Bandleaders are individuals who direct and manage a musical group, known as a band. They are responsible for guiding the musicians, making decisions about the music selection, and often leading rehearsals and performances. Bandleaders play a crucial role in shaping the band's sound and style, ensuring that all members work together harmoniously. In many cases, bandleaders are also musicians themselves, playing instruments or singing alongside their group.
