tenhammar was born in Stockholm, and was the brother of architect Ernst Stenhammar. He received his first musical education in Stockholm. He then went to Berlin to further his studies in music. He became a glowing admirer of German music, particularly that of Richard Wagner and Anton Bruckner. Stenhammar himself described the style of his First Symphony in F major as "idyllic Bruckner". He subsequently sought to emancipate himself and write in a more "Nordic" style, looking to Carl Nielsen and Jean Sibelius for guidance.
