Haydn composed his solo keyboard sonatas between c. 1750 and 1795, during the period in which the piano was gradually taking the place of the harpsichord. The early sonatas are mostly short, light, and ‘easy’, tailored for amateur musicians and students. After 1765 Haydn composed several sonatas the scope and depth of which are completely new. Over a six- or seven-year period Haydn produced a sequence of ambitious sonatas of a difficulty that resulted in their being poorly circulated. In this latest volume of Haydn’s piano sonatas, Jean-Efflam Bavouzet again chooses a range of sonatas, planned to provide a balanced programme characterised by different moods and temperaments. He explains: ‘This is a long-term endeavour, in which, as the years go by, each album will be like a postcard sent from my journey. Although this journey does not greatly respect chronological considerations, it is being undertaken with the greatest passion so as to try and bring the limitless treasures of this sublime music to life as vividly as possible in our twenty-first-century ears.’ The previous volumes have elicited such comments as ‘A recording worth rushing to the shops for. Bavouzet plays these inventive masterpieces with real love’ (Classic FM on Volume 3) and ‘This series is turning into a real classic: Jean-Efflam Bavouzet has an infectious sense of witty fun that underlies so many of Haydn’s inventions’ (The Observer on Volume 4).
