The son of Johann Sebastian Bach (1685–1750), Carl Philipp Emanuel, described his father’s Sonatas BWV 1014–1019 as among the best works his father ever wrote and continued to perform them extensively after his father’s death. This is music of implication and inference, the emotions no less real for their apparent lack of specificity. There is pleasure in the paradox: even without a text, the music sings.

Thomas Bystrom (*Helsinki 28.8.1772, ♱Stockholm 2.10.1839) was an officer, amateur composer and musician of Finnish descent who spent his life working in Sweden. His history and musical pursuits are to some extent obscured by the same veil of mystery as the secret societies typical of the times. Many of the questions surrounding his musical studies and activities remain unanswered. Yet he would appear to have been a man of considerable musical stature by contemporary Nordic standards. The compositions by him preserved for posterity are proof of his talent.

All but the last of Johann Sebastian Bach’s six sonatas for violin and harpsichord (BWV 1014–19) commence with slow movements of intense feeling. This is music of implication and inference, the emotions no less real for their apparent lack of specificity. There is pleasure in the paradox: even without a text, the music sings. The copying and the performance of these sonatas were crucial to the mission of memorialising Bach’s music, but not merely as a matter of historical interest or archival fastidiousness. C. P. E. Bach described these works as among the best works of his 'dear departed father': they still sound very good and give me much joy, although they date back more than fifty years. They contain some Adagios that could not be written in a more singable manner today.' C. P. E. Bach’s well-worn copy of the Sonatas shows that he played them frequently. In this recording, Tuija Hakkila plays a copy of a Gottfried Silbermann 1747 fortepiano by Andrea Restelli. J. S. Bach played one of his fortepianos in 1747 in Potsdam for Frederick the Great and his court musicians. In his last years Bach even seems to have served as a dealer for Silbermann’s fortepianos in Leipzig.

Since the earliest recordings of Biber’s Rosenkranz or Mystery Sonatas made during the 1960s, there has been ever-growing interest in these beautiful pieces and a wealth of recordings. In the dedication to his patron, Max Gandolph, Prince-Archbishop of Salzburg, Biber explained that the subject of each Sonata is a section from the Catholic devotion known as the Rosary. He arranged the 15 Sonatas, scored for violin and continuo, into equal groups of Joyful, Sorrowful and Glorious Mysteries, and concluded the cycle with an unaccompanied Passacaglia which provokes a meditative coda to the 15 central events in Christian history. This piece and the opening sonata of the set are alone in not requiring scordatura – that is, retuning of the violin strings which enables composers to achieve unconventional sounds as well as facilitating some fingerings.
