Pipe Organs : Their Acoustcs, History and Control

Speaker:  Andrew Moyse

Andrew Moyse, President of the Institute of British Organ Building, has for many years been one of the senior partners at Nicholson's the organ builders and repairers.  In this talk he will cover the physics behind the different tones of the pipe organ and will also review their history and the ways in that the control of the sound has changed in recent years.

The talk is of particular interest because of the program of repair and restoration of the Salisbury Cathedral Organ which is currently under way.
