Walter’s teaching at Bachelor level is based on his two-volume book ‘The Baroque Violin & Viola – a Fifty Lesson Course,’ published by Oxford University Press in 2020. With this book, students are able to prepare their one-to-one lessons in a detailed and informed way and at their own pace. In addition, his YouTube channel contains videos explaining and demonstrating specific technical issues that the individual student may have.
A much-travelled recitalist, Walter has recorded the Recreations of Leclair for Addes, France and Sonatas by Mondonville for Meridian, a CD that was awarded the ‘Choc’ label by the French CD magazine Diapason. In 1999 he founded Cordaria, whose highly acclaimed solo CDs on the Signum label include Vivaldi’s Violin Sonatas Op 2, the Biber Mystery Sonatas, and "Un alma inamorata," a collection of cantatas for voice, violin obbligato and continuo. In 2022 he will record Bach’s violin sonatas for the Bach Haus in Eisenach.
A Principal of The English Concert for nearly thirty years and the leader of The Orchestra of The Sixteen for ten years, Walter is now a regular visitor to The Institute for Superior Arts in Havana, Cuba, where his work as a teacher and conductor is sponsored by the Salzburg Mozarteum Trust. He has also given Master Classes in the Dartington Summer School, the Schola Cantorum in Basel, Zurich University, and the Anton Bruckner University in Linz, Austria.
As a conductor of Baroque Music on modern instruments, he has worked with the Trondheim Symphony Orchestra, The Orchestra of the Lyceum Mozartiana in Havana and the Singapore Symphony Orchestra. In 2018 he conducted Mozart’s Cosi fan Tutte in a staged production in Rotterdam.
Born in England to Viennese parents, Walter graduated from the Royal Academy of Music in London and continued his studies in Israel with Prof. Ramy Shevelov, a former Ivan Galamian assistant who later took over Galamian’s chair at The Juilliard School, and in Germany with Prof. Sandor Vegh and Prof. Michael Gaiser. Having studied towards a Master's Degree in Violin Pedagogy at the Jerusalem Academy of Music with Prof. Felix Andreiewsky (former assistant of Prof. Yankelewitch in Moscow) he completed his studies with Prof. Piotr Bondarenko, who had been David Oistrakh’s assistant.
His Baroque Violin ‘Etude’ book ‘Gradus ad Parnassum’ was published by International Music Publishers in the USA and a four-volume pedagogic ‘Baroque Violin Anthology’ for younger students is being published by Schott. He has also written a novel, ‘Healing by Deceit, The Story of Alan Palladino,’ published in 2015.
