The Klais organ

IF YOU SIT in the Auckland Town Hall and look above the stage, you’ll see an imposing array of 82 shining pipes, with a complex control console in the centre.

Behind the façade of the Auckland Town Hall Organ is a very complex system of machinery which produces beautiful musical sounds. The organ contains sets of pipes – over 5000 in total, a wind system, and five keyboards (including one played by the feet).

The pipes produce sound when pressurised air, produced by the wind system, is driven through them. An action connects the keyboards to the pipes. ‘Stops’ allow the organist to control which ranks of pipes sound at a given time. The organist operates the stops and the keyboards from the console.

The following pages will take you step by step through the various parts of the organ and explain why it is as it is.
