What function does a cantor serve in addition to assisting a rabbi?

A cantor, also known as a hazzan, plays a vital role in Jewish worship, primarily by leading prayers during services. This individual is often responsible for chanting the liturgical texts and melodies, guiding the congregation in prayer, and enhancing the spiritual atmosphere of the service. The cantor's expertise in music and liturgy allows them to engage the community, making moments of worship more meaningful and accessible.

While the cantor may indeed take part in organizing community events, teaching religious classes, or performing weddings, their distinct primary function within the religious framework is to lead prayers, especially during traditional services. This leading role is central to the communal prayer experience and supports the rabbi in fostering a rich spiritual environment for congregants.
