Cutting-edge computer modelling software has enabled a long-lost, trumpet-like instrument to be recreated allowing a work by Bach to be performed as the composer may have intended for the first time in nearly 300 years.

The software was originally developed by a University of Edinburgh PhD student, funded by the Engineering and Physical Sciences Research Council (EPSRC), with the aim of optimising the design of modern brass instruments.

Computer modelling is an emerging technology in instrument manufacture, but the new software offers unprecedented accuracy in terms of ensuring a brass instruments design delivers the required shape, pitch and tone
