DURBAN, SOUTH AFRICA — In a sunny room at the Durban Music School, an 18-year-old trumpet player shot her hand in the air.
"I have a question about your embouchure," said Palesa Ndlela, referring to the way trumpeters position their lips on the mouthpiece. "Because I've been told I need to improve mine."
"I'll tell you what," said Manny Laureano, the Minnesota Orchestra's principal trumpet. "We're both going to close our eyes."
He and fellow trumpeter Robert Dorer shut their eyes and listened. Ndlela played an arpeggio. "Louder," Laureano instructed, his eyes closed. She played again, louder this time. "Now sit up from your chair like you're standing." She played once more. "Take a much bigger breath."
This time, her tone was brighter and fuller and fine. Her eyes got wide. She and the rest of the students burst into happy laughter. Laureano laughed with them.
"OK, we just fixed your embouchure," he said.
Laureano was among a dozen Minnesota Orchestra musicians coaching small groups of student instrumentalists Sunday before the orchestra's concert that night in Durban's grand City Hall, one of five stops on its South African tour.
These intimate daytime gigs — at music and elementary schools, with 10-year-old newbies and seasoned youth orchestras — might be as important as the ticketed performances on this tour. Often, the audiences that pack the rooms, classrooms and courtyards are black and mixed-race, in neighborhoods far from the city center or concert hall.
