A simple synthetic-based, sine wave-generating freeware program was used as a sound source for creating single pulses and long static tones in several different tonal pitches. No additional sound design or other analog or digital processing was used during the creation of the sounds. The single sound elements were layered and sequenced into different movements of varying shapes and colors, focusing on the pure essence and aesthetics of sound. Each track interweaves longer, stretched, tonal segments and rhythmic patterns into sine-curved compositions. The four Sinus tracks were sequenced at 120 beats per minute in 1999 by Steinbrüchel. They were previously released as a personal CD-R edition of 10 copies. Digital music kindly released by The Tapeworm on analog cassette in 2012. Biography: Steinbrüchels musical work deals mainly with the texture and atmosphere of sound. In the studio, he works relentlessly towards the creation of new sounds. The accumulation, collection and the arrangement of those sounds is revealed during his live sets. The sounds one hears in his music form both intricate patterns and spacious landscapes. In his experiments with electronically-created sound, Steinbrüchel portrays an acute awareness for beauty. His productions follow a distinctly sophisticated aesthetic. Flowing calmly through the listener, his music invokes a glowing space which invites the listener to travel within the sound. Steinbrüchels compositions and conceptual arrangements connect him to the genre of New Music rather than club music, locating his work more in the realm of digital sound art. Ralph Steinbrüchel, born in 1969, studied Communication Design at Central Saint Martins School in London, where he acquired a Masters of Arts and Design with distinction. He now lives and works as a musician and graphic designer in Zurich, Switzerland. In 2002, his composition Zwischen.raum (Domizil, Zurich, 2002) was distinguished with the Max Brand Award for Electronic Music (phonoTAKTIK.02 Festival, New York). In the same year, he received a compositional scholarship from Pro Helvetia, Arts Council of Switzerland, to work on his release Circa (LINE, New York, 2003). His last solo release in 2011 was the CD narrow (Room40). -The Tapeworm.
