A vocal ensemble is a group of singers who perform together, often without instrumental accompaniment. These groups can vary in size, ranging from small quartets to larger choirs, and they typically focus on harmonizing and blending their voices to create a rich sound. Vocal ensembles can perform a wide range of music styles, including classical, jazz, pop, and folk. Members of a vocal ensemble often rehearse regularly to develop their vocal techniques and improve their ability to sing in harmony. They may perform at various events, such as concerts, competitions, and community gatherings. Notable examples of vocal ensembles include The King's Singers and Pentatonix.
