Three organs are in regular use to accompany the daily services.
The Apse Organ, situated behind the high altar in the retro-choir, is used to accompany choral services and congregational singing.
The 3-stop Hindmarsh Organ in the Lady Chapel is the most frequently used instrument: each day Lauds and Vespers (except on Sunday afternoons) are accompanied on this instrument.
The renowned Grand Organ, at the back of the Nave above the West Door, is used liturgically only before and after High Mass, as well as for organ recitals on Sundays at 4.45pm and the annual Grand Organ Festival.
