In 1935, he enrolled in the theoretical composition faculty at Baku Conservatory, studying under Uzeyir Hajibeyov and the Latvian-born Leopold Rudolf, a student of Sergei Taneyev.

During his lifetime, Hajiyev composed eight symphonic works plus the heroic-patriotic opera "Vatan" (Motherland), which he wrote with Gara Garayev in 1944.

Hajiyev served briefly as Artistic Director of the Baku Philharmonic Orchestra (1947–48) and was appointed to the staff of the Azerbaijan State Conservatory.
