Schloeder, Steven J. (1998). Architecture in Communion: Implementing the Second Vatican Council Through Liturgy and Architecture. Ignatius Press. p. 137. ISBN 9780898706314. In monasteries, when the choir o[r] schola cantorum was composed of religious, it was usually within the cancelli in front of the sanctuary. The liturgical movement of the Baroque age removed it to a choir loft at the back of the church, thus enabling the sanctuary to be more integrated with the nave.
No loft - music has to have microphones to project
