Written in 1989 Arvo Pärt dedicated this work to Christian Grube and the Staats- und Domchor Berlin. The composition employs the tintinnabuli style which Pärt invented in the mid-1970s. Highly technical for this amateur, please check the Wiki link below for a detailed analysis of this beautiful piece.
For me when mostly the only bass in the Kito Choir, it was probably the most demanding piece I have ever sung. There are no fixed bar-lines together with long drawn out notes which demands complete attention to the conductor. As a person with as strong sense of rhythm, initially my inner metronome was at odds with the conductor. In the early 2000s I did not have the benefit of YouTube which makes life so much easier today. A very ambitious but rewarding work for small vocal ensembles.
