Jennifer Margaret Barker's compositions have been hailed by critics as "at once gripping and timeless", "beautiful...warm", "haunting", "toe-tapping", and her compositional output has been noted for its "amazing array." As conductor Mark U. Reimer states in her 'Nyvaigs' CD liner notes, "...Barker is a musical pilgrim on a completely original path. In her music, one hears the passion and strength of her Celtic heritage, yet the colors are fresh and her style engaging."

Barker has received commissions and performances from most notably The New Jersey Symphony Orchestra with the New Jersey Youth Chorus, The Virginia Symphony with The Virginia Children's Chorus, Network for New Music, The Society for New Music, Trio Arundel, The Bearsden Choir with the BBC Scottish Symphony Orchestra Brass and Percussion Ensembles, The Scottish Chamber Orchestra String Quartet, The Scottish Chamber Orchestra String Trio, The Holywell Ensemble, Marimolin, The Children's Chorus of Maryland, and The Bay Youth Symphony, as well as numerous international concert artists. She was also invited to compose a work for The American Liszt Society. Her compositions have been performed in continents as far apart as Asia, Australasia, Europe and North America.

Published by Theodore Presser, Vanderbeek & Imrie Ltd. and Southern Percussion, Barker has received a wide variety of awards, and multiple broadcasts of her compositions on American public radio and the BBC. Her first CD, 'Nyvaigs', was released in April 2000 on the CRI label. Her second CD, 'Geenyoch', which includes a bonus DVD featuring four music videos of her compositions filmed by award-winning cameraman John Anthony Palmer, was released in May 2005 on the Meyer Media LLC label (www.meyer-media.com).
