Vienna Choir provides a 25 GB vocal collection, offering the full range of the human voice with soprano, alto, tenor and bass ensembles.

This project was among the most physically demanding of all of the Vienna Instruments, where the challenges of achieving perfect tone, intonation, consistency, and stamina were directly linked to, and even magnified by, the mechanics of the human body. Given the rigorous criteria for inclusion, the voices of Vienna Choir were cast and assembled exclusively for the recording sessions at the Silent Stage, with each singer hand-selected from Austria's leading choirs.
