Final answer:
In jazz performances, vocalists expanded their roles by using new vocal techniques and emotional connections with audiences. Female vocalists, acting during the Jazz Age, were pivotal in reshaping the vocalist's role by tying it to the women's liberation movement, advocating for social freedom, and challenging Victorian norms through music.
Step-by-step explanation:
Vocalists in jazz performances reflected the expansion of their role in a variety of ways, paying homage to the socio-cultural developments of the time. They did this through the incorporation of new vocal techniques that showcased both their musical prowess and their ability to connect with the audience on a personal and emotional level. Female vocalists played a pivotal role in creating this change, often using their artistic platform to push the envelope further than their male counterparts. They were critical in broadening the concept of women's liberation to include new forms of social expression, which was convergent with the women's rights movement of the 1920s.
During the Jazz Age, the individual roles of female vocalists were instrumental in reshaping the function of vocalists altogether. These roles were a reflection of the broader changes in society at the time, such as the flapper lifestyle and the push for women's suffrage. Female vocalists like Bessie Smith and Ella Fitzgerald used their music to communicate not just entertainment, but also powerful messages about gender and social norms. Their roles evolved from mere performers to influential figures in music and society, challenging Victorian era norms and advocating for new forms of social freedom.
