She also works as a lecturer, writes for professional magazines, and brings years of stage experience plus a degree in Popular Music (major in voice) into this app. Her unique teaching concept combines practical training, body awareness, and musicality. What Judith’s students say: “Judith Erb is an excellent coach and very personable. With her guidance, even untrained voices can quickly achieve success without losing their individuality. I’ve attended several of her workshops and each one was worth it!” – Bettina, Hungen “Judith explained the vocal system with its three areas – breathing, opening, and relaxation – very clearly and motivating, both theoretically and practically. Her many examples made everything easy to understand. Her way of working with us was human and appreciative. For me as an experienced choir director, this was the best vocal training I’ve ever attended. Even after 35 years of experience, I gained more clarity and confidence for my voice and choir work. Thank you!” – Brigitte, Fulda “I’ve been singing in a choir, a quartet, and a band for many years, and I also take singing lessons. Just one day with Judith gave me powerful and intensive impulses that made high notes much easier. Watching the progress of all participants within a single day was impressive. Thank you for that wonderful day – the 90-mile trip was absolutely worth it.” – Heidi, Mainz “Judith’s workshop was very instructive and inspiring. Thanks for all the great tips and ideas, and for the pleasant and enjoyable day.” – Hansi, Mainz “I’m impressed how you help people break through their vocal barriers – a great workshop today.” – Martin, Petersberg “I have tried many kinds of vocal training before. Her instructions are really effective for self-practice. No one has ever explained breath support so clearly. I now practice regularly with her methods and singing has become easier, better, less tiring, and my voice lasts longer without strain. Thank you – keep it up!” – D.H.
