Upon completing his research in both music and structures, Per Hjort Albertsen returned to his hometown and dedicated himself to its music lifestyle, with particular focus on teaching. Albertesen graduated from Oslo Conservatory in 1946; his many instructors included Ralph Downes, Hanns Jelinek, Ludvig Nielsen, Arild Sandvold, Per Stenberg, and Svend Erik Tarp, with whom he researched in Norway, Austria, Britain, and Denmark. After functioning as an organist for 21 years (1947 – 1968) he lectured at Trondheim College or university (1968 – 1972), acknowledging the directorship of Trondheim conservatory in 1972. He provides written public, unaccompanied sacred and secular choral parts, orchestral suites, concertos, and functions for the piano. Several recordings of his compositions have already been released by main brands — his Concerto Piccolo for violin and strings by Hemera Music and several his organ choices by Simax, all in the 1990s.
