The NPG's Portrait Gallery's Choral Audio Guide, launched in October 2016, features a narrative, actor Simon Russell Beale, whose voice is accompanied by a soothing choral soundtrack. This soundtrack spans five centuries, from the Tudor period to the Elgar-era, with specific pieces chosen to complement the gallery's 500-year artwork collection. The guide begins with works by Tallis and Wilbye in the Tudor Galleries, and continues with a newly commissioned piece, Te Lucis ante terminum, by James Burton. Throughout the guide, appropriate context is provided for each choral piece, making it a interesting experience for visitors.
