John Katsilometes of the Las Vegas Review-Journal highlighted Gaga's vocal skills, saying she was "nailing several a cappella moments" during her jazz performances. Writing for Paper Mag, Michael Love Michael also complimented her voice, finding it "full of brightness, nuance, and emotion", while noting that Gaga's performance "brought up instant feelings of nostalgia that continued throughout the show". For Nick Remsen at Vogue, "Jazz & Piano is entertaining, engaging, educational (thanks in part to black and white filmic interludes...), and astutely conceived for power and provocation without being overbearing. Plus, it wholly demonstrates the extraordinary performing prowess and big heart [...] of its star."
