The Carus Choir Coach offers choir singers the unique opportunity to study and learn their own, individual choral parts within the context of the sound of of the entire choir and orchestra. For every vocal range a separate CD containing each choir part is available. The CD is based on recorded interpretations by renowned artists who have performed the work from carefully prepared Carus Urtext editions. Each choir part is presented in three different versions:

Original recording

Coach: each part is accompanied by the piano, with the original recording sounding in the background

Coach in slow mode: the tempo of the coach slows down to 70% of the original version – through this reduction passages can be learned more effectively.

The present new critical editon of the "Vesperae solennes de Confessore" KV 339, edited by Wolfgang Horn, is the first edition since the publication of the “old” Complete Edition from 1880 to be based on Mozart’s autograph score. It was thought to have been lost after the second world war but for the past several years it is again accessible through the Biblioteka Jagiellonska in Kraków. This work is now available in carus music, the choir app!
