6. Acoustics

Musical instrument (sistro), Pompeii
The Greeks were already aware of the direct relationship between sounds and emitted vibrations. This knowledge formed the basis for the principles and criteria they used to build theatres with considerable acoustic properties.

Numbers were used to explain the physical difference between sounds: Pythagoras was the first to establish a precise mathematical relationship between the pitch of a sound and the length of a vibrating cord, thereby creating the harmonic scale.

Musical instruments were based on the harmonic scale, and were used in Pompeii to accompany the important events of people's lives. Music was an integral part of social activities, marking the rhythms of rituals, games, war, triumph, and death.
