Piano/Organ by Boehm, J

This is one of the few surviving hammer-action grand pianos equipped with an organ stop. The overblowing flute register lends an enchanting quality to the instrument's sound. Combined with the instrument's other tonal modifications—such as the Janissary stop, bassoon stop, moderator, and damper lift—these features offered the musician a sonic palette capable of adding unique dimensions to performances, particularly of variations or musical tone paintings. Additionally, there are pedals for operating the bellows system and for playing the organ register either independently or in combination with the piano.
