The tradition of the second chorus in jazz, influenced by African music, emphasizes variation and it originated in early New Orleans parades and evolved through big bands, into more intimate vocal jazz settings. This practice is a crucial element in vocal jazz that allows singers to explore and experiment with their vocal delivery, to showcase their interpretative and variational skills. A case study analyzing the interpretative approaches of legendary singer Sarah Vaughan is included in this article. Selected recorded tracks from Vaughan’s album Live at Mister Kelly’s, were transcribed and analyzed, comparing them with the original published lead sheets. The musical analysis focuses on Vaughan’s interpretation of the melody and the variations she employs during the second chorus. Her mastery of this practice, through innovative rhythmic and melodic variations, interplay with the band, and expressive use of lyrics, enhances the musical narrative and captivates the audience. The main research question is: “What musical gestures and tools does Sarah Vaughan use in her recapitulation of the melody in the second chorus of jazz songs?”
