piano
Let an agent explain the piano and its mechanism, relay types, history and repertoire from music sources, describe mechanical, electronic and public variants, and distinguish the piano from the harpsichord, organ, keyboard synthesiser and celesta.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the piano and its mechanism, relay types, history and repertoire from music sources, describe mechanical, electronic and public variants, and distinguish the piano from the harpsichord, organ, keyboard synthesiser and celesta.
A keyboard musical instrument in which pressing keys causes felt hammers to strike strings, whose vibration is amplified by a soundboard, invented by Bartolomeo Cristofori around 1700 and developed into the grand and upright piano, with mechanical variants such as the player piano, coin-operated nickelodeons and orchestrions or organised pianos, the reed-based claviola, and electronic and digital pianos that reproduce the sound; the piano is central to Western classical, jazz and popular music, and street pianos bring it into public spaces.
What it is for: Making music.
It can be explain mechanism and types; relay history and repertoire; describe variants; distinguish from other keyboards.
