"O for a Thousand Tongues to Sing" is one of Charles Wesley's most famous hymns, written in 1739 to mark the first anniversary of his conversion to Christianity. The hymn was inspired by a remark made by Peter Böhler, a Moravian missionary, who said, "Had I a thousand tongues, I would praise Him with them all." The music is commonly set to various tunes, including one by Thomas Jarman, a English composer known for his hymn tunes in the early 19th century.
