Beyoncé Giselle Knowles

• Music and voice
Knowles' music is generally contemporary R&B, but she also incorporates pop, funk, hip hop, and soul into her songs. While she almost exclusively releases English songs, Knowles recorded several Spanish songs for Irreemplazable and the re-release of B'Day. Prior to recording these, Knowles was coached phonetically by American record producer Rudy Perez.
Since Destiny's Child, Knowles has artistically been involved in her career. She received co-writing credits for most of the songs recorded by the group, as well as her solo efforts. Known for writing personally driven and female-empowerment themed compositions, Knowles has stated that having Jay-Z in her life has changed a few of her thoughts about how men and women relate to one another, which helped her transition from writing songs such as "Independent Women" and "Survivor" to man-tending anthems such as "Cater 2 U", in which she sings about bringing him slippers and drawing his bath. Some of her songs are autobiographical, which she has admitted are taken from personal experiences, as well as her friends'. Knowles has also received co-producing credits for most of the records in which she has been involved, especially during her solo efforts. However, she does not formulate beats herself, but typically comes up with melodies and ideas during production, sharing them with producers. Knowles was recognized as a songwriter during the run of Destiny's Child in the 1990s and early to mid-2000s. She won the Pop Songwriter of the Year award at the 2001 American Society of Composers, Authors, and Publishers Pop Music Awards, becoming the first African-American female and second female songwriter of all time to accomplish the feat. Knowles received songwriting credits in a single year for co-writing "Irreplaceable", "Grillz" and "Check on It", all of which reached number one on the Billboard Hot 100, the only woman to have written three songs which went to number-one in the same year since Carole King did it in 1971 and Mariah Carey in 1991. In terms of credits, she is tied with Diane Warren at third with nine number-one singles.
Knowles possesses a mezzo-soprano vocal range that spans more than three octaves. She has often been identified as the centerpiece of Destiny's Child. Jon Pareles of The New York Times commented that she has the voice that defines the group, writing that her voice is "velvety yet tart, with an insistent flutter and reserves of soul belting". Other critics praise her range and power. In reviewing her second album B'Day, Jody Rosen of Entertainment Weekly wrote "Beyoncé Knowles is a storm system disguised as a singer. On her second solo album, B'Day, the songs arrive in huge gusts of rhythm and emotion, with Beyoncé's voice rippling over clattery beats; you'd have to search far and wide—perhaps in the halls of the Metropolitan Opera – to find a vocalist who sings with more sheer force ... No one—not R. Kelly, not Usher, to say nothing of her rival pop divas—can match Beyoncé's genius for dragging her vocal lines against a hip-hop beat." Chris Richards of The Washington Post wrote, "Even when she's coasting, she soars above her imitators. It's all in her voice—a superhuman instrument capable of punctuating any beat with goose-bump-inducing whispers or full-bore diva-roars. Smitten, scorned, amorous, antagonistic—Beyoncé sings from all of these vantage points with undeniable virtuosity." Knowles has often been criticized for oversinging. A prominent employer of melisma, she earns frequent comparison to such artists as Mariah Carey, whose vocal embellishments have been known to detract from the melody of their songs.
