The Time is a very primary consideration, but it is too often treated as a matter of no consequence. Large bodies move slowly, and hence the tendency to drawl out tunes in numerous assemblies. We have heard the notes prolonged till the music has been literally swamped, drenched, drowned in long sweeps and waves of monotonous sound. On the other hand, we cannot endure to hear psalms and solemn hymns treated as jigs, and dashed through at a gallop. Solemnity often calls for long-drawn harmony, and joy as frequently demands leaping notes of bounding delight. Be wise enough to strike the fitting pace each time, and by your vigorous leadership inspire the congregation to follow en masse. May we in the very gentlest whisper beg you to think very much of God, much of the singing, and extremely little of yourself. The best sermon is that in which the theme absorbs the preacher and hearers, and leaves no one either time or desire to think about the speaker; so in the best congregational singing, the leader is forgotten because he is too successful in his leadership to be noticed as a solitary person. The head leads the body, but it is not parted from it, nor is it spoken of separately; the best leadership stands in the same position. If your voice becomes too noticeable, rest assured that you are but a beginner in your art.
—Charles Spurgeon, The Sword and The Trowel, June 1, 1870. 276-277
