Piano keyboard gives guitar sound effects

Scientists have developed a new piano keyboard fitted with sensors to produce sound effects similar to those heard through string instruments such as guitar. Developed by a team of technicians, composers and musicians at Queen Mary, University of London, TouchKeys allows pianists to try out techniques previously unimaginable on a keyboard. Each key is fitted with a set of 26 sensors that work much like a smartphone’s touchscreen. The sensors know exactly where a finger has been placed, letting the player experiment with sounds. For example, waggling the finger on a key creates the sound of vibrato, often heard from a violin. Sliding it up and down the length of the key bends pitch, like a rock guitarist does, ‘ New Scientist ’ reported. Researchers will launch it on crowdfunding website Kickstarter later this month to raise funds. — PTI
