A torch song is a sentimental love song, typically one in which the singer laments an unrequited or lost love, either where one party is oblivious to the existence of the other, where one party has moved on, or where a romantic affair has affected the relationship. The term comes from the saying, "to carry a torch for someone", or to keep aflame the light of an unrequited love. Tommy Lyman is said to have created the slang when he announced one night: "My famous torch song: 'Come To Me, My Melancholy Baby' ". 
Torch singing is more of a niche than a genre, and can stray from the traditional jazz-influenced style of singing, although the American tradition of the torch song typically relies upon the melodic structure of the blues. Some examples of torch songs are "Can't Help Lovin' Dat Man" (1927), "Lili Marlene" (1938), "One for My Baby" (1943), "The Man That Got Away" (1954), "Ne me quitte pas" and "Here's That Rainy Day" (1959), "By the Time I Get to Phoenix" (1965), "Losing My Mind" (1971) and "And I Am Telling You" (1982).
Female singers of the pop vocal tradition are referred to as torch singers when their repertoire consists predominantly of material of that nature. Though torch songs were usually previously associated with female singers, in recent years the term has also been applied to male singers, most notably Frank Sinatra.
