J. S. Bach’s 200-plus cantatas hold many choral treasures. Some of the best known, such as “Jesus, Joy of Our (Man’s) Desiring” from Cantata 147, are well within the grasp of an average volunteer choir. Many of the opening choruses, on the other hand, are a challengeeven for professional singers. In Leipzig Bach was responsible for the music in several (at least four) churches, and therefore needed four choirs. Three of these were able to sing difficult music, but one could “only just barely sing a chorale” (New Bach Reader, 146).

Loosen Up: Organists need to recapture the old art of improvising
There is no better preparation for learning to improvise than to recapture a child's natural pleasure, curiosity, and interest in spontaneous music-making.

"Using an interlude to raise the pitch for the last stanza is unmusical and theatrical."
[Harold Gleason, McHiod of Organ Playing, 6th ed, 1979, p. 221]
"On special occasions, vigorous congregational singing can be promoted by transposing a hymn to a higher key for the last verse."
[George Ritchie and George Stauffer, Organ Technique, Modem and Early, 1992, p. 362]

I played my best for Him: A high purpose calls for high performance
It's time for church organists to stop apologizing for their "performance" in worship. For years people have been suspicious of the word "performance," usually reserved for more involved worship music played by well-trained organists. They Ve somehow had the idea that any music included in the service should be simple and ordinary, not complex and technically difficult.

Hymns for September, October, and November #2
Anyone who takes a close look at the history of the Christian church in the United States and Canada cannot help but be struck by the many ways in which our cultural and ethnic diversity has enriched and blessed us. We are truly a body that has been influenced by people of "every tribe, language, and nation."

Serving the Hymn: Some thoughts on hymn introductions
Jan Overduin, professor of music at Wilfred Laurier University, Waterloo, Ontario, is skilled in organ improvisation. He has performed throughout North America and is frequently heard on CBC (Canadian Broadcast Corporation) radio. He is pictured on this page at the Reil organ at Redeemer College, Ancaster, Ontario, where he accompanied three choirs in a recording of psalms entitled Sing a Psalm of Joy (available from CRC Publications for $8.95; $11.20 CDN).
