THE sound of a violin bow across strings can be exquisite. But bowing well is hard to master. Now that smooth grace is encapsulated in a new kind of electronic instrument.
Developed by at in Leicester, UK, the O-Bow uses optical sensors to track the movement of a real violin bow across a groove in a metal instrument. The sensor detects the bow鈥檚 angle and speed to drive the production of digital music in a connected computer. Notes are created using a separate keyboard.
The instrument鈥檚 body is a smooth copper cylinder and the groove holding the sensors is shaped to ensure that the bow doesn鈥檛 skid off. It is easier to play than a real violin because the musician does not have to moderate the downward pressure of the bow onto the string, one of the trickiest elements of playing a violin.

Many different sound effects can be created and manipulated, while rotating the bow also creates a vibrato effect, a technique that novice violin players find difficult to master.
Menzies demonstrated the instrument at the conference in Barcelona, Spain, last month and plans to commercialise it. Listen to the O-Bow here:
