Horns have not changed for hundreds of years ... until now. Partly responsible is the inherent beauty of the sounds they produce, which will endure for hundreds of years more. In addition, the process of designing a brass instrument and building a brass prototype is arduous, requiring a number of difficult skills and equipment. With the advent of digital synthesizers, molding brass sounds is reduced to programming devices to produce desired sounds, and electronic brass is available in many digital-studio products. Synthesized brass, however, is among the least compelling musical imitations that synthesizers produce. That largely is because the complexity of air and muscle movement in a horn player's armbrochure is not modeled at all in a synthesizer, and so synthesized brass doesn't sound sincere. And that is why recording artists' tunes, movie scores, Broadway show scores, and television sponsors hire horns sections, arrange their musical parts, rehearse them separately from the band, and incur other nontrivial costs ... The CYBERHORN changes all that. Instead of being solely a piece of brass or solely a digital system, it is both. To capture the nuances and idiomatic sounds of real brass playing, the CYBERHORN starts with playing a real trumpet into a digital system of sound manipulation. The CYBERHORN can be programmed to sound like another existing brass instrument, such as a trombone or tuba, or to invent entirely new brass instruments. The CYBERHORN also can produce a tight horn section in harmony, eliminating the need for horn arrangements because the CYBERHORN enables section playing to be improvised. The CYBERHORN also improves performance by fattening thin high notes and similar manipulations. The CYBERHORN was invented and is played by a computer scientist who has played trumpet since age 8 and now plays trumpet and CYBERHORN professionally. If you would like a horn section on your tune, just email a message to cyberhorn@knowledgeadvantages.com and your attached mp3, and I will record and mix in horn tracks and email it back to you. There is no charge for this work.
