Catechesis and Chanting the Psalms

"They chant psalms, not in order to learn or pray, but for the sake of the rite, as if this work were a required act of worship, or for the sake of financial reward. Many among us celebrate the Lord’s Supper every Lord’s day after they are instructed, examined, and absolved. The children chant the Psalms in order to learn them; the people also sing in order either to learn or to pray. Among our opponents there is no catechesis of children whatever, even though the canons prescribe it. Among us, pastors and ministers of the church are required to instruct and examine the youth publicly, a custom that produces very good results." (Ap AC XV) [Click this hypertext link for an interesting article about children chanting and moral formulation.]
