Grand piano

The keyboard compass is 85 notes, AAA-a4. The instrument is straight strung with individual hitchpin loops on an iron frame composed of separate elements bolted together. The stringing comprises eight overspun unichord courses , three overspun bichord courses, six overspun trichord courses, and 68 simple trichord courses. The instrument has an English check action with underdampers to b2. The dampers are strongly graduated in size from bass to treble. The two wooden pedals operate the una chorda (left) and sustaining (right) devices. The oak case was originally stained green (now faded) and is decorated with birds, fruits and flowers executed in relief in silvered and gilt gesso.
