The Wyvern Sonata is an ever popular choice for many smaller churches and has found favour with home organists. Despite their modest size, these organs have two full compass 61 note keyboards and a 30 note fully polyphonic, radiating and concave pedalboard.

The Sonata has a specification of 31 speaking stops voiced firmly in the English tradition and has a full reed chorus on the Swell. A “split-semitone” system is employed, where for example a “C” will emit from a speaker on the left side and C# from the right. On another rank the process is reversed. The effect is to give movement to the sound – just one of many inbuilt features that help produce the character of a pipe organ!

The Sonata, with it’s additional upper work is particularly suitable for the accompaniment of congregational singing, and has more ‘weight’ in the Pedal department plus a 16’ reed on the Swell. There are separate departmental pistons and a set of Generals. The expression pedal is of a robust metal design with non slip rubber tread and finished with brass coloured edging. Toe pistons can be added at additional cost.

This hugely popular organ is also available as the Sonata CH6 a deluxe version that has a wider console with a 32 note pedalboard, wooden roll top and adjustable music desk. The organ comes complete with a six channel amplifier and six external speakers.

Personalising your organ is possible straight from the console via a personal voicing unit now standard on all new Sonatas. This allows control over the following functions:

Reverb Time, Pitch, Windpressure Fluctuation, 6 Different Temperaments, Tremulant Speed and Depth, Pitch Change on Attack, Chiff, Manual Inversion.
