To solve these problems, someone was needed to take on the role of conductor. The conductor would be responsible for setting the tempo, dynamics, and other musical aspects of the performance. This would ensure that all musicians were playing together in a cohesive manner.
In addition to their musical responsibilities, conductors also had other roles. For example, they would often act as the musical director of a group, choosing the pieces to be performed and rehearsing the musicians. They would also serve as the artistic director, overseeing the overall artistic vision of the group.
Today, conductors still play an important role in musical performance, although their duties have changed somewhat. They no longer need to worry about setting the tempo or dynamics, as these can be controlled electronically. However, they still play a crucial role in leading and inspiring the musicians and in creating a cohesive performance.
In addition to their musical duties, conductors also have other responsibilities. They often serve as the music director of an orchestra, choosing the pieces to be performed and rehearsing the musicians. They may also give lectures on music or lead master classes for young musicians.
