The new medieval organ commissioned for the Project was launched at St Teilo’s church, St Fagan’s National Museum of Wales, on 8–9 April 2011. It has been designed and constructed by the Worksop firm of Goetze and Gwynn, who have extensive experience of working with historic organs – not least those of the Tudor era. In 2000–2001 they constructed two other instruments in their workshop following the discovery of two historic organ sound boards in Suffolk.
The new organ follows the same late-medieval principles and processes developed and applied to the two Suffolk organs. It has also been specifically designed to accommodate changes in performance practice (e.g. music sounding 'in C' rather than 'in F'), allowing research into 16th- and 17th-century repertoire for organ, and organ with voices.
The organ case, organ stool and accompanying double-sided music desk (a copy of the late medieval cantor’s desk at Ranworth, Norfolk), are all made from English oak. The carved wooden frieze and pipe shades of the case are based on late medieval Welsh idioms, including the famous organ case (c.1520) that survives at Old Radnor. Painting and gilding have been undertaken by the artist Fleur Kelly, using materials authentic to the early sixteenth century. Fleur is an Italian-trained specialist in medieval and Renaissance painting techniques who worked on the painted rood screen and panels at St Teilo’s church.
The new organ will move to various locations on occasion to enable specialist use within the liturgy and for research. At present it is 'in residence' in St Davids Cathedral.
