Guillermo Rozenthuler

I’m a voice coach and vocalist based in London. My passion is to inspire individuals and groups to discover and enjoy their voices fully and truly.

Born in Buenos Aires, Argentina, Guillermo ( is a versatile vocalist and a skilled voice teacher and group facilitator.

He enjoys inspiring individuals and groups of people to listen, breathe freely, sing the sound of their essential nature and be fully present, honest and open. He believes singing is everyone’s birthright beyond musicianship or vocal skills, as it was for millennia in human evolution.

Besides his performing career as a soloist and his participation in bands such as Tango Siempre and Rioplatenses singing Argentine tango and folklore, Guillermo devotes his energy to teaching. His work as a vocal coach and workshop leader involves weekly harmony singing workshops and one-to one lessons from his London studio, and regular seminars and master classes throughout Europe, mainly as a faculty member of the Global Music Foundation. He’s currently leading various community singing workshops organised by Live Music Now,The Singing Well for Harrow Community Centre and Choir With No Name.

The one-to one lessons and collective singing workshops he facilitates combine harmony songs from all over the world with gentle movement, stretches and sensory awareness (informed by Yoga, Feldenkrais method and other disciplines). He also encourages ‘sounding’ (producing vocal sounds that are not necessarily ‘singing’) and sometimes incorporates singing exercises and vocal explorations (drawing from functional pedagogy of the voice, speech-level voicework, anthropological singing, classical vocal technique). Rhythm, silence and improvisation are also present in most of the sessions, as well as from the indispensable sense of humour!

Guillermo moved to the UK in 2000 after more than 10 years teaching in Buenos Aires, where he helped shape a generation of popular singers. His vocal formation in Argentina included classical singing with Julio Raggio, Anthropological Singing (Canto Esencial) with Iris Guinazu and Functional Pedagogy of the Voice with Renata Parussel. He developed performing skills with Daniel Suarez Marzal, Alejandro Cancela and Adrian Porcel. He has taken part in numerous Tai chi Chuan, Yoga and Awareness through Movement seminars.

In the UK he has studied Indian Vocals with Doctor P Chaudhry and the renowned vocalist Ajoy Chakraborty, and in India with Rajesh Kelkar. In 2007 he achieved a Masters degree with distinction in Ethnomusicology (Middle Eastern music, Arabic singing with master Abdul Salam Kheir) at SOAS.

His work is largely informed by his yoga practice, inspired by yoga teacher and change-maker Judith Seelig. He’s also been a disciple of Bobby Mc Ferrin and Rhiannon, two of the world’s greatest vocal improvisers and group singing facilitators.
