Destiny's Child recorded R&B songs with styles that encompasses urban, contemporary, and dance-pop. In the group's original line-up, Knowles was the lead vocalist, Rowland was the second lead vocalist, Luckett was on Soprano, and Roberson was on alto. Knowles remained as the lead vocalist in the group's final line-up as a trio, however, Rowland and Williams also took turns in singing lead for the majority of their songs. Destiny's Child cited R&B singer Janet Jackson as one of their influences. Ann Powers of The New York Times described Destiny's Child music as "fresh and emotional ... these ladies have the best mixes, the savviest samples and especially the most happening beats." In the same publication, Jon Pareles noted that the sound that defines Destiny's Child, aside from Knowles' voice, "is the way its melodies jump in and out of double-time. Above brittle, syncopated rhythm tracks, quickly articulated verses alternate with smoother choruses." The group usually Harmonize their vocals in their songs, especially on the ballads. In most instances of their songs, each member sings one verse and chimes in at the chorus. In their third album Survivor (2001), each member sings lead in the majority of the songs. Knowles said, "... everybody is a part of the music ... Everybody is singing lead on every song, and it's so great—because now Destiny's Child is at the point vocally and mentally that it should be at." Knowles, however, completely led songs like "Brown Eyes" and "Dangerously in Love". The group explored their lyrics to man-to-woman relationship, sisterhood and female empowerment anthems.
