oratorio and cantata

Oratorio and cantata are both forms of sacred music.

Explanation: Both the oratorio and the cantata are pieces of music composed with religious purposes. In other words, they are both forms of sacred music (music connected with God and dedicated to a deity). In most cases, oratorios and cantatas are performed in churches; however, there are also secular cantatas that are not used in the liturgy of church services. Moreover, both forms of sacred music include a choir and instrumental accompaniment.
