Diana Boyle was born in London and educated at St. Paul's Girls' School and as a Foundation Scholar at the Royal College of Music. In 1970 she continued her studies under Enrique Barenboim in Tel Aviv, and in 1973 was awarded a Fulbright Scholarship to study with Artur Balsam in New York. Balsam's profound musical insight into the classical and chamber music repertoire, together with his friendship and encouragement until his death in 1994, proved to be the pivotal influence on Diana's own musical life.
After making her London recital debut in 1979 she gave concerts in the USA, Canada,Spain, Portugal and England. She also taught piano and chamber music in London and in the USA. In 1987, Diana was invited to make a series of recordings for National Public Radio in Boston. This included performances of the Bach Partitas, the late Schubert Sonatas, and Beethoven's Diabelli Variations (this recording was subsequently released on CD by Centaur Records USA in 1989). In 1990 Diana returned to the Bach Partitas, recording this time at Forde Abbey in Dorset, England (for Integra Records). She then turned to the late Brahms piano works, Op 76 and Op 116-119.(Integra 1994), Bach's Well Tempered Clavier Book 2 followed in 2000 (Metier MSV2002), Bach Goldberg Variations in 2003(Elective Solitude Recordings) and now a recording of Bach Art of Fugue - all taking place at Forde Abbey. All of the above recordings are now on Divine Art and Metier Records.
Her love of the entire recording process, with its sense of solitude – the music made in privacy and surrounded by silence – followed by taking responsibility for all the editing decisions(with the meticulous technical support and loyalty of Brad Michel, her sound engineer) has enabled her to explore these extraordinary musical masterpieces in depth during the last twenty years.
In 2001, Diana moved from London to Southern Portugal.
