Architecture remains an integral topic to discuss when historical changes occur in time periods and the many art forms begin to change as well. This is especially present during the artistic transition from the medieval period to the Renaissance, where proportions and symmetry are reappearing ideas originating primarily from Greek and Roman times. During the Renaissance period, architects such as Bartolommeo Bandinelli were known for the exceptionally designed domes of Florence, larger than ever seen before. While the exterior elements of Renaissance architecture were impressive in their own right, the interior elements were also unique, particularly the acoustics of the structures. The acoustics of the cathedrals in Italy were designed to adapt to the type of music of this time. The Renaissance gave rise to the use of polyphony which is a faster and more multi-layered type of music. Renaissance architecture and acoustics were considered a divine connection to the harmonious nature of the world using proportion and symmetry that led to modern techniques of sound diffusion in concert halls and sound booths, as well as design techniques used today in fields of architecture and engineering. Renaissance churches were designed with the idea of ​​the usefulness of churches at this time. Unlike most modern churches, Renaissance churches were not only used for daily services and monophonic chants by monks, but the acoustics had to take into account annual festivals and large gatherings of larger organizations. This required the use of the church not only for monophonic, but also for polyphonic music. Renaissance church architects designed the space for both needs.
