No cause was announced, but her longtime personal manager, Michael Glynn, said she had been suffering from a heart ailment and lung disease.
Page helped bring country music to a broader audience in the late 1940s and early 1950s with smooth, elegantly produced recordings epitomized by The Tennessee Waltz," the simply expressed and achingly emotional tale of a woman who loses her sweetheart to an old friend at a dance: I introduced her to my loved one, and while they were dancing, my friend stole my sweetheart from me."
It spent 13 weeks at No. 1 in Billboard in 1950, becoming one of the biggest hits of all time and selling more than 6 million copies, according to Joel Whitburn's Pop Memories 1890- 1954." She landed nearly 100 records on the Billboard singles chart from 1948 through 1970, also including (How Much Is) The Doggie in the Window," Old Cape Cod," Allegheny Moon," and, in her final Top 10 hit, the title song from the 1965 film Hush ... Hush, Sweet Charlotte."
Following a lead established by Tennessee singer Eddy Arnold in the late 1940s, Page was able to reach beyond rural Southern audiences with recordings that betrayed no trace of her native Oklahoma twang and replaced steel guitars, fiddles and other traditional country instrumentation with a muted trumpet and orchestral violins as accompaniment.
According to Page's entry in the Contemporary Musicians reference work, In the decade immediately following World War II but preceding the flowering of rock and roll, a set of star vocalists rose to the top of popular music, displacing the big swing bands that listeners and dancers had favored during the war era. This was really the point of origin for the music industry as we know it today: Record-label executives wrested the power in the industry from the old publishing firms and carefully cultivated the careers of singing stars, assiduously managing their public images. One of the very biggest of these stars was Patti Page."
