Soleares is often referred to as the mother of all flamenco forms because so many other important forms are derived from it.

It may be more accurate to think of soleares as the most flamenco of flamenco forms. All the elements of soleares, including its 12-count compás with an irregular beat structure, its Andalusian cadence, and its melodic and melissmatic gestures are unique to flamenco.

​Soleares first evolved in the late 18th Century from a dance form called Jaleo. As it evolved through the 19th Century, it took on a more solemn, cante jondo character, probably due to its inclusion in the Cafés Cantantes as a featured song and flamenco dance. Various forms of soleares developed associated with different cities and individuals. At the beginning of the 20th Century new forms were derived from soleares, including bulerías and soleá por bulerías.

​A common belief is that the word soleares is derived from the Spanish word soledad, or sorrow. Sorrowful, unrequited love is a main theme of the letras, along with other bittersweet lamentations.
