Fratres
Fratres, meaning "brothers" in Latin, is a composition by the Estonian composer Arvo Pärt which exemplifies his tintinnabuli style of composition. The first version was written in 1977, and was followed by a wide variety of arrangements for other instruments. It is a "mesmerising set of variations on a six-bar theme combining frantic activity and sublime stillness that encapsulates Pärt's observation that 'the instant and eternity are struggling within us'."
