Usher possesses a leggiero tenor vocal range of 3 octaves and 2 notes, and is considered to be "one of the most soothing in R&B". At the age of 13, he set the record for the longest note ever held by a child on Star Search, with 12 seconds. Usher's vocal coach since My Way, Jan Smith, cites him as "the single most gifted singer I’ve ever worked with in 26 years". On the dynamic 8701, Rolling Stone's Kathryn McGuire describes his vocals as "velvety" and "impressively adaptable" as it won him his first two Grammys as Best Male R&B Vocal Performance. With Confessions, Sasha Frere-Jones of The New Yorker notes him as "long on control and short on texture". He received another Grammy Award nomination in 2006 through a cover of Luther Vandross's "Superstar" he performed on The Oprah Winfrey Show in 2005. Here I Stand displayed his vocals as "agile" and "balletic", as well as his ability to "easily drift from wavering tenor to fine-tuned falsetto" that create emotions of urgency and burning according to Clover Hope of The Village Voice. On his One Night Stand: Ladies Only Tour in 2008, Lee Hildebrand of San Francisco Chronicle stated that "Usher's chest tones have a ringing, Gaye-like quality, and his high head tones suggest Prince's falsetto, but his frequent use of syllable-splitting curlicues owes much to Wonder. Usher is a stronger, more assured singer than he was a decade ago, though the melismas in his lower range sometimes meander off pitch. His falsetto tonality is more on target." Looking For Myself exemplified his vocal craft earning him positive acclaim as Gawker's Rick Juzwiak states "his vocal range is even more impressive than his emotional one" with emphasis on his falsetto being "something that sounds as natural as a speaking voice...he's the picture of grace against shrieking synths [...] His emotional range is vast enough to sell tenderness, lechery and wistfulness within minutes of each other". Regarding "Climax", his performance was lauded as "blistering" by Maura Johnston, and "hair-raising" by Jody Rosen, as he won Best R&B Performance in 2013. "There Goes My Baby" and "Dive" are also commended as showcase standouts of his "superior R&B vocal range" by Consequence of Sound's Ryan Hadfield, and MadameNoire's Brande Victorian. For Hard II Love, Jon Pareles of The New York Times commented "a genuinely expressive voice that encompasses an ardent croon, a melting falsetto and quick, singsong declamation".
