Very little is known about the origin of J. S. Bach’s seven Toccatas (BWV 910–916) or of their use. They are believed to have been written before 1717 or the end of Bach’s Weimar period – but it is quite possible that at least some of them were drafted before he arrived there in 1707, at the age of 22. The Toccatas are usuallyperformed on harpsichord or piano – but even though they are ‘manualiter’ (intended to be played by the hands only) and do not call for pedal parts, they are also occasionally heard on the organ. In terms of style they are examples of the so-called stylus phantasticus – ‘the most free and unfettered method of composition’ – and belong to the North German organ tradition of the late 17th century.
