Tonospheres, a composition for violin and cello written by Dr. Daniel Perttu, Westminster College assistant professor of music, was performed May 12 as part of the Music@Main concert series at the Hicks Auditorium of the Jacksonville (Fla.) Public Library.

Tonospheres was performed by violinist Piotr Szewczyk and cellist Alexei Romanenko of the Jacksonville Symphony Orchestra.

The composition, completed in 2005, was premiered at the University of Arizona and performed at the Society of Composers Region V conference at Butler University in Indianapolis. The piece was selected for performance in Florida through a peer-review process of submissions from a national call.

Perttu, who joined the Westminster faculty in 2008, is the music theory program coordinator. He earned an undergraduate degree from Williams College, two masters from Kent State University, and doctorate from Ohio State University. His compositions have been performed in 20 states and China, and he was recently commissioned by the Johnstone Fund for New Music at the Columbus Foundation to compose for the Johnstone Woodwind Master Series at Ohio State University.
