Opus 63

Holy Trinity Church RC
Harlan, Kentuky
Year of Commission 1989

Under the leadership of Brother Mark Ligett, OFM, the Franciscan Monks of Holy Trinity Mission purchased this instrument in 1996.

This organ was replicated three times as Opus 56, 63 and 88. The keyboard compass is 63/30.

To increase the flexibility of this one manual and pedal organ, Martin Ott added from g32 a Pommer 16’ and a Sesquialter 5 2/3’ + 3 1/5’. All manual stops have split keyboard (divided slider) between keys f#31 and g32.

This instrument, with the exception of the Subbass 16’ section, is on casters. The keydesk can also be removed to reduces its size and make it possible to transport it in a commercial building elevator to any floor.

Footprint dimensions: Width is 54'', depth without manual keydesk is 27'', depth with manual keydesk is 33'', depth with pedal keyboard + bench is 52''.

Note on Divided slider

When the organist transposes the right hand one octave higher, the Pommer 16’ plays at 8’ pitch. In essence the 16’ becomes the 8’; the 8’ becomes the 4’; the 4’ becomes the 2’, and the Sesquialter becomes the 2 2/3’ + 1 3/5’.

By increasing the key compass to d3 (note 63) and splitting the keyboard at f# - g (notes 31 & 32), the unpleasant overlapping of notes at the middle c (note 25) is eliminated, and one has enough keys at the top end (d3) of the keyboard for most written music.
