The Piano was invented by Bart Christophori, a talented Italian musician and inventor. The piano started out as an instrument not unlike the guitar, except the keys would pluck the string when played instead of you plucking the strings. The piano has greatly evolved since then, into an instrument commonly used in classical music, Rock, Jazz, and Zelda music. Over time, Bart sold his piano as Christophori wealth declied, but he didn't want his invention to fade away, so he published his blueprints so that more could be produced.
They were read by many, and a bunch of nobilities decided that pianos were pretty swag, and they wanted some in their living rooms. So they started being mass - produced, and with large production comes evolution of the product. Thus, the Piano evolved from a huge, incredibly expensive piece of furniture to a free app on your phone.
I like that you've put in this blog, piano's have swag. Overall I think this is really good.
