Cantor

A singer who sets the pitch and leads the liturgical singing of psalms, canticles, anthems, and other sung texts. Cantors often lead unaccompanied singing. In responsorial recitation of the Psalter, the cantor sings the verses of the psalm and the congregation sings a refrain after each verse or group of verses. This was the traditional way of singing the Venite in the Daily Office, and it was also a traditional way of chanting the psalms between the lessons at the Holy Eucharist (BCP, p. 582).
