It was founded by Sarah Cline, director of the legendary jazz program at Berkeley High School in San Francisco in 2012. The events and program were meant to encourage young women to explore jazz and improvisation. A subsequent event was presented at the Jazz Education Network conference in 2017, which sparked the idea for an event in North Carolina. Since its inception, similar JazzGirls Day programs have been produced in El Paso, Boston, Seattle, Washington D.C., and Phoenix, as well as at SFJAZZ and JALC.
In March 2019, the first NC JazzGirls Day (JGD) took place on the UNC-Wilmington campus. The event brought together an all-female team of educators and performers to mentor young jazzwomen. Participation in JGD was open to all middle school and high school students who identified as young women who were interested in exploring jazz. All instruments and voices were welcome, and there was no prerequisite of jazz experience or participation in a school jazz ensemble. Twelve middle school and high school jazz girls participated in the inaugural event’s activities. In fall 2020, UNC-Greensboro director of Jazz Studies Steve Haines produced a successful JazzGirls Day event, with 38 participants and featuring saxophonist/composer Camille Thurman.
