The “Messiah” is a “monster.”
That’s how Laurie Chinn describes the legendary piece, even after serving as the organist for 17 consecutive, annual performances at a church in Portland. Every year, she said, she goes back to the drawing board for review and practice.
“There are parts that are very difficult,” Chinn said. “What I’m doing is being the whole orchestra, because it’s written for orchestra.”
English composer George Frideric Handel first scored his piece for a small orchestra (more like a big band) in 1741; the work was always warmly received, but it wasn’t until after Handel’s death that other arrangers recognized its monumental power, and reworked the score for massive groups of musicians and singers.
Other adaptations are for organ only, but they still try to squeeze in every speck of orchestral genius from those earlier passes (by the likes of arrangers like Mozart). That makes for an incredibly detailed, busy piece of music, Chinn said.
