The intelligent preacher will study his congregation and its capacities of song to determine what he can do. He will canvass their responsiveness to certain classes of hymns, solemn, cheerful, aggressive, meditative, emotional, didactic—literary, popular. Their taste in the tunes to be used will need to be carefully considered. It would be folly to announce “When the Roll is Called up Yonder” in a congregation used to singing and enjoying Luther’s “Ein’ feste Burg ist unser Gott”; equally so to ask a congregation that enjoys singing “There’s sunshine in my soul” to sing Iron’s version of the “Dies Irae.” A survey must needs be made of the musical resources and of the adaptability of musical helpers. In some cases such adaptability needs to be trained and developed. Their pliancy in rapidly taking up new methods, and executing unexpected plans of the preacher quickly, will require training. _Studying Methods of Announcement and Securing Participation._ An important study will be how to announce and introduce the hymns in such a way as to awaken the interest and to win the sympathetic attention of the members of the congregation, and also how to help the people to sing with their minds and hearts, as well as with their vocal cords. The methods to be used in securing full participation in the singing, without losing sight of the deeper meaning of the hymn, will need to be formulated or borrowed from successful leaders of song. The problem is not met by merely urgent demands that everybody sing; they must all be moved upon to want to sing. Can it be done by illustrations, by moving anecdotes, by tender appeals bearing on the thought and feeling of the hymn in hand? The kind of anecdotes and how they are to be used, before or during any given hymn, will call for careful discrimination. How shall the preacher acquire the power of introducing a hymn in a very few well-chosen words, vibrant with the feeling the hymn expresses, striking the spiritual key connecting up the hymn with the religious purpose of the whole service? Year after year, by observation of other ministers and song leaders, by his reading, by experiments of his own, he will acquire a body of efficient methods with which to vitalize his song service. _Studying Use of Hymnal for Specific Purposes._
