A behind-the-scenes look at the LDS Church’s most iconic instrument and the man who keeps it in tune

It has been a symbol in The Church of Jesus Christ of Latter-day Saints for more than 160 years. You see it on television and hear it on the radio every week. You find it whenever you reach for the faith’s hymnal. For decades, it loomed as the most prominent fixture at General Conference. But to Joseph Nielsen, the Salt Lake Tabernacle’s famed pipe organ is more than a musical companion to a celebrated choir’s weekly performances, more than an embossed image on a songbook, more than a majestic monument to the pioneer past, more than an emblem of a global religion. To Nielsen, it’s personal. Video by Trevor Christensen of The Salt Lake Tribune.
