Vocalmente Academy & VocalMentor

Katarina Henryson

Singing has been her chosen means of expression ever since her early schooling at Adolf Fredrik´s Music school in Stockholm, Sweden. Although she took a glance at the piano and the cello, singing remained the main focus through her training at the Stockholm Royal Academy of Music. During the 1990´s she was active as studio and backing vocalist in the fields of pop and soul.

Since 1984, as one of the founding members of The Real Group, Katarina has contributed to the group with her flexible altovoice and distinctive stage presence as well as with numerous compositions.

Together with The Real Group she has performed thousands of concerts all over the world and her voice can be heard on more than 20 of the group´s cd´s.

As a workshop-leader with models for choirs and vocal ensembles her experience is as vast as the artistic career.

Since leaving the group in 2016 her energy is divided between the continuing career as a singer as well as towards developing The Real Group Academy. She has recorded a Duo cd ”High Low Or in Between”  together with  cellist and composer Svante Henryson released on BIS/Naxos.

Since 2017 she has been collaborating with performance artist Lynsey Peisinger whom she met in the role of being the vocal coordinator on a Performance piece called the Cleaner by Marina Abramovic. As a duo they present workshops and performance works called Sonic and Energetic spaces that involve choirs.

Katarina has always been drawn to the jazzy side of music and nourished an interest in improvisation. Since 2013 together with members of Rajaton, Vox North and Zap Mama Katarina is part of the A Cappella improvisation group Songs of The Moment.

The directness of the human voice has always been in the centre of Katarina´s interest. With Songs of The Moment and in a workshopformat she calls Voicefulness she is creating a platform for this to evolve even more.
