Pianos evolved gradually until they reached the full-size that we know today, that of 88 keys. The piano was now able to stay in tune for longer and this also allowed it to keep more strings in tune. Furthermore, the classic wooden frames were replaced by stronger, more durable cast iron frames. That’s why, as time passed and the music entered the Beethovian period, pianos started to have a range of 72 keys, which was close to six octaves. They were striving to meet the demands of musical composers and players of that time. That’s why instrument producers like Stein and Broadwood started to put more emphasis on creating high-quality pianos. With time, the piano managed to become more popular than the old harpsichord. Fortunately, later versions were pleasing enough for him. Interestingly enough, Bach was one of the people who popularized the piano, although the story says that he destroyed one early model with an ax because he detested it. It wasn’t as robust as nowadays’ pianos and it could also only have a range of 60 keys after some developments that were brought to it. This initial piano was, however, limited, both in terms of build quality and sound. But the piano was capable of playing sounds both loud and soft (its name actually means quiet and loud), and that’s why it was so appreciated. In terms of that, it was certainly not a progressive instrument. However, this new instrument which came with the brand-new mechanism had a range of only four octaves or 49 keys.


He thought that the harpsichord and the other keyboard instruments of that time needed a revamp and that’s how he created the pianoforte, which used a hammer mechanism to create sounds. The world of music progressed and the piano appeared around 1700, and it was created by Bartolomeo Cristofori. Thus, when composers wrote music for it, they were limited to a range of five octaves only. Long-time ago there were different keyboard instruments and one of the most intensely used of them was the harpsichord, and it only had 60 keys.
