Breaking moulds: A seven-octave Clementi & CO piano from 1812 Authors Joan Josep Gutiérrez Yzquierdo Associació Muzio Clementi de Barcelona Keywords: piano keyboard compass, pianoforte evolution, Muzio Clementi, upright grand, period pianos, musical instrument construction, organology Abstract The standardisation of the piano compass in seven octaves and three keys (88 keys) began in the last third of the 19th century. This growth, although unstoppable since Bartolomeo Cristofori’s invention at the beginning of the 18th century, was both progressive and irregular. The experiments followed one after the other and piled up in dialogue with a society avid for musical consumption, with the demands of composers, and with competition and collaboration between the builders themselves, who were trying to make their way in an absolutely growing market. In the narrative of history, it is advisable to stop to observe and analyse the special cases that stand out or apart from the mainstream. By doing this one may explore other facts and not automatically give credence to a single oft-repeated assertion. In this article we discuss an upright piano from Clementi & Co which is found in Spain and which stands ahead of the usually accepted evolution of the keyboard compass in England.
