Aaliyah had the vocal range of a soprano. With the release of her debut single "Back & Forth", Dimitri Ehrlich of Entertainment Weekly expressed that Aaliyah's "silky vocals are more agile than those of self-proclaimed queen of hip-hop soul Mary J. Blige." In her review for Aaliyah's second studio album One in a Million Vibe magazine, music critic Dream Hampton said that Aaliyah's "deliciously feline" voice has the same "pop appeal" as Janet Jackson's. Aaliyah described her sound as "street but sweet", which featured her "gentle" vocals over a "hard" beat. Though Aaliyah did not write any of her own material, her lyrics were described as in-depth. She incorporated R&B, pop and hip hop into her music. Her songs were often uptempo and at the same time often dark, revolving around "matters of the heart". After her R. Kelly-produced debut album, Aaliyah worked with Timbaland and Missy Elliott, whose productions were more electronic. Sasha Frere-Jones of The Wire finds Aaliyah's "Are You That Somebody?" to be Timbaland's "masterpiece" and exemplary of his production's start-stop rhythms, with "big half-second pauses between beats and voices". Keith Harris of Rolling Stone cites "Are You That Somebody?" as "one of '90s R&B's most astounding moments".
Aaliyah's songs have been said to have "crisp production" and "staccato arrangements" that "extend genre boundaries" while containing "old-school" soul music. Kelefah Sanneh of The New York Times called Aaliyah "a digital diva who wove a spell with ones and zeroes", and writes that her songs comprised "simple vocal riffs, repeated and refracted to echo the manipulated loops that create digital rhythm", as Timbaland's "computer-programmed beats fitted perfectly with her cool, breathy voice to create a new kind of electronic music." When she experimented with other genres on Aaliyah, such as Latin pop and heavy metal, Entertainment Weekly's Craig Seymour panned the attempt. While Analyzing her eponymous album British publication NME (New Musical Express) felt that Aaliyah's radical third album was intended to consolidate her position as U.S.R&B's most experimental artist. As her albums progressed, writers felt that Aaliyah matured, calling her progress a "declaration of strength and independence". ABC News noted that Aaliyah's music was evolving from the punchy pop influenced Hip hop and R&B to a more mature, introspective sound on her third album. Stephen Thomas Erlewine of AllMusic described her eponymous album, Aaliyah, as "a statement of maturity and a stunning artistic leap forward" and called it one of the strongest urban soul records of its time. She portrayed "unfamiliar sounds, styles and emotions", but managed to please critics with the contemporary sound it contained. Ernest Hardy of Rolling Stone felt that Aaliyah reflected a stronger technique, where she gave her best vocal performance. Prior to her death, Aaliyah expressed a desire to learn about the burgeoning UK garage scene she had heard about at the time.
