In Christian music, a Passion is a setting of the Passion of Christ. Liturgically, most Passions were intended to be performed as part of church services in the Holy Week.
Passion settings developed from medieval intoned readings of the Gospel texts relating Christ's Passion, to which later polyphonic settings were added. Passion Plays, another tradition that originated in the Middle Ages, could be provided with music such as hymns, contributing to Passion as a genre in music.
