We all know what a piano sounds like. But what do the individual parts sound like? You will find out at a concert that the Prague Spring Festival is presenting in cooperation with the most important Czech manufacturer of grand and upright pianos, Petrof. Individual piano components from the smallest to the largest will be scattered around the premises of the National Technical Museum along with two complete instruments. The they will be heard in a new composition created by Michal Rataj and Jan Trojan on commission for the festival.

The two authors have already encountered each at the Prague Spring Festival at the venue of the National Technical Museum for the premiere of Jan Trojan’s spatial composition Circulation in 2017. “The piano is an instrument of Western musical culture, but its deeper musical essence brings together much more,” says Michal Rataj, explaining the new joint project. “On the one hand, the elegant design of the instrument’s cabinet conceals the mystery of the string as the basic unit setting the sound in motion. On the other hand, what we tend to reveal is the history of the rhythmic drive that is common to perhaps all cultures on earth. One can actually look at the vibrating string and pulsating rhythm as basic musical elements without which music could not exist. The design of the piano gives them form.
