Peter Watchorn (born 30 May 1957[1]) is an Australian-born harpsichordist who has combined a virtuosic keyboard technique, musical scholarship and practical experience in the construction of harpsichords copied from original instruments of the 17th and 18th centuries. As well as presenting many solo public performances and broadcasts of baroque keyboard music and participating in choral and orchestral performances, he has made numerous commercial CD recordings of solo harpsichord music from the 17th and 18th centuries.
He specialises in the music of J. S. Bach, 17th-century French and German music, and the works of the English virginalist composers. He is widely recognised as an expert on the history of the early music revival during the 20th century. His biography of the Viennese harpsichordist Isolde Ahlgrimm (1914–95) was published by Ashgate in December 2007.
