Yamaha Gives Brass a Deep Freeze

To optimize the playing experience and improve the sound, Yamaha now offers Cryogenic Resonance Restoration, a proprietary method of deep-freezing brass and metal woodwind instruments that reduces residual strain in the metal.All metal faces a certain level of stress is always introduced as a byproduct of the intense heat and pressure required to shape and assemble any brass or woodwind instrument. To optimize the playing experience and improve the sound, Yamaha now offers Cryogenic Resonance Restoration, a proprietary method of deep-freezing brass and metal woodwind instruments that reduces residual strain in the metal.

“The goal with our cryogenic treatment process is to provide the instrument with that broken-in feel, which normally takes years to achieve,” said Bob Malone, Director, Los Angeles Atelier, Yamaha Corporation of America. The cryogenic procedure is carried out at Yamaha’s 5,000 square foot Los Angeles Atelier, a dedicated instrument design, testing and restoration center located at the company’s headquarters in Buena Park.

Once inspected, the instruments are cleaned using ultrasonic sound waves. Instruments are immersed in a freezer at room temperature before being brought down to -325 degrees Fahrenheit. Then, each instrument is gradually returned to room temperature, which takes approximately 24 hours from start to finish. Once complete, the process simulates years of aging and breaking-in. Cryogenically treated instruments provide a more resonant, centered tone, an even timbre throughout their range and improved response.
