Music classes teach an appreciation of music and develop the vocal capability of each child. Music theory is taught at an age-appropriate level. The students get to perform at various assemblies during the school year. In the Upper School, girls may audition for membership in the Tartantones , an a capella group that performs at events at Stuart and in the wider world. Beginning in third grade, drama classes encourage the girls' creative expression while helping to develop concentration, poise, teamwork, and self-confidence.
Students also get to try their hands at improvisation and writing plays.
In conjunction with the music and drama departments, the fifth and eighth grades each stage a musical production. In the Upper School, one dramatic production and one musical are presented each year.
