Gudrun Lund started playing the piano, violin and viola as a little girl. She travelled with her family to the US, where she taught and performed many private concerts. After she returned to Denmark she was so inspired that she started composing her own works in 1976. In 1983 she travelled to the US again with support from the Danish Composers' Society and here she composed a work for the Harvard University Wind Ensemble. In Denmark she was supported by Women in Music, who commissioned works and helped her with many premieres. A lot of Lund's works are composed for unusual instrumentations as a result of commissions from various ensembles. Her music is inspired by Neoclassical composers such as Igor Stravinskij, but also the Carl Nielsen tradition. In 2005 Lund was appointed chairman of the Academy of the third Age, which is a society for active seniors.
