Gudrún’s voice is a lyric mezzo-soprano voice, which in earlier times would have been classified as a second soprano voice. Her wide vocal range allows her to sing repertoire ranging from music written for alto to soprano. Gudrún performs regularly in recital, with piano, guitar and ensembles. Her repertoire ranges from Sephardic Songs in the 15^th century to premieres of new works by international composers. Her recital programmes typically feature songs in English, French, German, Italian, Catalan, Galician, Russian, Latin, Basque, Danish, Norwegian and Swedish, with a special emphasis on repertoire in Icelandic and Spanish.
