Johann Sebastian Bach was certainly familiar with the Pantaleon – a large hammered dulcimer with a wide range and full chromatic scale. Bach’s contemporary Pantaleon Hebenstreit had developed the instrument, through which he gained international renown and became one of the best-paid Dresden court musicians. The instrument enjoyed great popularity in the 18th century and was an important precursor of the fortepiano, its younger brother.

Whilst we cannot know if they had met in reality, our imagination has nonetheless been much exercised. What would Bach have put on his famous colleague's music stand?
