Introduction to Upright Pianos. The first square shaped piano was invented by Frederici of Gera, followed shortly by Johannes Zumpe. In the nineteenth century, John Isaac Hawkins of Philadelphia developed the upright piano and the iron frame. This frame could hold the tension of thicker strings, giving the piano a bigger, richer sound. Upright pianos come in many sizes. The Spinet Piano was first produced around 1935.
