What is an Acoustic Decaphonic Piano?

Explore the innovative world of the acoustic decaphonic piano in this illuminating lecture by Prof. Paweł Nurowski. Discover how this unique concert hall instrument, created for renowned jazz pianist Leszek Możdżer, revolutionizes traditional piano design by using only ten sounds per octave instead of the conventional twelve. Delve into the scientific, technical, and aesthetic challenges overcome in its creation, and learn about the collaborative effort between physicists, mathematicians, and piano craftsmen. Gain insights into various musical tuning systems throughout Western music history, including Pythagorean tuning, just intonation, and well temperament. Understand the mathematical principles behind these systems and how they relate to the decaphonic piano's innovative design. Experience audio comparisons of different tuning systems and learn about the instrument's world premiere concert. Suitable for all audiences, including those without musical education, this lecture provides a comprehensive look at the intersection of music, mathematics, and physics in instrument design.
