Lars Bisgaard studied musicology at the University of Copenhagen followed by studies in music history and theory at the Royal Academy of Music in Copenhagen, where he graduated with a diploma in 1973, followed by a exam in music teaching in 1975. Later he continued his education at the Jutland Academy of Music, Aarhus, studying composition. His teacher was Per Nørgård, and he graduated with a diploma in 1981.
Between 1972-1981 he was absorbed in Per Nørgård's hierarchical musical theory and its connection with the symbolic world of astrology, as well as the Czech-American researcher of consciousness Stanislav Grof and his chartings of structures in the unconscious. On the basis of this, Bisgaard developed a tool for musical analysis, and its possible applications were demonstrated in the article "Musikalsk hermeneutik på hierarkisk grundlag - bidrag til en musikalsk fænomenologi" ("Musical hermeneutics on a hierarchical basis: contributions to a musical phenomenology", Danish Annual of Musicology 1985-86). He has taught music history and theory at the Institute of Musicology at the University of Copenhagen between 1975-82 and the same subjects at the Carl Nielsen Academy of Music, Odense between 1979-82. Bisgaard was also employed as a lecturer at the Academy of Music in Esbjerg between 1981-92, and since 1993 he has worked at the Royal Academy of Music, Copenhagen – becoming a lecturer there in 1995. Additionally, Lars Bisgaard also continues to develop the computer programme ‘HarmonianalyseTutor’ (Tutorial of harmonic analysis) for use in teaching the analysis of functional harmonics.
