"Love of My Life" is a song by the British rock band Queen from their 1975 album A Night at the Opera.
After Queen performed the song in South America in 1981, the version from their live album Live Killers reached number 1 in the singles chart in Argentina and Brazil, and stayed in the charts in both countries for an entire year.
Mercury wrote it on the piano and guitar first, and May rearranged the song for acoustic 12-string guitar for live performances, also lowering the key by a minor third. May contributed occasional guitar phrases to the original recording and played the swooping harp glissandos by pasting together multiple takes of single chords.
Background
Queen spent a month during the summer of 1975 rehearsing in a barn at what would become Ridge Farm Studio in Surrey. The group then had a three-week writing and rehearsing session in July in a rented house near Kington, Herefordshire before recording began. From August to September 1975 they began to record the song at Rockfield Studios in Monmouthshire.
