Dr Yonit Kosovske will be a panellist at an interdisciplinary event “Music of the Spheres – Exploring Harmony & Resonance in Physics and Music” as part of the Galway Science and Technology Festival. Yonit will share highlights from her ongoing research of Italian keyboard chromaticism in the 16th–17thcenturies, a time of scientific exploration in many fields, including music theory and acoustics. Through the work of innovative individuals such as Nicola Vicentino, Gioseffo Zarlino, and Vincenzo Galilei, (among many others who had multifaceted careers as music-theorists, scholars, authors, composers, instrument-makers, and musician-performers), their ideas impacted tuning systems, inventions of multi-tonal keyboards with over 31 notes to the octave, and harmonically-radical pieces of vocal and instrumental music. This 2-hour event is sponsored by the Royal Astronomical Society and will take place at 7pm on 20 November in the O'Donoghue Centre, University of Galway.
