My little parish group of 12 is learning from the "Let's sing with the Pope" videos from PIMS and like them. In rehearsals I simply sing the phrases they need help with and repeat until secure. They have the Kyrie VIII, nearly the Agnus Dei VIII and look forward to starting Sanctus VIII. All but one are women so I am wondering would it be better to let them hear recordings by women's choir? So far I found
