soprano who has performed in opera houses and on concert stages around the world. Known for her agility and vocal range, Dahl's voice has been described as "filled with sunshine, rainbows and laser light". Alongside her performing career, Dahl teaches voice at the University of Manitoba Desautels Faculty of Music, and conducts masterclasses and workshops across North America. She lives in Winnipeg, Manitoba with her husband and two children.
Born in Winnipeg, Dahl began voice lessons at 12, and seemed destined for a career in musical theatre. In 1979 and 1980, she studied drama and musical theatre at the Banff Centre. After a successful debut as Barbarina in Manitoba Opera's 1982 production of Mozart's Le Nozze di Figaro, Dahl changed her focus to opera. In 1983, she studied opera at the Banff Centre, and the Banff Academy of Singing in 1984 under the guidance of Mary Morrison and Martin Isepp. In 1985, she participated in San Francisco Opera's Merola Opera Program, and soon began a career in opera.
In 1987, Dahl made her European debut at Aix-en-Provence, performing the role of Blondchen in Mozart's Die Entführung aus dem Serail. Also in 1987, she made her American opera debut in The Tales of Hoffman at the San Francisco Opera, singing the role of Olympia opposite Plácido Domingo. In 1991, in the place of an indisposed singer, she sang the role of Adele in Johann Strauss Jr.'s Die Fledermaus at the Metropolitan Opera. She also performed as Florestine in the premiere of John Corigliano's Ghost of Versailles at the Metropolitan Opera in 1991, and again in 1995.
