Sentimental ballads had their origins in the early Tin Pan Alley music industry of the later 19th century.[5] Initially known as "tear-jerkers" or "drawing-room ballads", they were generally sentimental, narrative, strophic songs published separately or as part of an opera, descendants perhaps of broadside ballads. As new genres of music began to emerge in the early 20th century, their popularity faded, but the association with sentimentality led to the term ballad being used for a slow love song from the 1950s onwards.[6]
