Den Herder has been a dedicated teacher ever since he took a professorship at the age of 22 at the Utrecht conservatory. His lessons are based on the development between mind and body, and a cello technique inspired by his teacher Christopher Bunting, a former student of Pablo Casals. Cello playing based on natural principles like gravity, character and playfulness.

“Everything is music, play not to avoid mistakes, delegation of body functions and breathing” are some key topics which will lead to a healthy way achieving perfection. His main focus is making people aware what they exactly practise. He believes being aware of one’s imagination, sensitive listening, intuition and delegation of body functions are elements that have proved to be the best teachers for life.

He’s been a regular guest teacher at the Conservatory in Minsk (2003-2010) and visiting guest- professor at the University in Tainan, Taiwan. Furthermore he has given masterclasses in Holland, Belgium, Spain, Germany, France, China and Israel. Today he helds positions as a teacher at the Conservatories of Utrecht and Rotterdam.

“I’ve heard Jeroen den Herder performing the Elgar cello concerto with the Sint Petersburg Philharmonic Orchestra. He played with great distinction and sensitivity, and I believe he will grow into a wonderful cellist” Yehudi Menuhin, 1995.

Arnold Marinissen: ‘For me, creating music is all about immersing. Warmth and pulse are words that come to mind when I try to describe my music. Voice and text are important; I like to follow the route that a text lays out for me, to deal with breath, diction, nuances of intonation, and I’m intrigued by the personality of each individual voice.’
