The cathedral choir offers sacred music both classical and contemporary in worship and in concert. The organ, considered one of the superior organs of Australia, is played by quality organists. The organ, originally in the earlier cathedral, was a two-manual made by Bishop & Starr of London. Expanded in 1916 to a three-manual by George Fincham & Sons of Melbourne, it was rebuilt again in 1958 by J. W. Walker & Sons Ltd of London, and renovated between 1999 and 2005 by Gibbs & Thomson. The acoustics and 650 seating capacity demand frequent concerts. Appearances of the Tasmanian Symphony Orchestra, Hobart City Band, massed military bands, the Royal Copenhagen Chapel Choir and the Sydney Brass Quintet were features of 2008.
