This is the feed from Chris Rowbury's blog: weekly musings from a Natural Voice Practitioner about choirs and singing.
Chris Rowbury is a choir and singing workshop leader based in the UK. He teaches unaccompanied harmony songs from across the globe, all in the original languages. As a Natural Voice Practitioner, Chris believes "that singing is everyone’s birthright and he is committed to teaching styles that are accepting and inclusive of all, regardless of musical experience and ability”.
