Stone-sounding instruments combined with seemingly familiar instruments. The alphabet consists of Orgalitho, Fender Rhodes, lithophone, stone gongs, quarter-tone clavinet, stone tables, stone chimes, hand stones, sine wave generator, gongs, midi keyboard, and an almost inexhaustible variety of larger and smaller sound generators.

The Stone Alphabet is characterized by a great awareness of sound and a power that arises from silence. Often, it is the simple, calm, and subtle moods, colors, and textures that make up the fascination and uniqueness of their music, revealing new listening experiences. Their compositions are created collectively. The result is fantastic sound stories, pointed statements, and often an almost pictorial lyricism.
