Although the organ was built for a privately owned timber structure, Edmund Schulze must have suspected that the instrument would eventually find its way to a church environment. The scaling and power of some of the stops suggest as much and - in Armley - the acoustic approaches that of a small Cathedral. Indeed, although the reverb time is just in excess of 3 seconds, St Bartholomew's Church is a very resonant building, resulting in a significant component of reverberated sound being present even in recordings taken close to the pipework. The organ is situated in the chancel area, high on the north side and its power is very keenly felt in this part of the church. Further west, the power and brilliance is tamed (the famous five rank Great Mixtur becomes less strident) and the church's resonance increasingly affects the organ's sound, as would be expected.
As has been discussed, the organs of Schulze were highly influential to the organ builders of England in the latter half of the 19th century. In true German romantic tradition, this instrument sets the flue chorus at its heart, but – unlike quite a few of its continental contemporaries – a reasonable variety of chorus reeds are provided. Indeed, for a builder who was noted for his innovations and developments in flue pipework, the reeds at Armley are of a uniformly excellent quality and expand the range of suitable repertoire significantly. For example, whilst it would be expected that the German late classical and romantic music of the likes of Mendelssohn, Rheinberger, Liszt and even Reger would sound good on this instrument, much of the French romantic period works well too. Although the Schulze sound is quite some way from that of a Cavaille-Coll, most of the basic constituents of that style of organ are present nonetheless. English romantic repertoire is also reasonably well catered for, albeit the sounds of later Willis and twentieth century Harrison have moved some distance away from mid Victorian Schulze. Music from earlier periods can be successful, although the lack of mutations inevitably means that not all baroque music can be performed authentically.
The four manual divisions have what can be described as “terraced dynamics”, with the Great containing the loudest stops, whilst the Swell, Choir and Echo have progressively quieter sounds. The Pedal underpins each division very effectively and even the quietest stops of the Echo are generally not overpowered by the Pedal 16' Sub Bass. If a quieter 16' tone is desired, there are coupling options on all manuals. During the latest rebuild, the Choir and Echo divisions were moved to the same level as the Great, thus allowing the more delicate sounds contained here to be heard more effectively. The Swell is situated above the Great and speaks out clearly into the Chancel – the highly efficient enclosure allows for considerable dynamic changes to be employed. Despite its romantic leanings, each manual has a proper chorus based on a 16' pitch – the Great Mixtur, Swell Cymbel and Choir Cornett all have harmonics from the 16' series sounding in the treble of their compass and so require an appropriate 16' manual stop to be drawn for these stops to sound as intended.
