"I Will Always Love You" is a song written and originally recorded in 1973 by American singer-songwriter Dolly Parton. Written as a farewell to her business partner and mentor Porter Wagoner, expressing Parton's decision to pursue a solo career, the country single was released in 1974. The song was a commercial success for Parton, twice reaching the top spot of Billboard Hot Country Songs: first in June 1974, then again in October 1982, with a re-recording for The Best Little Whorehouse in Texas soundtrack. Whitney Houston recorded a soul-ballad arrangement of the song for the 1992 film The Bodyguard. Houston's version peaked at number one on the Billboard Hot 100 for a then-record-breaking 14 weeks. The single was certified diamond by the RIAA, making Houston's first diamond single, the third female artist who had both a diamond single and a diamond album, and becoming the best-selling single by a woman in the U.S. The song was a global success, topping the charts in almost all countries. With over 20 million copies sold, it became the best-selling single of all time by a female solo artist. Houston won the Grammy Award for Record of the Year in 1994 for "I Will Always Love You". The song has been recorded by many other artists including Linda Ronstadt, John Doe, Amber Riley, LeAnn Rimes, and Sarah Washington, whose dance version reached number 12 on the UK Singles Chart. Background and composition Country music singer-songwriter Dolly Parton wrote the song in 1973 for her one-time partner and mentor Porter Wagoner, from whom she was separating professionally after a seven-year partnership. She recorded it in RCA Studio B in Nashville on June 12, 1973. Author Curtis W. Ellison stated that the song "speaks about the breakup of a relationship between a man and a woman that does not descend into unremitting domestic turmoil, but instead envisions parting with respect – because of the initiative of the woman". The country love track is set in a time signature of common time with a tempo of 66 beats per minute.
