"I wouldn't say [he was] yelling, but exclaiming forcefully," his son David Lillehaug said, laughing. "You'd hear the student's tone and pitch improve."

Leland Lillehaug, a musician and educator who spent 35 years steering Augustana University's music program, died July 9 after a series of stroke-like events. He was 91.
Lillehaug was born in South Dakota on Feb. 11, 1927. The youngest of three, he lived on the family farm near the small town of Lane and graduated valedictorian of his seven-member high school class.
