The '''piano''' is a percussive [[keyboard]] instrument, in which an action of felt-covered hammers strike strings stretched on a metal frame attached to a resonant soundboard.

The history of the piano is closely intertwined with the standardization of [[12edo]] in the West. The development of steel frames with precision machining gave them the necessary capacity to hold the high level of tension (~~18–30 tons~~) to remain in tune reliably over time.

The piano can be used to play microtonal music in a variety of ways. A single piano's strings can be retuned. ~~The~~ strong advantage that this provides for microtonal music is that due to pitch exactness and precision machining, an acoustic piano can also be constructed or rebuilt for essentially arbitrary pitches and tuning systems, satisfying any exact pitch placement that desired.

However, large departures from intended tuning, for example, from 12edo ― require changes to string length, gauge, tension, scaling, or even the frame and soundboard, rather than simply retuning the existing strings. A typical piano will only handle about a semitone of retuning before breaking strings becomes an issue. Additionally, excessive string stretching produces a timbre that sounds increasingly inharmonic and more bell-like.

As such, purpose-built microtonal pianos ~~(as well as similar keyboard instruments)~~ are required to ~~therefore~~ accommodate tunings that would be impractical or unsafe to realize by retuning a conventional piano~~. Plenty of such keyboards are showcased on the dedicated edo pages on the wiki~~. Likewise, multiple pianos can be used: a solo player can play two keyboards at a right angle, or many players can play many pianos.

Electronic plugins like {{W|Pianoteq}} can be used to retune a modeled piano to arbitrary pitches with high precision, without the mechanical limitations that are found in the process of building a physical instrument.
