Cristofori's Piano Keyboard

Origin
Bartolomeo Cristofori was originator of the modern piano. Cristofori was well regarded among the nobility for his skill at building instruments, but his newly tuned piano received little interest. The in-vogue harpsichord was transformed in to hammer based instrument. Changing the force tickling the ivories allowed a musician to control each note’s loudness, introducing new dimensions to the orchestra. Many of the advancements he originally proposed to get the finest sound were only reintroduced centuries later when production costs dropped. Three examples of his pianos still survive to this day.

Effects
Gently tapping a key produces tremendous amount of force within the system. Under inspection, the dampeners appear to magnify the weak pianissimo from an outro into a roaring crescendo. A glitz showtune could fill an entire metropolitan area with song, unimpeded by any obstacle. Tapping into this exchange can produce great, albeit brief, energy reserves.

As a lover of fine arts selection, the keyboard is very picky to which users it reacts with. Those with some innate yearning or appreciation for the musical arts are masters on the stool, and immune to the side effects. Namely, getting crushed like a nattering fly. Those without any prospects, or who intentionally flummox around, will find all their fingers suddenly broken. As the piano took a while to grow interest in musical circles, the downside is also delayed until a random future time.
