Music and Physics. Does beauty have numbers?

Nowadays, physics and music are separate subjects, however, they are actually closely related and we will demonstrate their relationship through the musical instrument I play, the harpsichord, and its tuning and temperaments. We started by tuning the harpsichord to a selection of the most important tuning systems and temperaments. Then, we did frequency measurements for all the musical notes. Subsequently, we used mathematical proportions and auditive as well as graphical methods to analyse why consonances or dissonances occur. Finally, we used our own data to see if we can reach a better precision than a tuning software, providing not only how much can we improve the tuning, but also the temperament to which each note is tuned, thus breaking down barriers between science and art.
