Researchers capture pianist hands in Hollywood 3D

Researchers at the University of Southampton are using 3D motion-capture technology to understand the mechanics of piano playing.

Dr Cheryl Metcalf hopes to build a database of hundreds of piano players so she can understand the variations in technique, style and playing habits.

The information gathered will be useful to understand why and how some pianists develop repetitive strain injuries.

It will also benefit students using the system who will be able to see how their technique progresses over time.

Professor David Norris, from the university's music department, and Dr Metcalf explain the benefits of the Hawk system.
