Like many musicians, Tim Posner was born into a musical environment. His father is was a violist, and his mother, a cellist, "quite naturally" became his first teacher. Apart from a passing desire to embark on a career as an opera singer - which even led him to play the shepherd boy in Tosca at the Royal Opera House, Covent Garden! - the prospect of a life dedicated to the cello became clear from the age of thirteen, fuelled in particular by his early discovery of the infinite field of chamber music. After studying at the Junior Department of the Royal Academy of Music, Tim Posner crossed the Channel at eighteen to join Leonid Gorokhov's (winner of the First Prize at the Geneva competition in 1986) prestigious class at the Hochschule fur Musik in Hanover at the age of eighteen. In addition, he regularly benefits from Steven Isserlis' wisdom during masterclasses, which proved to be a decisive source of inspiration. He has since enjoyed a flourishing career, dividing his time between engagements as a soloist and chamber musician. In 2010, he founded the Teyber Trio with Tim Crawford and Timothy Ridout, with whom he is still active. He has also recently been appointed principal cello of Amsterdam Sinfonietta.
