In many churches, the Sunday before Easter serves as a celebration of Jesus' triumphal entry into the city of Jerusalem, in which the Bible records that local waved palm branches in his honor.
Known as Palm Sunday, the day begins what is called Holy Week, a time on the liturgical calendar that includes Holy Thursday, which recalls the Last Supper, Good Friday, which recalls the Crucifixion, Holy Saturday, and finally Easter.
The observance will often involve members of a congregation taking palm branches and waving them during worship, especially the opening processional of the service.
Here are seven songs that are used to celebrate and contemplate the significance of Palm Sunday. They include works ranging from Medieval times to this very century.
