Product details

The octone originally came from the idea of European octone watchmakers. In the 16th century, the Swiss octave watchmaker gave the clock the chimes of the time, and the device similar to the octave was born. In the 18th century, the octave began to separate from the clock and became the only device used to record and play music at that time, and gradually created its unique status. At that time, Switzerland was the center of its origin. At that time, the eight-tone piano was hand-carved on a brass roller, and the steel teeth were driven by a spring to read and write the pronunciation.
