Helgi Pétursson (1962) graduated from the Department of Theory and Composition at the Reykjavík Conservatory of Music where his teachers in composition were Þorkell Sigurbjörnsson, Atli Heimir Sveinsson and Þorsteinn Hauksson.
Later he also completed an MA degree in Microtechnology in Music Education from the University of Reading, UK.

During Helgi's student years, quite a few of his works were performed in public, including electronic works and works by him
were also performed after he finished his studies, including the years when he was employed as a music teacher in Húsavík.

Helgi has for a very long time been very interested in electronic and computer music and also in computer technology in general, and he worked for several years as a computer programmer. After he retired as a working musician,
his composition was mostly stopped, but he picked up the thread again with the piece Blindfugl/Svartflug (Blindbird/Blackflight). Blindfugl/Svartflug was written in June 2024 and is based on a poem of the same name
by Gyrðir Elíasson from 1986 which Helgi reads live in its entirety throughout the piece. The idea for this piece is very old because it had been Helgi's dream to make this piece almost ever since he heard Gyrðir read the poem on the Icelandic radio soon after it was released. It had a very strong effect on the him as composer. The piece can be said to be an attempt to emphasize the impressions and moods that the poem evokes using a varied sound world and thus create a kind of sound painting of the poem.
