St Mary’s, Maidenhead

At the heart of this new three-manual instrument is the pipework from a large, fine two-manual J W Walker organ built in 1932 for the Great Hall at Wyggeston Grammar School for Boys, Leicester. This has been augmented with four well-matched ranks from a contemporaneous extension organ built by Rushworth & Dreaper for St Margaret’s church, Aspley, Nottingham in 1933 and now redundant; these R&D ranks make up most of the Pedal and Choir organs of the new instrument.

In addition, a few select ranks have been retained from the previous St Mary’s organ—most recently rebuilt by John Males in 1986—and suitably revoiced; the Choir Clarinet is former stock from the firm of the late Peter Collins.

Three digital ranks have been employed to add weight to the pedal division where space does not permit the necessary pipework, and some judicious extension / borrowing has been employed to increase the flexibility of the available ranks.

from Matthew O’Donovan, Director of Music, St Mary’s, Maidenhead

We owe a huge debt of gratitude to Jonathan Wallace and his team from Henry Groves & Son for the marvellous three-manual organ which graces our newly-reordered church building. Having had the opportunity during the project’s earliest stages of planning to see and play some other Groves instruments, I was confident that they were the right firm for the job, and I have not been dis­appointed. The highest level of professionalism, care and attention to detail was shown throughout the project, from its initial design, through the organ’s complex installation (which involved extensive collaboration with the architect and contractors responsible for a major redesign of the 1960s building, and working around unexpected delays in the building work) to its final voicing and completion. All this was undertaken at a very competitive cost and to an excellent standard of workmanship. Jonathan and his team were a pleasure to work with throughout, and we are now blessed with a fine instrument, built to last.
