The vocalists of Ars Nova Singers are an adventurous, highly skilled cadre drawn from all over the Denver Metro Area. By retaining upwards of 40 auditioned singers, we’re able to conquer the toughest polyphonic terrain with ease. 8 parts? 16 parts? No problem. (Over the years, we’ve even dared to perform a few 40-part tunes – just for the fun of it.) We believe in strength in numbers, and we’re grateful to our singers for performing the kind of complex works that few other choirs attempt.
