2) Development of the cast iron frame
3) Invention of the upright piano
4) Introduction of the double escapement mechanism

Answer 1

The invention of the upright piano did not take place during the 1800s; it was developed in the late 18th century, predating the significant piano advancements of the 19th century.

Step-by-step explanation:

The technical advance for the piano that did not happen during the 1800s is the invention of the upright piano. The key developments in the evolution of the piano during the 19th century included the addition of the sustain pedal, the development of the cast iron frame, and the introduction of the double escapement mechanism. However, while the 1800s were indeed a time of significant advancement for the piano, the invention of the upright piano actually predates this period. The upright piano was developed in the late 18th century by Johann Schmidt of Salzburg in 1780, followed by improvements by other manufacturers such as John Isaac Hawkins and Robert Wornum over the years.
