Theosony is a neologism meaning 'Sonic Theology' or 'The study of God through Sound'.
Theosony is a neologism penned by Irish singer and theologian Nóirín Ní Riain. The word has both Greek and Latin elements. It is the study of sound within religion, most dominantly the Roman Catholic and Christian beliefs. When speaking to the BBC, Ní Riain said:
The Christian tradition has been dominated by the visual.'God's sound' can be heard in nature, in human speech, and in contemplative silence. From before I learnt to speak I was always 'sounding'.
The BBC reporter added:
The transparent sound of Noírín ní Riain's voice has been described by her friend the poet John O'Donohue as "a celestial staircase, leading to the presence of the divine", and we hear it juxtaposed at times with "the frogs' chorus" (as another contributor describes it) of the sound of the monks and their traditional chant.[1]
