Bush said he'll focus his remarks on something he once heard Monroe say after listening to a player mimic his sound flawlessly: "Bill looked at him and said, 'Now that's real good. What can you play on your own?'"
Monroe, born on a farm near Rosine, Ky., was already arguably country music's greatest mandolin player when he formed his Blue Grass Boys in 1938 and began refining his sound.
"Bill Monroe was one of the greatest experimenters of them all," Skaggs said. "The whole creation of bluegrass was an experiment. It was a test-tube baby."
By the time he found Scruggs — Monroe reportedly began to dance with joy as Scruggs showed him his new three-fingered playing style — he was writing songs that would help redefine country music.
"One time he told me, 'People don't know it, but I learn from them,'" said Del McCoury, who was Monroe's lead singer for a year in 1963-64. "He meant other musicians. His music comes from a lot of different styles, jazz and what he heard as a kid."
In turn, he would influence new generations of young listeners with his sound. Doyle Lawson first heard Monroe in the late '40s on an Opry broadcast.
"I fell in love with it," Lawson said. "I asked my mother, 'Who is that?' and she told me it's Bill and he played mandolin and he sang really high. And from that day on I never took my eye off the ball. I knew I was going to play music."
