Specializing in a cappella music of the Renaissance and the 20th and 21st centuries, the Ars Nova Singers of Boulder, Colorado are presenting their 25th concert season in 2010-2011. The professional-core vocal ensemble conducted by founding Artistic Director Thomas Edward Morgan is composed of 36 selectively auditioned choral musicians from the Denver/Boulder metropolitan region. In its history, the Ars Nova Singers has presented over 250 performances of more than 100 different concert programs.

The ensemble has received significant national recognition - the Aaron Copland Fund for Music selected the Ars Nova Singers for funding in 2003 and 2004 .The Performing Ensembles program of the Copland Fund supports organizations whose performances encourage and improve public knowledge and appreciation of serious contemporary American music. The ensemble has also been funded by the Chorus Program of National Endowment for the Arts.

The musical accomplishments of the ensemble range from performances of the complete Responsoria by the eccentric late Renaissance composer Carlo Gesualdo to the premiere of new works by many Colorado and other American composers. In September, 2002 the ensemble premiered a major new work, I Heard a Voice, composed by Thomas Edward Morgan and New York visual artist Lesley Dill. The project has subsequently been presented internationally: in June of 2003, the Ars Nova Singers performed the piece at the Evergreen Cultural Centre in Coquitlam, British Columbia.

The choir has participated in numerous commissioning and new music projects, performing new works by Libby Larsen, Stephen Paulus, Luis Jorge Gonzalez, Jan Gilbert, R. Anthony Lee, and Terry Schlenker. The ensemble has recently joined in a consortium commission of the 2005 Pulitzer Prize-winning composer Steven Stucky.

The Ars Nova Singers have been heard in radio broadcasts throughout the United States, Canada, South America, Australia, Japan, and Europe, including such National Public Radio programs as The First Art, Music from the Hearts of Space, and locally on Colorado Spotlight and Colorado Matters.

Ars Nova has released ten independent recordings on compact disc, and performed on seven internationally released recordings with Boulder composer and instrumentalist Bill Douglas.
