The Pacific Boychoir was formed in 1998 with 6 boys, and it now includes more than 175 singers from ages 4 to 18. The New York Times said the PBA goes “beyond the reach of most youth choirs” and the Los Angeles Times described the PBA quality of sound and musicianship as “astonishing.” The chorus is divided into multiple groups: three training groups, two performing groups, and two groups for older boys whose voices have begun to change. The after school choirs rehearse up to four hours per week, and the day school choristers rehearse up to 15 hours per week.
