Dennis Tobenski (born April 18, 1982 in Kankakee, Illinois) is an American composer of contemporary classical music and art song.
In 2004, he graduated from Illinois State University, where he studied Vocal Performance with baritone John M. Koch, and Music Theory & Composition with Stephen Andrew Taylor, David Feurzeig and Serra Hwang.
The ISU College of Fine Arts commissioned the 2002 Elegy, a work for choir and chamber ensemble commemorating the events of September 11, 2001, and the 2004 Soliloquy for solo flute.
Tobenski was commissioned in 2002 by baritone John M. Koch (whose 1996 performance of Il barbiere di Siviglia with the Florentine Opera was broadcast on PBS) to write Three Poems of Thomas Hardy.
He later wrote music for the 2004 Chicago production of The Living Canvas, a performance art work for theatre that combines movement and dance with photographed images projected on the unclothed human form.
