An amazing phonograph that reads the surface of the stone, converting vibrations into natural music.This conceptual construction (resembling a phonograph), where a wooden element replacing a needle reads the irregularities of the surface of a real stone instead of a vinyl record and transmits sound vibrations through a copper horn, is inspired by the creative works of Leonel Vasquez, a sound artist who creates similar art objects. The sound resembles unusual, surreal music, and in the English version there is a play on words: rock music (rock music) from rock (stone), which in this case acts as a source of music.The stone is mounted on a small rotating platform, under which a hidden electric motor (inside the case) with a battery is installed. It is turned on using a switch button, which allows you not to spoil the appearance of the device with wires. The platform is connected to the motor via an axle, the motor turns the stone at a speed of about 30-60 rpm, like a vinyl record. A small wooden element (complemented by a metal plate) touches the surface of the stone, transmitting vibrations to the horn.Since the surface is chaotic, the vibrations are irregular — instead of the usual melody, noise textures are obtained — from relatively sonorous to low muffled sounds.The camera of the case works as an acoustic cavity, the hole amplifies certain frequencies (especially low and medium), bringing sound outside.This art object does not have the task of reproducing music in the classical sense, its task is to read the texture of the stone as a soundscape. A sharp needle would cut into the stone, get stuck or break. The ball glides over the surface without scratching it or collapsing on its own. Also, a large contact area smooths out chaotic micro—vibrations, resulting in a less harsh, more bass and booming sound. The wood dampens ultra-high frequencies, leaving a more dull timbre (and a partial metal overlay should allow you to capture a larger range of vibrations) — this emphasizes the atmosphere of the voice of stone. In fact, this element is not a needle in the classical sense (as on a vinyl record player), but a contact sensor in the form of a sphere that reads irregularities as various vibrations.Place this phonograph in the interior to emphasize the strangeness and uniqueness of the space.
