Keitaro Harada's days are filled with music. Hours and hours of it, day in and day out from week to week.

And that's just fine with him because Harada is one of two graduate students in the recently established James E. Rogers Institute for Orchestral and Opera Conducting at the University of Arizona.

Not only does he study conducting with the UA's Thomas Cockrell, but he also works with the Arizona Opera, Tucson Symphony, Arizona Symphony (which Cockrell conducts) and University Philharmonic orchestras. In addition, he is conducting the Arizona Repertory Theatre's spring production of "Music Man."

He's so busy with rehearsals and performances that "sleeping in" is a luxury he rarely enjoys.

"It's incredible," Harada said of the schedules he and fellow graduate student conductor Jackson Warren keep. "I can't say it's easy," he said, "but you've got to do it while you're young."

Harada and Warren will be featured conductors this weekend in the 36th annual President's Concert by the Arizona Symphony Orchestra.

The concert is always an anticipated event in Tucson because it features the best of the UA School of Music's students: the four winners of the school's annual Music Concerto Competition.

Concert times are 7:30 p.m. Saturday and 3 p.m. Sunday at Crowder Hall on the southeast corner of North Park Avenue and East Speedway.

The competition winners, representing the string, wind/brass/percussion, vocal and keyboard areas of study in the School of Music, will present solo performances with the Arizona Symphony Orchestra.

The soloists are Amber Reed, viola; Rouzbeh Tebyanian, piano; Seth Kershisnik, bass baritone; and Tori Hauk, flute.

Tickets are $9 general admission, $7 UA employees and seniors, and $5 students.
