Farewell to Alleluia and Gloria
During the penitential seasons of the Church, the Gloria and the Alleluia are not said or sung. The Gloria is sung only at the Mass on Holy Thursday, usually with great ceremony, organ and sometimes trumpets, and often with the ringing of bells. After the singing of the Gloria, musical instruments are to be silent until the Alleluia at the Easter Vigil. (Catholic families might imitate this solemn silence by not playing instrumental music in their homes at this time.)
In the Middle Ages and throughout the 16th century, the "burying" of the Alleluia was a solemn ritual on Septuagesima Sunday. A procession of children carrying a wooden plaque bearing the word "Alleluia" laid it at the feet of the statue of the Blessed Virgin, covering it with a purple cloth. It remained there until Easter at the Gospel procession, when the plaque was carried as the priest intoned the three Alleluias before the Easter Gospel. In Paris, a straw figure inscribed with the word was carried out of the choir at the end of the service and burned in the church yard.
Although the practice of literally removing the Alleluia from the Church may have disappeared, even today in some parish celebrations of the Easter Vigil an Alleluia card is carried in procession and placed in front of the altar during the singing of the first Alleluias before the Gospel for Easter.
The hymn Alleluia, Song of Gladness and the one that follows date from the early 9th and 10th centuries; both refer to the farewell to the Alleluia in the liturgy.
