At 86, Saburo Takata may be the oldest working composer of classical music in the world. Not that he feels like it.

"I have never felt like I am getting older," he said. "Every day holds some new discovery. I enjoy myself constantly."

He devotes several hours a day to composing new works or improving old pieces. In May, Takata released an elaborate compilation, "Liturgical Hymns for Mixed Voices," which includes "Ave Maria," "St. Francis' Prayer for Peace" and more than 100 psalms.
