Hymnody is recognised as a central tenet of Methodism's doctrinal and liturgical identity. The church is known for its rich musical tradition, and Charles Wesley was instrumental in writing many of the popular hymns sung in Methodist congregations. "Singing the Faith" is the current hymnal, published by the church in 2011. It contains 748 hymns and songs and 42 liturgical settings (such as the Kyrie, the Sanctus and the Lord's Prayer, as well as material from the Taizé and Iona traditions). There are also 50 canticles and psalms, selected on the basis of their use within liturgy. The collection of 89 hymns by Charles Wesley is a reduction from over 200 in the 1933 "Hymn-Book".
