On October 30, the Canyon Heights Academy (CHA) Cardinal Choir performed our National Anthem a cappella at Maples Pavilion on the campus of Stanford University. CHA wowed the audience singing a cappella before the start of the Stanford University Women’s Volleyball game against opponent Arizona. More than 200 Canyon Heights students, parents, faculty and staff, dressed in uniform and CHA spirit wear attended the game. Judaline Swinkels, director of the Cardinal Choir, rehearsed the song for weeks before the performance because it is a very difficult song to perform. The range of notes is very wide, containing notes that are both very high and very low. After the National Anthem, the CHA Cardinal volleyball teams lined up to make the fan tunnel when the Stanford starter players were introduced.
