Small studio upright acoustical pianos with only 65 keys have been manufactured for good by roving pianists. Obvious as "gig" pianos and still containing a cast inflexible harp, these are comparatively lightweight and can be easily transported to and from engagements by only two men. As their harp is lengthen than that of a spinet or console piano, they have a stronger bass sound that to some pianists is well worth the Piano Covers trade-off in expanse that a reduced key-set offers.

Cristofori's neoteric instrument remained relatively unknown until an Italian writer, Scipione Maffei, wrote an bugged article about it (1711), including a diagram of the mechanism. This article was widely distributed, and most of the next aeon of piano builders started their endeavor because of reading it. One of these builders was Gottfried Silbermann, greater noted as an organ builder. Silbermann's pianos were virtually direct copies of Cristofori's, with odd important addition: Silbermann invented the forerunner of the concurrent damper pedal, which lifts all the dampers from the strings at once.
