Francesca Bori has been attending Doctors Symphony concerts since she was five years old nearly 50 years ago. Her mother was the group's principal cellist, and today, Francesca fills that role. She says volunteer orchestras like this one are important.

"The preservation of music, especially of classical music, really lies with these types of orchestras, the community symphonies. It's an important part of any community to have an orchestra, to have community symphonies. It's an outlet not only for the players but for the audience," she said.

Some of these musicians have serious musical training. Francesca Bori is a music therapist and teaches at the prestigious Colburn School Conservatory of Music. Music director Ivan Shulman has credentials in two fields. The surgeon returned to the university to get a master's degree in orchestra conducting.

Others are serious and skilled amateurs, who say they come together and play because they love music.
