Featured composers include Leo Weiner, Anton Arensky, Maurice Gardner and John Wiliams.
Presenting concerts every Wednesday through August 18, the festival is supported by contributions by individuals and businesses, including Chief's Restaurant.
An unsual work on the program will be the quartet for violin, viola and two cellos by the Russian romantic composer Anton Arensky, who wrote it in memory of his teacher Tchaikovsky.
"I've never heard this piece before," said DePauw music professor Eric Edberg, the artistic director of the festival. "I've heard it's an extraordinary work -- and with two cellos in it, how could it not be?"
Edberg laughed and added, "That may be my cellist's bias. In any event, Margot Marlatt and Margie Hanna, the daughter-in-law of DePauw's late band director Professor Dan Hanna, are two of my favorite Indiana cellists, and I'm looking forward to hearing them very much."
John Williams is known for his award-winning film scores for movies such as "Jaws" and the Indiana Jones series. Not everyone knows he is also an important composer of classical concert music. His Duo Concertante for Violin and Viola was written in 2007 for members of the Boston Symphony Orchestra, an organization with which Williams has had a long relationship since his many years as Director of the BSO's Boston Pops series.
The Festival continues next week with a recital by Ball State University flute professor Mihoko Watanabe and pianist Nariaki Sugiura.
