Resounding Harmony at a 2010 performance.

Resounding Harmony begins its fourth season of musical philanthropy on Sunday with its first rehearsal. And auditions for new members are set for Monday.

The group said the audition process is quick and painless. Bring a prepared piece to sing. This can be anything out of a hymnal, an opera or a Broadway show. An accompanist will be provided, so bring a copy of the music. The audition takes about five minutes and beyond the prepared music you might be asked to sing scales to determine your vocal placement in the chorus.

Resounding Harmony raises money for other organizations at each of its concerts. This season, Our Heartfelt Season, will benefit two North Texas organizations.

The fall concert on Nov. 22 will benefit the Make-A-Wish® Foundation, and the spring concert on June 19 will benefit the American Heart Association. Past beneficiaries include the North Texas Food Bank, the Fine Arts Chamber Players program to provide violins to underserved schools in DISD, the Susan G. Komen Foundation and the Palliative Care Unit of Children’s Medical Center Dallas.

Rehearsals take place at Oak Lawn United Methodist Church at 3014 Oak Lawn Ave .
